Great Video, Had a new board installed a week ago. AC worked flawless all day long on the first outing. Turned the AC temp up as it was turning into a meat locker. AC turned back on and the trouble began. I have a basement AC with two compressors. Compressor one would buzz and two would turn on. Found your video after talking to Winnebago about the issue. They said it was a stuck relay switch. Your video confirmed the issue. Now the big question. The board has to have a warranty on it. Labor to install the new board is the question. Thanks for the video.
You're awesome bro! Mine is doing the same tonight! Thanks to you I can fix it myself!! Thanks for you instruction!!! Travel safe brotha!!! I'm not sure how much money you've saved me but you're appreciated for certain......
Great troubleshooting, I've been a hvac service, install journeymen mechanic for over 45 yrs.Yes,im 71 years old.I just bought a Winnebago 30 ft 2004 .Never thought i would have to trouble shoot my own rv a/c system because im retired and had enough of this crap.But i wanted to congratulate you on your troubleshooting skills .
My AC unit did the same thing. I thought it was the overload circuit. It is the relay on the board. Now I have to find a relay switch. Thanks for the information. Good Video.
I’d recommend a whole new board since there are other components on it that can also go bad. No point in skimping just to have to do the job again later.
@@RamblinMichigander I am good with electronics. Should be a simple replacement. I will test the board for other problems. I have already ordered the relay to replace it. Thanks for the help.
Great video man. Here it is the 5th of August 2023 and your video is still the first one that covers this repair to fix my ac unit with the same symptoms as yours. I sorta figured that was the problem with mine but wasnt wanting to pay $224.00 for a new control board. But anyway thanks for the video because its going to help out alot of people. My unit was humming or buzzing like yours was and only way to cut the ac off was at the breaker box. The thermostat wouldn't cut it off. Thanks again.
I'm pretty sure this is my issue as well.. Ive got a hum when I cut it off at the wall and have to turn it off at the breaker to get it to turn off. I also hear clicking not all the time but when I do its a lot of clicking. Ive been having to turn it on and off to keep it from freezing up and freezing us out.. we're full-time and the summer was too brutal to try and go without while trying to figure out what was wrong.. Its been a pain searching online( as you know), nothing has matched our issue and a huge checklist of what it could be. I had pretty much decided that if I had to replace everything in that list, I might as well buy a new unit. However, we will be in our house sometime next summer, and I don't want to replace it if I don't have to. I figured I would search the internet one more time.. and voila there you were. You did a great job explaining everything and I feel confident that this is it.. Thanks so much for posting this video..!!
I have the same problem with my a/c unit in my motorhome. I couldnt find a video either till i stumbled on yours, thank the maker you made this video, i was able to follow and confirm my a/c problem. thanks, a GREAT help to me.
I have analog system, can usually hear relay click when therm activates ac. Today, it didn’t. Thanks for showing which relay it is and when I arc’d it, AC started. Amazon replacement board on its way😅. The 3107541-009 was the key.
Just a little diagram 101- the K-4 relay is the compressor relay and the "NO" stands for "Normally Open". The lower right grouping is the 6 pin connector from the control box to the compressor/fan on top. Blue is compressor, black is high fan, red is low fan, with is neutral for compressor/fan, green-yellow is ground. And i'd bet you do have a furnace.
@@shineproproducts Ha! That’s quite a coincidence! Remember, your AC unit may be different such as where the board is located, how difficult it is to replace, etc. But the basics should be similar. Good luck to you!
Mine is the fan side. The fan kicks on then kicks off. You can hear the relay clicking. I'm thinking I'll just replace the board based on what I've seen. I'm also going to replace the capacitor to eliminate a point of failure.
HELP, HELP, I did replace the control panel and only worked for a few hours then it star to do the same, I going to order a new one " hopefully I get a defective device.
Hi, I remember an old video of an investment property you bought. I really enjoyed the restoration type videos on that property. Can you please provide an update on that property? Thanks.
I've had the same issue, and just recently figured it out mine is 30 years old and doesn't have a control board, only separate relays but still the compressor relay stuck on and did the same thing as yours.
Hey. Many thanks for this video. Last trip, we pulled in, plugged in and the Compressor would not fire. Turned the system on and off about 10 times and then it turned over and stayed cool for the whole trip. By the sounds of this video, the relay switch is sticking and likely unstuck itself. Sounds like I should order a board just to have on hand in the event the sticky switch fails completely.
Yes, that’s definitely a possibility. The other thing that causes the compressor to not turn on is the capacitor failing. But I believe the capacitors pretty much either work or fail completely so it’s prob not your issue.
@@RamblinMichiganderif the fan is turning on but compressor not igniting to blow cool air would that likely be relay or capacitor? Other videos have mentioned overload protector
How much did just the board cost? I have a similar problem but ours fails to shut off intermittently and causes the fan to come back on. Then at other times it works without any problems.
Gordon since your bolts were loose shouldn't you be checking/replacing the rubber gasket also? I'd be concerned about future water leaks. Great video by the way! Wish I had electrical understanding like you. Looking forward to your upcoming videos. Cheers! ~M
My propane fridge, small dometic, goes thro a tank of propane in 24 hours. Cools just fine. Gets very hot on counter and outside trailer. Electric works fine. What is it?
I have this same air conditioner in my 2000 Hitchhiker II fifth wheel. Mine will do the same thing as yours but if I shut off the breaker and back on again the compressor is off. It may act up again on the next cycle or be fine for several days. Lately it's been getting worse. The fact that my relay does shut off with power loss makes me wonder if it could be a thermostat problem. Does that seem possible to you?
I’m not an expert but no, that doesn’t sound like thermostat. That sounds like a relay that is sticking but not constantly like mine was. But things like that always get worse. I suggest replacing it asap. If the compressor runs for very long without the rest of the AC unit operating, it could cause damage to the compressor or, I hear, even start a fire. Not worth taking that risk for avoid paying for a $100-ish part.
I wonder how much that board was. The relay is probably in the $10 region and should be a common type available in AutoZone. And yes, anyone with a little bit of soldering skill could swap it in 10min. Good skill to have.
With overnight shipping it was about $110. Yes, I could’ve saved money by having a new relay put on, but I just didn’t have the time. I needed it fixed to be ready for my trip. Plus there are other things on that 20 year old board that could’ve gone bad later. Better to just replace the whole thing.
Thanks man, the exact some problem on a dometic, ive been cutting power from the circuit board for 12 months until i found this video😂

