Thank you for all your time and attention to detail. No apologies needed. I stayed to the end and waited for the ferris beuller, " why are you still here" scene.
Finally, nice to see someone who knows their stuff vs. just posting a youtube video that says look at me. On a side observation the battery pack was reverse connected, thus it won't work.;-)
Darren this is fantastic reliable information I personally used your information to replace a squealing blower motor, replace the burner and electrode. Heater works like a NEW unit now. Keep up the fantastic videos and sharing your wealth of information.
Darren, my furnace is nearly identical to the one here and your step by step helped me disassemble, replace Burner and ignitor, clean it and put it back together so that it now works! Thanks!
Darren, As an industrial Sparky my career and owning my company doing so having the young employees that are at the stage of their career you and I were so many years ago I can tell you, you and I have the same teaching structure. Keeping it simple enough to help us that are ignorant about these units like mine that is the second example, same situation how you've got this one on a bench and not accessible in the 5th wheel I've got. I've got the 12vpos with the negative now on a screw of good ground for the 12v input. " The thermo has it's 12 pos and neg as well. I opened and closed the "circuit breaker"/overload that DOT requires but still nothing coming from the unit. Your video is giving great insight of where to look at "what". I appreciate you and your information on this situation that I'm having at this time as winter is rapidly approaching. Luckily I've got the AC with heat pump along with the fireplace in the living room. The space heater is a nice addition if the temps get below the 40deg range as the heatpump tends to not operate with the colder temps. Thank you for the information you've provided sir. Greatly appreciated.
You have a calling to do way more in the area of RV repair training. I’d love to see a series on troubleshooting where the observer could make decisions on what to check next based on what is observed. I know it would take some time to put that together but it could be done. Thanks again, I’ve learned so much from you over the years.
Thank you for the kind comment. You may be happy to hear that we have recently launched a new site called My RV Works Academy. One of the features that we are developing for that site will be a concept following the Choose Your Own Adventure type repair. We will present an issue with relevant information, the student will then make a selection based off of what they think the problem is, they can click that link which will start a video explaining why the decision was correct or incorrect. If the wrong decision was made the video will then loop back to the decision point and they can make another selection. You are right though, developing that is taking us a lot more time than we had anticipated. But, we are developing it. All information regarding our Academy can be found on our Patreon site.
I can't tell you how much your videos have helped me. I'm getting ready to troubleshoot our furnace (in October, of course!). I've already replaced the ATS on our rig solely based on a video you did, and the job was a complete success. If you ever do an actual hands-on school, I'll be planning a trip to Washington. In the meantime, your videos are my school. Thank you!
Great video and info. You hooked up the jumper pack backwards and that's why, the system didn't power up. You put the yellow wire on the positive clamp and the red wire on the black clamp. Thanks for sharing your repair knowledge. Fun to watch and learn 🙂
Your videos are awesome. Keep up the great work. I enjoy your jibber jabber 😂. I can fix stuff. You help me see how to take things apart so I don't break them apart.
Yeah, finally another video. Thanks Darren, love these videos. Binged on all of them and I don’t even have an RV yet but as a remodeling contractor, problem solving is my everyday thing. Nice to see you doing it on other systems. You do it well and I like your style. Keep up the great work. I know that it’s a lot of work to do the videos but totally appreciated. Love the T-shirt.
Hey, this is just an explanation of why the electrodes touching over the burner will cause the controller to shut the furnace down. For flame sensing, the controller board sends an AC current to the insulated electrode. This is current that flows one way and then the other way, back and forth. When the current gets to the flame, the flame only conducts the current in one direction (DC). This is called flame rectification. If the controller board sees the AC current it sent coming back going in only one direction (DC), then it knows the flame is conducting it. If it however it sees AC current that comes back flowing in both directions, then it knows the electrodes are touching (or the insulated electrode is grounding to the burner) because they won't rectify or block it in one direction like the flame and so it knows it's not the flame conducting and it'll shut it down. Of course, if no current returns at all it knows the flame has gone out and will also shut it down.
