be sure to let us know what it turns out to be. That way we all learn something plus anyone searching the forum in the future with a similar problem.

Yes, thermostat is working properly....we actually have two--front and rear.

My convertor was bad. Once it heated up, it was going to low voltage--9.5-10.5. Checked at both the convertor and the fuse panel. He replaced it, then checked again and with all the lights and AC on and it was only down to 12.03 then turned everything off and back up to 13.6. I hope I got those numbers right.

But the gist of it, it was low voltage issue from a 'dying' convertor. It would function okay, but was overheating with continuous draw of the AC.

$452 repair including labor, and then I had him also check the AC units physically as well and they are fine and the fans and compressors are working properly. Then an additional $100 for an awning repair that I needed done anyway, and was very glad he could do while he was here!!

Though......................I want to say some nasty words now.................the unit just shut down again. UGH! Calling him again.

Not sure how DC voltage drops would cause an issue with the air conditioner as the air conditioner is completely 120v AC. Now I'm not saying your converter didn't need work/replacement, but it should have no impact on the air conditioner. At least I don't think it would.

On my rig, a Fleetwood Expedition, you need 12 volts for the controls to the thermostat to make A/C work. . .

Yes. I have an Intellitec EMS and it needs 12V to operate the system. Tech is back...appears to be that is my current issue. Intermittment 12v power to the EMS.

I had some work done on my battery disconnect switch before I left town originally, and I'm now wondering if they might not be related.

Another update. After being on indefinite hold with Intellitec, seems that my EMS is no longer made and there are no parts for it. So, tech is going to have to hard wire and we'll just have to use thermostats instead of the EMS. I told him it didn't matter to me so long as have cold air!!! LOL

Well your not going to have cold air when it gets hot outside till you clean out the dirt in the condenser on the A/C

If your humidity is high I would suspect the evaporator is freezing up. Try running the fan on high and fan only for a while. If it begins to cool again after this you are building ice on the coil. I like the quiet of a low fan speed but in humid conditions it takes a higher fan to move enough air to prevent freezeup.
