Air Conditioner For JAYCO 2000 Class C Motorhome.

Question: Recently my air works on and off.I turn it on, sometimes it works sometimes it doesn't. Last night I turned it on, it did not work, my husband took his fist and gave a pound to the area in the ceiling and poof! The air came on. Last time it didn't work I got disgusted and slammed the door to the rv...poof! the air came on. Sometimes if we move the unit it will come on afterward.
Sounds like a loose wire/connection but where do i look?
Thanks!

Robbie: Most of today's air conditioner units have a small computer in them with circuit relays, called a PC Board. When they start sticking, you can hit the computer or the ceiling and they will start working. Even slamming the entry door can do the trick. I really don't think you have a loose connection but anything is possible. I really don't advise you opening the system to check the wiring, but if you do, be sure all power is off. When you access the PC Board, look for a burned connection or a connection that is loose in any way. If the problem is a relay sticking, you'll have to replace the PC board.

If you have any doubt in your abilities, please have a qualified tech do the testing for you.

Let me know what you find,
Robbie