I have good sail and high limit, expecting electrode to start to spark and gas to open but neither happen. Have 12v going into board from sail and limit switches but not 12v coming back out to gas solenoids. If electrode does not spark (is bad) does that stop 12v to gas valve?
@@hopkinsno5 It does sound like either the ignition, gas valve or insufficient gas pressure from the propane tank. You can check your gas burners on your stove are working for gas pressure. You can listen for the gas valve click as it opens if you feed it 12 volts directly. If it doesn't click, the gas valve could be blocked and you can fix that by blowing it out or maybe it'll need to be replaced. Check the electrodes that they're clean and spaced properly. On the circuit board, it may have an LED light that flashes to let you know it's status or if there's a problem. Somewhere near the circuit board it'll tell you what each sequence of flashes mean. If everything checks out it could be the circuit board itself.
I think your battery booster pack didn't work at the end (49:00) because it was hooked up backwards. You had the red furnace wire hooked up to the black booster cable and the yellow furnace wire hooked up to the positive booster cable. At the start of the video you hooked it up red to red and yellow to black. I've got a 40k btu suburban furnace mounted under the refrigerator in our 2003 Newmar Dutch Star DP with no outside access so I'm trying to learn all I can about trouble shooting it if and when something goes wrong.(We always use the heat pumps for heat when possible). Your videos are a big big help. We live in S.C. If I was in your area I would definately call you. Thanks Darren.!
Great video. I have a Dometic DLFD40 that stopped working. Only would click. Pulled it out after watching your other videos and found a loose wire from the breaker to the board. Hooked it up to test and it would turn on, ignite, then turn of the flame. Kept trying to relight. Checked the valve assembly (after watching your video) and solenoids were good. Did a little more research and found a thread on a site that explained this same problem----you can't bench test without the exhaust manifold on the unit!!! Started right up and ran like a charm! Wish I had known...
I saw your kitty on the floor. At first he looked like a rug. Pretty fur. I am paying attention to you. Right tool for the job! Excellent information. Thanks for your vlog
I enjoy all your videos. I have worked on that same heater. I found a great wrench to use as a backup at Home Depot. It’s called a adjustable plumbers wrench. It’s similar to a crescent wrench but has very slim jaws. Works well in tight places.
Just to help others , my atwood 8525 would run the 3 seconds and stop the gas , I cleaned burner and adjusted igniter , still didnt fix, So i ordered the circuit board and that fixed it, Thank you for your videos.
Shout out to you Darin, thanks thanks and again thanks for the time that you put in to our Community. There are many of us that don’t have this knowledge and you take your time to help us.
Really enjoyed the video. I am new to RVing and I have used an electric heater plugged into our 110 at home. I tried my furnace yesterday since we purchased a used one and was told it did work. The blower would come on but then shut down. So as soon as the weather warms up with a day off, I will check my furnace. Again great video.
2 days ago I decided to tackle my air conditioner not turning on. Instead I have fixed my furnace and hot water heater. I have learned more about what ac compared to bc from you in a 37 minute video yesterday then I had ever known. And I'm a electronics manager.( Ret.). lol
Great video, really simplified everything for me, now I know how to diagnose mine…..think I’m not getting the feedback voltage back to board, so flame shuts off
Thanks for all your videos. You just helped me solve the problem with my Burner. The probes had moved farther than 1/8 apart.. Moved them back and it fired right up. Thanks again.
1/8” gap is interesting as my 2016 mfg date Atwood manual that came with my AFLD40 says .375 or 3/8” is required distance from spark rod centerline to burner screen.
This is a great learning video, I was able to help a friend of mine in repairing his furnace. It turned out to be the orifice tube had a spiderwebbed inside of it. Thank you for your videos
EXCELLENT tutorial and detailed discussion, you will go far with your attitude and friendly manner of helping. The more you help, the more people will see and that they want to help you grow. Keep It Up.......
