Squeaky Coleman Mach AC

Our 2016 Jayco has a 15K Coleman Mach ac unit that started to whistle/squeak on our last outing. It was intermittent but annoying. I contacted a Mobile RV tech that was not able to meet up with us, but he told me that the blower motor bushings are the weak link on the Coleman Mach units. He suggested that I lube the front bushing and that might help for a while. Well, after many tries and a 90 degree bent straw I was able to shoot some WD40 onto the bushing. It did quiet it down and it ran ok for the rest of the trip. I checked on line and the replacement motors are over $100.00.

Anyone have a similar experience? and what was your solution...
  • I just went through a similar experience with my 2013 Jayco and Coleman Mach. The motor in mine had sealed bearings and not bushings. I bought a replacement Fasco brand motor from Amazon and then replaced the bearings on the original motor. The only issue I had was getting the correct bearings - mine were a metric bearing with a 1/2" bore, Non-Standard. Ordered some from China and they fit fine.

    If you are handy, you might take out the motor, and verify the bearing condition and p/n - put it back together while you order some bearings.

    Let me know if you need more details about my efforts. Happy to share.
  • The bearings are failing. Bet that W. W. Grainger or another local place that sells motors can beat that price. Just give them the specs off the motor label.
