RV Lost Power? Could be Overheating! Magnum Inverter Cooling Fan Replacement
Vložit

- I replaced our Magnum MagnaSine internal cooling fans due overheating failure and thought I would walk though doing it. When the lights go out it could be your inverter overheating due to cooling fan failure.When that happens the inverter/charger overheats and shuts down to cool and then turns back on over & over again. You may care to check the cooling fans which seem to have a useable lifespan of 5 years. The fans were $38 shipped and here is where I found them....

Although I will NEVER EVER attempt to do this type Of work, I just enjoy watching you guys! Thanks for sharing...
Thanks, David and Brenda!
Great video David. Thanks
Thanks for sharing David
Good info David, thanks for posting. I would tackle it now that I have watched you do it.
another great informative video! I so appreciate these valuable videos. I agree with others I am surprised Brenda was so calm and didn't say a peep during this. :)
David next time only one cup of coffee before attempting this project nice job David.

Great information, much appreciated!
Some very good information, thanks.
Dave thanks for the video, watched it twice but still had to come back for that front screw and forgot which way the fans went after I took the old ones out. Should have taken a picture before taking them out. In my defense, I have changed all 5 clearance lights on the front cab, and the entry door shade already today and the inverter was #3 of 11 projects I have to complete before leaving Florida and heading north. Thanks again for all the helpful videos!
Good job my friend David and Brenda
Good work!
Thanks for your video!
Good job.
Thank you!
Grey video, many thanks David
Great info! Be nice to have an over-temp and inop fan alarm. Thx!
David, once again thank you for a great, instructional video. Like you I mounted a fan in the compartment my inverter is located in. The whole compartment get hot from the inverter, I do have the fan controlled by WiFi controller, temp sensing switch.
I wanted to suggest a different headband light that you might like. Made by OLight (Amazon carries them) exceptionally bright (controllable) and a battery that lasts! Their recharging system is quite unique using a magnetic base. They are a bit speedy but rugged and reliable. Mine is over 2 years old now and is used daily (walking the dog!). Once again thank you
Hi...Yes, I ended up removing the cover and shooting a fan at it until the new fans came in just to keep running. :) Thanks for the LED Headband suggestion. I hate the ones I have actually. I looked them up and will surely order. They have a lot of different versions... amzn.to/2MaXCWC
Very informative. Thanks for posting. I need to preemptively change the fans on my Magnum inverter/charger in our 2019 Newmar Dutch Star 4018. I’m not very experienced in doing this type of work, so your video is very helpful. A couple of questions if you’re able to answer: did I read your reply to one of the comments that you wrapped your driver extension in electrical tape? Is that something you recommend? And are the gloves you’re wearing for protection from a shock? Can you recommend any gloves on Amazon or another source? TIA.
Looks like they mounted the inverter upside down. Frees up storage space, but makes it a bear for expected/required maintenance. Maybe put an inline backup switch on that “always hot” line? Could prevent parasitic drain when you think the OEM switch is off.
Excellent video! Was wondering David at the end of the video what type of fire extinguisher system do you have by the inverter? Is it a stand alone or part of a bigger system?
Seperate systems. 4 of them. Foam Engine Fire Suppression and Clean Halon in the Battery area, Inverter area, and Electrical bay.
Here is a videos... (Boy have I lost weight!!!)

I recommend disconnecting the negative (-) ground high amperage capacity cable. NOT the red positive (+) cable. Much safer.
Oddly Magnum recommends removal of the red first. The order is inverted from a typical battery?
All through this video I'm thinking No OOB ever Again LOL
Nice job! How many miles do you have on your rig?
About 27,000. We go from NY to AZ each year though TX and more or less stay put in places we like and not moving around.
Where you get fans
Link in video description.
I think you should tell people that even though there is no power going to the inverter it has large capacitors that hold a charge and can give you a serious shock.
I thought I kind of did by mentioning you need to be careful even with the power disconnected what you touch. Thus the gloves. :)
@Jack Jones Hi Jack....Yes you are correct. I do have a set of electrician tools but it did not have torque screw heads. So I used the long shaft and electrical tape down the sides.
yes, insulated screwdrivers and nut drivers can pay for themselves in damaged equipment.
@@hightechlowbudgetrv6729 LOL...not to mention "damaged humans". :)
How much money can one expect to save by doing it themselves?
I am sorry, I would have no idea. For example, where we are now if I had a mobile tech come out that could do it, it is $115 per hour just to come out on site with a 1 hour min. I would have no idea what it would cost to as it would be based on how, where, etc. it would be serviced. I just knew I had the skills to be able to do it and want to show it being done just in case it helps someone else who also may be able to do it. The two fans costed $38 shipped from inverterservicecenter.com/ Actual Part Page: inverterservicecenter.com/magnum-energy-44-0004?filter_name=MAG-44-0004
And they would have charged much more for the fans too.
@@naiiawahVideo LOL...You are correct. They would need to come out to find your issue, see it is the fans, then have to likely order them and also mark them up. Thus of course charging you to come back. But again, I did feel good with my knowledge I could make the repair.
I sent mine out to Colorado turned out just the fans were needed. $665.55 way overpriced whe I should have done it myself.
So how's loki doing with training.so I tried reaching out to DogWorx no response
He is doing great! He is working hard to get his CGC endorsement & special service training. I am kind of surprised you have not heard back. Jessy is the owner...Reach out again and use our name. I would call, you would likely get voice mail and then, like we did, a text message back that they were currently in training. We started off back and forth via SMS chat.
@@DavidBott yah I reached twice to Jessy
@@george9258 When was the last time? Also is your name Geo? I can ping here as I find that strange. Did you call I take it? You can try Facebook as they are active on it... facebook.com/dogworxacademy/
Me and electricity... "no like it to muchee"....
Dave, are you ok? You seem to be trembling uncontrollably
Hi Harry....It was the meds I was on and going though withdraws. All good but I will admit, I was a little nervous when I went in to remove the screw. But the shaft I was using was electrical safe. I don't recommend doing it shaking of course. :) (Thank you kindly for your thoughts and concern.)
Absolutely flabbergasting that they did not use a three wire fan so that the unit could measure the fan speeds! Talk about penny wise pound foolish.
I had thought the same thing!!! It would be nice to KNOW OF A FAN FAILURE before you need to find out the hard way that your Inverter/Charger is overheating and need to use a flashlight to look inside it though the vent to see if they are running. In our case we would lose power and then 1 min later it would come back, and then go out again 5/10 mins later. It ONLY show the TEMPERATURE issue on the screen WHEN IT IS HAPPENING. So each time I got to the controller, it had already reset and I had not seen it. It just happened to fail when I was looking at it one time still trying to figure out what was happening. It really should have a fan sensor!
