Excellent job. The consumer should never have to do all this. Shame on Maxx Fan. They need to go back to the drawing board and re-design their product to make it reliable.
U kidding me.. I maxxfan deluxe is only a few months new and it’s beeping every 5 seconds and then reversing. Strange right? We put electrical liquid tape on the board before install.
Sorry to hear your trouble and I didn’t expect this to happen as well. Write to maxx air and send them your serial number they will send you a new board and motor. I also made a small hole to make sure condensation does not sit up there. Here is my fix video. ruclips.net/video/6k0mPqCgrl4/видео.html I have not had any problems since my fix
Half this video is completely unnecessary! You do need to go up top at all. The board is accessible from inside. You even expose the same part of the fan when you are below. Just drop 4 screws behind the vent and the one holding the knob in (pull the knob) and the board is accessible from inside the van. Never cut both conductors at the same time. Cut one, move it aside, cut the other. That way if you are completely wrong about your assumptions and are cutting a live circuit you don't short it and damage things.
The reason your fan was beeping was because of excess voltage. Do you use a lithium battery? The board on the fan can't handle the higher voltage of lithium batteries. If your fan hasn't given you problems since this fix, your lucky. Install a DC to DC converter to the power in on the fan so it only gets 12v.
These lifepo4 batteries max at 14.4 which is lower that he alternators voltage output. Each lithium chemistry can have a different voltage output but come on this is an inherent defect.
After 2 blown PCB and a blown motor, I finally put a dc to dc voltage regulator on it. They say they fixed it, but I doubt it. The fan is a great idea, the company is junk though.

Chris, thanks for the feedback and yes the fan was a pain in the a**
Hi, I have the same issue on my fan ! How did you get a new circuit board ?
Thanks a lot,
Hugo
Sorry for the late reply! did you find a solution?
Is there any reason I can’t replace the board with a double pole double throw center off switch so I don’t have to do this over and over again?
I don't see any reason why not but you would need to modify. send me a video when you do.
I have fitted s DC to dc voltage regulator and I still have the iss
Yeah this fan has this issue, replace the board.
Thanks for informative video. Mine is beeping as well....but out of warranty.
I would email them and send them your serial number and request that they help you as this is an inherent defect. Keep me updated.
Really good video. Thanks
Good to hear and thank you for the great feedback.
Awesome video! Thanks
I appreciate your feedback !
Anyone know how to disable the beep permanently?
Thank you for your feedback, much apprecated!
How many times are you going to say (go ahead)
U kidding me.. I maxxfan deluxe is only a few months new and it’s beeping every 5 seconds and then reversing. Strange right? We put electrical liquid tape on the board before install.
Sorry to hear your trouble and I didn’t expect this to happen as well. Write to maxx air and send them your serial number they will send you a new board and motor. I also made a small hole to make sure condensation does not sit up there.
Here is my fix video.

You do need to go up top at all. The board is accessible from inside. You even expose the same part of the fan when you are below. Just drop 4 screws behind the vent and the one holding the knob in (pull the knob) and the board is accessible from inside the van.
Never cut both conductors at the same time. Cut one, move it aside, cut the other. That way if you are completely wrong about your assumptions and are cutting a live circuit you don't short it and damage things.
Thanks for the feedback

If your fan hasn't given you problems since this fix, your lucky. Install a DC to DC converter to the power in on the fan so it only gets 12v.
These lifepo4 batteries max at 14.4 which is lower that he alternators voltage output. Each lithium chemistry can have a different voltage output but come on this is an inherent defect.
After 2 blown PCB and a blown motor, I finally put a dc to dc voltage regulator on it. They say they fixed it, but I doubt it. The fan is a great idea, the company is junk though.
Thank you for sharing, sorry to hear that your had to replace two boards.
What was the point of replacing a perfectly good working motor? If it ain't broke, don't replace it!
Sorry for the late reply! did you find a solution?
I couldn't take any more "go ahead and...." so I stopped watching.
Thank you for the feedback
