We have a Class A 1999 Fleetwood Discovery. We have recently had to replace our relay transfer switch as we couldn't get our onshore power to work but the generator worked fine to power everything. Now both onshore and generator power work after replacing the switch. Prior to replacing the switch the air conditioning worked fine. After replacing the switch we are now having issues with our a/c. We are 30 amp with two roof a/c units. Electronic Climate Control box will shed until the a/c kicks on. The fans work fine on any temperature setting. The air conditioning will come on at any temperature set above 70 degrees. If we leave the a/c on above 70 degrees it will eventually go to shed after 10 minutes and the a/c is no longer working. The a/c will not work at all under 70 degrees. When I say not working it is blowing out air (fan) but not getting cold. Both a/c units (front and rear) are acting the same. I don't know if replacing the transfer switch could have had some impact on this or if this is just a coincidence that at the time the switch went out so did our a/c. We did check the a/c wires, etc. to ensure that they didn't come loose while replacing the transfer switch. Please let me know if you need additional information this is my first time posting in an rv forum. I appreciate any assistance. Thank you.
