D&J Posted April 11, 2021 Report Share Posted April 11, 2021 Start by looking at the blower motor to see if it's spinning free. Denny Quote Link to comment Share on other sites More sharing options...

I looked through the YouTube RV Air Conditioner repair video list and didn't see any that listed your problem but you might want to see what you can find. There are too many to watch them all.

TXiceman Posted April 11, 2021 Report Share Posted April 11, 2021 It may be an interior duct lining in the blower section that is loose and vibrating. I had this happen to both Carrier units on my Cameo. Ken Quote Link to comment Share on other sites More sharing options...
Jinx & Wayne Posted April 11, 2021 Author Report Share Posted April 11, 2021 Thank you for the manual and ideas. The issue appears a bearing in the compressor. We've done a cost benefit analysis and decided to replace it. It is 16 years old and Carrier is no longer in the RV A/C business. If this bearing is going we don't want to put more money into the unit. So I'm starting a thread on recommendations.

I think that I would do the same as you could pour a lot of money into it and you would still have a 16 year old a/c. Quote Link to comment Share on other sites More sharing options...