That forehead to shoulder head wipe. I relate.
Thanks for the video, you still helping folks out here.
Good Useful info Gordon. Thanks for taking the time to make Vid.
Great video! Gotta learn about so many systems to keep an rv going. Thanks for the information!
Glad it was helpful!
Hey man. I have a similar AC problem. Thanks for this video. This definitely helped me.
I have been searching for awhile to find a video like this. Thank you so much!!!
You having the same problem?
@@RamblinMichigander yes it just happened yesterday. So I decided to look today and thank God you made that video 6hrs before. Thanks!!
@@shineproproducts Ha! That’s quite a coincidence! Remember, your AC unit may be different such as where the board is located, how difficult it is to replace, etc. But the basics should be similar. Good luck to you!
@@RamblinMichigander yes I checked it out and should not be to bad. We have 2 30' campers and a 30' motorhome so this is definitely helpful.
Ours compressor started sticking yesterday, thanks for the tips. Will replace board.
Thanks, I think I am facing the same problem. Great job.
Thank you for another awesome video! 😎🤙🏻🤙🏻
Awesome!!! I can't thank you enough!!🙏🙏💙

Hi, I remember an old video of an investment property you bought. I really enjoyed the restoration type videos on that property. Can you please provide an update on that property? Thanks.
You were very helpful, thank you.
I recommend an isolator between the board and mounting surface. Other than that-good job on the trouble shooting!
I wish that I had just HALF of your brain!! Happy trails to you!!
Thank you for a great video.
Very helpful mines doing the same thing
Thank you
I've had the same issue, and just recently figured it out mine is 30 years old and doesn't have a control board, only separate relays but still the compressor relay stuck on and did the same thing as yours.
By any chance you have a link to the mother bored you got?
Thanks. I think this is my problem. Approximately how much was that board?
Where did you order the control board from

Yes, after 20 years, it’d be smart to replace that gasket. But that’s a job for another day. Don’t have time to do it before our next trip.
@@RamblinMichigander Just add it to the list of vacation projects LoL!!
My propane fridge, small dometic, goes thro a tank of propane in 24 hours. Cools just fine. Gets very hot on counter and outside trailer.

What is it?
Not sure. Possibly a dirty flu causing a bad fuel/air mix…? You should talk to an rv fridge expert.
