Then HOLD DOWN BOTH the zone and mode buttons AND while you are holding them BOTH down you turn it back on. "FF" should appear on the control and then you let up BOTH buttons and it should work again. we also found that we must have both front and back AC units on the same fan setting. Low, High or Auto. One AC cannot be on low and the other on auto. Thanks for the reply. My reset steps wer ea little different, but I looked them up and reset it. Unfortunately it did not help. Thanks again through!

I would hope the dealer that installed the 3rd AC would not have done so if it could not handle it. They were also the ones I bought it from. So I need to figure out the load pull from each AC, to see if it can handle it. If it could not handle it, what would be the side affects? (how would the generator react?) Would it over load the generator and blow a breaker on the whole thing? Would other damage could it cause? I could not find any fuses blown or breakers thrown. Thanks for your input. GeraldA/C E7 Error codeHello all, I have an a/c problem and of course it happened on the weekend when my dealer is closed. Luckily I am just at home getting ready for a trip next week. Here is the background. I have a 2012 Voltage 3200. This winter I had a 3rd AC installed in the garage. I have dometic thermostat 2 zone controlling bedroom and living room and the 3rd is controlled on the unit. I brought it home from storage (kept in a covered storage) and started it up, running generator power. I turned all 3 ac units on and left for a while. I returned 30 minutes later and the living room ac and garage ac where off. My thermostat is giving me an E7 error code, which means loss of power to the unit. I checked my inside breaker box and no breakers or fuses where tripped. I have turned it off and left it for a day and tried it again and it won't come back on. Another curious thing is that my microwave won't come on either. I am not sure if it is related or if I just had not noticed before. Is there another breaker or fuse on the outside for the AC? Any suggestions? Thanks Gerald
