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...
