Need Help With Duo-Therm Penguin Roof A/C

[Bassman]

We have been plugged in to a 30 amp RV outlet. Have been running the A/C during the day for 5 or 6 hours at a time. Just the front since we only have the 30 amp. Today, after about 3 hours, it quit running. Checked the breaker at the outlet, the one in the motor home and the fuse for the A/C controls. Still nothing. Tried the rear A/C and still nothing. Any ideas? Thanks in advance.

My buddy came over an diagnosed the problem. It was the transfer switch. Got it fixed temporarily until the new switch comes in.
