My A/C in my class A RV was working great yesterday now the fan and compressor run but no cool air. It is not frozen up, I have cut the unit off for several minutes and restarted. Any ideas?

Hello jsd3024,

Welcome to iRV2, we're really glad to have you here as a new member and are looking forward to reading your posts about your RVing experiences and adventures in your class A motorhome. You'll find a great bunch of folks on this site who are very knowledgeable of RVing, the rigs we use, and the places we go in them.

There are several things that could cause your AC to not cool while the compressor runs. Some are: <UL TYPE=SQUARE><LI>Low freon.
<LI>Bad compressor.
<LI>Restriction in refrigerant line.
<LI>Low air flow over evaporator coil (dirty filter).[/list]
I'm sure there are others, these just came to mind. As you'll soon see, others will be eager to help and share their ideas.

Again, welcome to iRV2, we're glad you joined.

jsd3024, again welcome to iRV2.com. We are glad to have you join us here. Sorry to hear that the air conditioner has went south on you. By chance is it a heat pump? If so, it may be a stuck reversing valve. Do you have a clamp on amp meter? If so check the amperage of the circuit feeding the air condiioner at the circuit breaker and let me know what you find.

Not a heat pump. I may be able to get a clamp on meter, what should it be?

If it is a 13,500 btu your amperage draw should be in the 12 amp range. This will vary depending on the actual voltage. If it is low on freon then the amperage will be low too.
