Well good thing i checked but....., DARN!!!!!

:M. Cranked up the A/C today, just to make sure all was well... But it wasnt! It runs, blows cold air, BUT... Is making a heck of a noise almost sounds like something in the squirrel cage fan... So up on the roof i go, after taking it apart, and looking at it, checking it, etc.... I turn it back on without the shrounds on either fan and it is still making noise.. Sounds like it is either the motor losing a bearing, or the compressor making a racket.. But either way, i am going to get it fixed before our trip to florida this sept. The unit is the original that came with the coach. A Carrier 15,000 BTU ducted with a remote control unit. I checked and i know they no longer make this unit, but there is a conversion kit for a coleman unit that allows me to keep the original grill, and the remote. YAY!! Better than that is my extended warranty covers the A/C unit (per my paperwork and contract i have on file ) with a $50.00 Deductible :B. ... Now, the bad part is having to try and get a appointment to get the rig in. I bet that they are doing a lot of A/C units seeing how its July..... I wonder how many weeks they are behind.... :h

    Yep, already did. Cleaned them, checked them, etc.. No cracks, missing baldes, nothing.... No cracks in the squirrel cage fan, or the other one for the back. I actually had it running without either of the shrouds on so i could see just here the noise was coming from, and it is right at the motor. But the compressor is also right next to the motor so it could be either one, hard to tell without a stethoscope. But im guessing that with a 11 year old coach, im guessing the A/C is the same age, and the fact that they no longer make the A/C unit, it will be a replacement job. But will call the warranty company monday when i get to the RV dealership where i bought the coach and get everything set. I dont take chances, and like having both parties repair place and warranty company on the same page. And of course i get everything in writing!

    I had a blower motor that the bearings went out last year. It sounded like some one torturing cats on the roof. I changed the motor with one I bought on Amazon and it works great now. I was able to get some light oil into the bearings and it helped for a while.

    Tried some oil too... No good. I am just stumped as to the sound, i could have put money down betting it was a stick or something rubbing in the squirrel cage fan. But when it still did with both front and back shrouds removed, there is only 2 other moving parts... Motor and Compressor...

    As Mandalay Parr says try the fan only and if noise persists, try the compressor without the fan. That is, unless you're dead set on buying a new unit and don't care about spending the money.

    didn't check without the compressor off, but I figure with a 50.00 ded, and because they don't make the unit any longer. I'm figuring they will just replace the unit, which is fine with me. I would rather have a new one than a 11 year old one

    Check to make sure the squirrel cage fan is tight on the shaft. I had a squirrel cage that broke loose from it's mounting on my home furnace. Thought it was a bad motor capacitor. When the motor got up to speed the cage could not and it made a he11 of a racket.
