duo-therm a/c does not start
I just returned from a trip and the whole time I was on 50A shorepower the front A/C worked on the thermostat settings. When I went to leave I turned off my A/Cs before unplugging the cord. After starting the GEN and power came on I turned them back on but the rear came on after the short delay but the front never did, nor the fan on manual setting, even after a 5 hour drive and the stat dialed down to 68*, but it was well above that temperature. These are both Duo-Therm units. The front A/C breaker was not tripped and I have a 50A GEN so I am stumped as to what could cause it to work on shore but not GEN. I don't have 50A at home so I can't test it here that way. Where do I start to diagnose? I have another trip planned and reserved in two weeks and getting in an RV shop won't happen for at least 30 days by which time it won't be needed.