Super job on the propane explanation. Great content! Also, if the propane gets old, it may settle out ssme of the oil (gas reverts to the oil base) and as it gets to the bottom of the tank, the oil will begin to vaporize along with the propane and end up in the gas that is burning. (I'm an old LP tank driver and discovered the issue on some 3-4 year old 100# cylinders that were not used in a timely manner.) The propane needs to be relatively fresh or refilled recently. (I've also had some similar issues with my grill at the campground with oil residual on the tank/hose.) It needs to be used faster - kind of like leaving gasoline get old over the course of a winter - the wax part will loose its potential unless you put in an additive. Sorry - no additive for the propane.
Darren.... best furnace video yet. I also did notice as Hans did, that you had the positive and negative backwards on your power supply. I was thinking that a video in reference to tires would be great such as maintenance, inspection and explaining what all the information on the tires mean. There are clips on You tube however. you explain things so well.
The burner is telling you then that they had liquid P coming into the system which gives you a "uncontrolled burn" instead of a "controlled burn". Which then means the company filling the larger house tank is over filling the tank. The tank should only be filled to 80%. There are a couple possible reasons for that, but this is about the furnace issue. Very good class, Thank You.
Darren discuss this a little bit in the following video. The liquid in the line is not from the LP. It is being released from the rubber hoses connecting the tanks and cylinders to the RV LP appliances: czcams.com/video/WG8UxIIrrQQ/video.html
Thanks Darren enjoy watching your videos of repair and maintenance very educational I have been watching your videos now for about six monthsThanks Wayne
Good job Darren. If there is a choice in learning I prefer too much information rather than just a brush on the surface. I came out of my industry in 1984 to teach vocational education. Four years later I went back to industry. An instructor should avoid assumptions that a student comes to the class with predetermined knowledge for it might be wrong or not enough to work into the depths of a procedure or device. In late 2019 I bought a 30 year old trqavel trailer to be my home. It’s my second RV. I have renewed the water heater with a new $20.00 thermocouple. I’ll work the furnace in May when weather is prime for such a project.
Darren, you are THE BEST guy at what you do that I have ever met! Thanks for always doing fantastic videos. Oh, my wife laughed about the woof-woof part. :)
As I said before, you are an awesome instructor. Best how to videos I have watched. Too bad you didn't teach my college classes! Keep up the more than great videos!!!
Hi Bob, We are so glad to hear that our videos were able to help you! If you would like to support us please consider becoming an "RV Community Supporter" on our Patreon site: www.patreon.com/myrvworks Happy Camping, My RV Works Media Team
You have passed on so much knowledge. It is fantastic. I was actually working with a Dometic/Atwood Service Tech and I was not understanding what he wanted me to do thru emails. But then I found your videos and was able to get it going again. And Ya the dumb exhaust tube has to be on. That bit me for a bit too. LOL, Thanks for all your knowledge.
Darren- another great video that really showed me how to troubleshoot my furnace and what components make the thing work as well as what symptoms we can expect to present. I really appreciated the drill of if this is happening then what does this mean (i.e. igniter is firing and gas valve is opening then could it be the sale-switch?) That type of question and check-on-learning is particularly helpful! These are the best videos that I've found by a certified professional trying to help to repair our RVs! Thank you!
Absolutely awesome. Thanks so much! GREAT detailed video! You helped me troubleshoot my heater problem. One of your other videos "Atwood 8531-IV RV Furnace With Intermittent Heat " is the EXACT problem I'm having. I appreciate your expertise and that you've posted it to CZcams. THANK YOU!
Love.your vids. Most hard installed appliances have a switch nearby for service work. Called a service swirlch. It is there to protect any serviceman from AC shock. Also very convenient to turn on and off for servicing. Thanks for your very well made vids. I have learned a lot from you
Unless you said and I missed it since oil is the reason for the burn out on the head how do we eliminate the oil. These are the type of information is really really good. Thank you so much for taking the time to go into detail information.!
