Customer Question

I have a Coleman Mach roof AC on my 2014 Bayhill 5th wheel. It is now vibrating and I had to shut it down. Do you have any ideas what the problem is and what to do?

Dave this is just an educated guess, but very possible the little plastic fan could have broken.Are you able to take the cover off and take a look?

It is fine with just the fan running and not cooling.

Should not be the blade then as both blower wheel and cond fan are on same double shafted motor usually. Hoe about compressor bolts.Are they secure on grommets?
