MaxxAir Fan Squeak Fix - Ray Outfitted How To 

V & M Great videos. do u do repairs and van builds in new york city?

Thanks for the video. I have completed this many times, but I recently did it and the motor is still squeeling slightly. Any ideas? The motor is not too old as Maxxair had sent me a new one as I had a squeel issue before. Thanks again!

I wish they would release brushless motors for these fans.

Thrilled to hear! Best wishes!

Thanks so much. Have you also experienced the MaxxAir Fan squeak?

Good luck with your repair. Let me know how it turns out!

same here... quite annoyed really seeing it cost me $550aud for it...

Running the fan on high speed will help clear out some of the brush dust from the path of said brushes, as well as sync up the grooves between the brushes and commutator. The squeaking is usually a symptom of running the fan at less than 100% speed

Thanks! Sometimes you just have to take things apart. :)

You need an imperial 3/32 Allan key. It cost £1.42 on ebay. Alternatively you can use an FCS surf fin key. That’s also 3/32. (2.38 mm)

My 2.5mm Allen key was also a touch too large, I simply filed it down a little and then it worked. I didn't have a 3/32, not sure if they exist in the UK. Hope this helps people. 🤞

@@nohandle181 :D As an engineer I can assure you, imperial Allen keys do exist in the UK. It cost £1.42 on ebay. Alternatively you can use a surfboard FCS fin key. That’s also 3/32.

Happy this video helped you. The lights were off Amazon.ca and I did not see them after the last time I looked for them. I searched for 12v puck lights to find them. I hope this helps. Happy travels 👍

Ray Outfitted ~ thank you!

It is not required to put anything on the seals. If you are having trouble getting them in then yes you could lubricate them to get them back in. The o-rings are your weather seals.

If it's brand new - run it on high for 24 hours to seat the bearings properly. 👍

Maybe the brushes needs to settle...such a shame the brushless motor is not used. Ripoff for this price. Will try to DIY switch to brushless on mine...

@@oldrichkucina8282 did you upgrade to brushless?

@@functionalvanconversion4284 Switching to a brushless motor would require an additional control board, and a 3rd wire to control the speed of the motor. It would then be running off PWM control, making it more of an AC motor vs DC. The models with a digital controller and reversing feature would add complication to retain those features. The advantage of brushed motors is they are more serviceable. But they do squeak more often when ran at lower speeds.

@@kvnhmmd thanks for the information. I only ask because all my power tools have gone to brushless, but I didn't understand that it comes with the complexity of more electronics. The squeek is bound to happen on these unless you keep HVAC filters on your windows that let the air in. Another thing I have found is to not let the screen on your max air fan be too clean all of the time (not sure why, perhaps the negative pressure or the debris collects on the screen vs the motor?).

There are some cases that fixing an imbalance in the fan blades by cleaning them will lessen or fix the noise. Happy travels 👍

A year of fan squeak? Yikes! Where in Europe? 🤔🤔

As a followup for anyone who may have a similar issue. I took apart the motor and cleaned it as described, and my fan has now been running for several hours with no squeaks :) ohhh it's blissful. 1) There was indeed some graphite-looking debris I needed to clean out, even though it was new. I wonder if it's because the graphite contacts start out flat, and quickly wear down into a curved shape against the spinning rotor thing. 2) I looked it up and apparently it's not a good idea to apply any kind of lubricant to a brushed motor. The contacts are already made of a block of lubricant.

These questions are bed directed to the manufacturer. They have voltage range specs. Check with maxxair about this but I wouldn't recommend it as you are passing through a resistor to get low speed.

My 2.5mm Allen key was also a touch too large, I simply filed it down a little and then it worked. I didn't have a 3/32, not sure if they exist in the UK. Hope this helps people. 🤞

@@nohandle181 Thanks Alex. I did manage to do it in the end the same way. I filed an allen key down until it fit. 👍

There are options for a/c if you've got the budget and/or do not intend to use it off grid. I'd love to do a video on it but first need to find the client and rig. You're looking at the very least $5k.

Oh yeah, my intention is off-grid use, without loud generators.

Yah, no problem. It's just money. 😋

HI Ray, Julie. This is something I've put a lot of thought into. I live in Texas and I am currently building out a 2018 Sprinter. For me AC in the south is a must, unfortunately all of the rooftop AC systems draw way too much power to be off the grid overnight. My solution(hopefully, will find out soon). I found a small 5000 btu window unit at HD only draws 420watts. I'll include link at the bottom. I've paired this with 600AH of 12v Lifeblue Lithium batteries(7200w). Even with the inverter inefficiency I figure this should easily run the AC system overnight. If AC compressor is cycling it won't draw the full 420W either. I plan to install the window unit under the bed in a cabinet with dc fans venting the coils underneath the van. I'll be doing the install over the next 2 weeks. Hope this helps, thanks for the video Ray! www.homedepot.com/p/Frigidaire-5-000-BTU-115-Volt-Window-Mounted-Mini-Compact-Air-Conditioner-with-Full-Function-Remote-Control-in-White-FFRE0533U1/304926708

@@RonjoV Thanks for sharing your plan. Let us know how it works. I've seen a somewhat similar approach. Best wishes!