Thanks for all your help now I think I know what’s wrong with my furnace 👍Question will the burner head also keep heat from getting hot instead just warm???
Awsome video Darren - If I was seeing right the second time after the repair was completed you hooked up the polarity wrong - Yellow was ground and you hooked it up to the positive of the battery booster - if you watch your video you'll see what I mean.. Also being that that heat chamber was exposed to excessive heat due to the burner not regulating the flame I would of done an inspection for heat crackes due to the chamber being over heated...
wow I'm so thankful that you're doing this because of you doing this these videos I'm starting to learn and I'm living in an RV I've already fix the propane system in a thermal coupler and stuff like that and got my gas propane system working for the frigerator absorption refrigerator of course I still haven't figured out how to get the thermocoupler exactly out so I can scrape it off and do it all the black Carbon I had to do it the hard way with it in there but I mean I did do it and it worked
Hey Darren, I had some great instructors at RV Tech school last year but I really understand things more with the way you teach. Have you thought of becoming an instructor at NRVTA in Athens, TX or other schools? Thanks for sharing all of your knowledge. 👍🏻
Great video, thanks for taking the time and explaining the details of the entire circuit and function of the heater. our RV uses a 450D Aqua Hot system but it's nice to watch other systems and how they work in case someone asks me a question at an RV park. BTW the video on the 450 unit was fantastic!
@@MyRVWorks yeah! Definitely was..as shared previously..I live in a camper...due to hard times... since there's only me,I have to keep it up...you are very helpful to me...absolutely!! Thank you so much! 😊😊😊❤
Thanks Darren, this is really helpful. Love the many tips and tricks you're sharing. I'm about to dive in and see if I can find out what's going on with my 2008 NT-16S. Fan blows, I hear a tick, I smell faint LP, but no flame/ignition. It cycles 3 times as per the instructions then shuts off after 90 seconds. I replaced the electrode but to no avail, so I figure it's either the module (bad ignitor component?) or insufficient LP caused by a bad valve or blocked LP pinhole. Anyway, with the info you share, I feel better equiped to troubleshoot it even though I do foresee it'll be a pain to get it out of its hole...

Hi Darren. Fellow RV tech here, located in Tulalip, WA. You are one helluva good teacher my friend. This was a magnificent presentation. 👍👍 I'm going back right now to delete an arrogant/nasty comment I made on one of your water heater vids , and will probably email you. I have some info on the 8940 plus re-liquification of LP vapor that you may enjoy. 😎 Robert
@@ericschweitzer2454 No Eric, I went back and looked. I did delete that rather sharply worded comment. I did leave two others regarding my disagreement with guiding RV owners on servicing LP gas burning appliances, but they were just very direct and factual. Saying he teaches things that could have an owner hurt themselves, void their insurance policy, or take work from other service agencies is not nastiness, it's my professional opinion. In addition to totally deleting that one comment, I also had edited another to soften the language, so I believe the task is done.
Hey Darren; great and informational video. Question is how do you turn the gas pipe out of the gas valve, with the unit installed? Keep the video coming, thanks
The burner almost looked brand new. I figured out why it will kick on and the burner will fire up and then the burner will kick off. The exhaust is reaching 171. So the limit switch is tripping then it cools down below 190 and the burner fires back up.
We have a 13 year old Keystone Sprinter. The AC unit went and the service call tech quoted me over $2K to replace the roof top unit. He said it was just the fan motor which is encased in styrofoam. He could replace that for over $600. But the rest of the unit could go after that so it wouldn't be worth it. These units cost about $1000 or more without install. They typically do not last beyond 15 years according to the tech.
Thank you for all your time and attention to detail. No apologies needed. I stayed to the end and waited for the ferris beuller, " why are you still here" scene.
Darren, there is no denying your enthusiasm for this stuff! That is what makes you such a good instructor.
