Then I go inside and I hear the breaker trip. I did this like 4 times last trip. I could never get the AC side to work.
If you turn on the electric right after the propane burner went off, the element shouldn't even come on, as the thermostat wouldn't call for heat since the water is already hot inside the water heater.
If the breaker to the water heater circuit (not the main breaker) is immediately tripping with hot water already, I would say there is a short somewhere between the switch and element.
