A/C wiil not Run on Auto A/C 
I have a 1998 Fleetwwod Pace Arrow. I have 2 A/C units on it. One will work when put on Auto Cool and the other will not when on Auto Cool. The one that will not will not even turn on at all. It will blow on High Cool but not cold air. I can switch the side the units are pluged into at the control unit on the wall that controls both units but each has a sepearte control on it and then it will do the same to the one I plug into the one side of unit.

I have bought a new wall control unit and it does the same thing. What can it be that causes this?

Do you have 30 or 50 amp shore power? Have they ever both worked at the same time?
Will they run with generator power?

Re: A/C wiil not Run on Auto A/C 
I have 30 amps. Yes they both use to work fine. My M/H does have the power saver as the one above said as in if both A/c'S tried to come on at same time they only one would as it sheds power.

The issue I have is that the Front compressor will not cut on one unit when you put it on Auto A/C on the Control but then if you switch how they are plugged into the wall control unit then the Front one will come one and the Back one will not.

If you only have 30 amp service in your MH only 1 A/C will run at a time. Several posts here on how to make a "cheater" to get both A/C unit to work when the MH is wired for 30 amp service.

I have a 2003 Bounder with 30AMP service, I can run both A/Cs at the same time, however if both are initally turned on at the same time the EMS will usually allow only one to start then after a few minutes the other one will start However if much of anything else is on (consuming power)the EMS will shed one.
