My RV AC Stopped Working After Connected To Generator

Question: Hi My AC stopped working after I connected power to my generator (1000W) and I forgot switch the AC off on the thermostat. I was able to turn it on once when I plug in to the 120 outlet, but now it doesn't work.

Thanks, Lukas

Robbie: You should never plug into power with the AC on. The 1000 watt generator is way too small to run your AC and you may have damaged the AC and/or tripped a breaker on the generator. If your AC comes on and it doesn't get cold anymore I suggest you have it checked to see if something was damaged. You may need a new start capacitor or have a burned connection. Regardless I would have a qualified tech look at it.

Thanks for the Question Good Luck,

We did not know AC was on when we plugged in power cord. When are new to this. AC was working when we left for store, but not when we returned. Can't get it running, 100 degrees outside.