You are the MAN!!!! With this video I was able to fix my furnace May God continue to bless you with your many gifts ,talents, and trades 👍
Finally, nice to see someone who knows their stuff vs. just posting a youtube video that says look at me. On a side observation the battery pack was reverse connected, thus it won't work.;-)
Darren… LOVED this one! One of your best, frankly. Helps me diagnose my suburban. OH.. as an amateur astronomer - I LOVE the shirt!!
This was a MASTER CLASS, I got a ton of value out of this one !!
I love all the Video's I was a mobile technician and now a shop foreman.Super helpful videos especially the furnace and A/C ones.
I watched this video again and once again it saved me. This video is my favorite furnace video.
Darren this is fantastic reliable information I personally used your information to replace a squealing blower motor, replace the burner and electrode. Heater works like a NEW unit now. Keep up the fantastic videos and sharing your wealth of information.

I saw this stupid guy did that
Thanks for taking the time to show us how to trouble shoot the heater.
As I said before, you are an awesome instructor. Best how to videos I have watched. Too bad you didn't teach my college classes! Keep up the more than great videos!!!

Going to level one cert. training next week and this video helped alot. thank you!
You have passed on so much knowledge. It is fantastic. I was actually working with a Dometic/Atwood Service Tech and I was not understanding what he wanted me to do thru emails. But then I found your videos and was able to get it going again. And Ya the dumb exhaust tube has to be on. That bit me for a bit too. LOL, Thanks for all your knowledge.
Darren- another great video that really showed me how to troubleshoot my furnace and what components make the thing work as well as what symptoms we can expect to present. I really appreciated the drill of if this is happening then what does this mean (i.e. igniter is firing and gas valve is opening then could it be the sale-switch?) That type of question and check-on-learning is particularly helpful! These are the best videos that I've found by a certified professional trying to help to repair our RVs! Thank you!
Absolutely awesome. Thanks so much! GREAT detailed video! You helped me troubleshoot my heater problem.
One of your other videos "Atwood 8531-IV RV Furnace With Intermittent Heat
" is the EXACT problem I'm having. I appreciate your expertise and that you've posted it to CZcams.
THANK YOU!
Love.your vids.
Most hard installed appliances have a switch nearby for service work. Called a service swirlch. It is there to protect any serviceman from AC shock. Also very convenient to turn on and off for servicing.
Thanks for your very well made vids. I have learned a lot from you
Great video, I had a problem with a furnace and it was the control board but the video helped greatly determine what the problem was.
Your a very good teacher/tech
All your videos are great information 👍 thanks you
Keep these awesome video coming! I’m restoring my 2006 and I have applied your experience. Thanks Darren
Unless you said and I missed it since oil is the reason for the burn out on the head how do we eliminate the oil. These are the type of information is really really good. Thank you so much for taking the time to go into detail information.!
Thanks for all your help now I think I know what’s wrong with my furnace 👍Question will the burner head also keep heat from getting hot instead just warm???
Most excellent video thank you very much
Awsome video Darren - If I was seeing right the second time after the repair was completed you hooked up the polarity wrong - Yellow was ground and you hooked it up to the positive of the battery booster - if you watch your video you'll see what I mean.. Also being that that heat chamber was exposed to excessive heat due to the burner not regulating the flame I would of done an inspection for heat crackes due to the chamber being over heated...
Great video as usual... Thank you. As a fellow PA resident, joined your Patreon
Another excellent video. Thanks! 😀
Another great video thanks I love learning how things work to be able to troubleshoot,
wow I'm so thankful that you're doing this because of you doing this these videos I'm starting to learn and I'm living in an RV I've already fix the propane system in a thermal coupler and stuff like that and got my gas propane system working for the frigerator absorption refrigerator of course I still haven't figured out how to get the thermocoupler exactly out so I can scrape it off and do it all the black Carbon I had to do it the hard way with it in there but I mean I did do it and it worked
Hey Darren,
I had some great instructors at RV Tech school last year but I really understand things more with the way you teach. Have you thought of becoming an instructor at NRVTA in Athens, TX or other schools?
