Does the microwave and the rear TV work? Both TVs and the micro go through the inverter even when on shore power, the inverter has a built in transfer switch.
If the rear TV and micro are not working there is a circuit breaker on the front of the inverter. (should be located 2nd compartment back, drivers side) it is attached to the floor of the coach.
I would definitely turn the breakers on and off to be sure they are reset properly. They should be the ones closest to the bathroom.
If you want to remove the relay on the back of the front TV outlet the directions are on this thread.