Thanks for sharing all of your knowledge. 👍🏻
Great job having an understanding of circuit ales trouble shooting a lot easier thanks
Thanks for this one. It answer a lot of my questions about how the furnace works
Really appreciate the videos, Darren!
And I always wondered about the filter...or lack there of...now I know😊
This is amazing. Thanks so much, Darren! I think your battery pack may have been okay but the positive and ground were crossed there at the end?
Great information and great explanation of everything your doing and how things work!
Nice job ! Thank you!
Great video, thanks for taking the time and explaining the details of the entire circuit and function of the heater. our RV uses a 450D Aqua Hot system but it's nice to watch other systems and how they work in case someone asks me a question at an RV park. BTW the video on the 450 unit was fantastic!
Thank you very much...I live in a camper and I follow everything you're saying.. very useful data!😊😊
Glad it was helpful!
@@MyRVWorks yeah! Definitely was..as shared previously..I live in a camper...due to hard times... since there's only me,I have to keep it up...you are very helpful to me...absolutely!! Thank you so much! 😊😊😊❤
Thanks Darren, this is really helpful. Love the many tips and tricks you're sharing. I'm about to dive in and see if I can find out what's going on with my 2008 NT-16S. Fan blows, I hear a tick, I smell faint LP, but no flame/ignition. It cycles 3 times as per the instructions then shuts off after 90 seconds. I replaced the electrode but to no avail, so I figure it's either the module (bad ignitor component?) or insufficient LP caused by a bad valve or blocked LP pinhole. Anyway, with the info you share, I feel better equiped to troubleshoot it even though I do foresee it'll be a pain to get it out of its hole...
Long? Yes. Informative? Absolutely. Thanks.

Absolutely agree with Jeff, best videos ever and recommending them also.
Learning sooooo much from your videos!! Thank you so much!
not long enough bud, Thank you for another great video
Hi Darren. Fellow RV tech here, located in Tulalip, WA. You are one helluva good teacher my friend. This was a magnificent presentation. 👍👍
I'm going back right now to delete an arrogant/nasty comment I made on one of your water heater vids , and will probably email you. I have some info on the 8940 plus re-liquification of LP vapor that you may enjoy. 😎 Robert
Thanks, Robert.
Your comments are still up, so get on that!
@@ericschweitzer2454 No Eric, I went back and looked. I did delete that rather sharply worded comment. I did leave two others regarding my disagreement with guiding RV owners on servicing LP gas burning appliances, but they were just very direct and factual. Saying he teaches things that could have an owner hurt themselves, void their insurance policy, or take work from other service agencies is not nastiness, it's my professional opinion. In addition to totally deleting that one comment, I also had edited another to soften the language, so I believe the task is done.
Another great video. Thanks. Glad you're back.
I learn a lot from these videos. Thanks!
Hey Darren; great and informational video. Question is how do you turn
the gas pipe out of the gas valve, with the unit installed? Keep the video coming, thanks
You're the best Darren! I would like to know what you wear to work. You look very professional.
Thank you!,, do you have a video for taking the furnace motor out and replacing?
What a great teacher! Thank you very much!!!
My 2019 Montana came with a increasing pressure regulator on the far tank that went bad and increased the pressure by even more.
The burner almost looked brand new. I figured out why it will kick on and the burner will fire up and then the burner will kick off. The exhaust is reaching 171. So the limit switch is tripping then it cools down below 190 and the burner fires back up.
This guy is totally awesome!!!!! THANKS
red is + yellow _ you had it around the wrong way when conected to the battery pack ,,, @48.51
I noticed the same thing :-)
We have the same one no tictic tic sound and no smell of gas. Air conditioner works fine off the wall thermostat
Thank you for the information...
We have a 13 year old Keystone Sprinter. The AC unit went and the service call tech quoted me over $2K to replace the roof top unit. He said it was just the fan motor which is encased in styrofoam. He could replace that for over $600. But the rest of the unit could go after that so it wouldn't be worth it. These units cost about $1000 or more without install. They typically do not last beyond 15 years according to the tech.
