For the electric switch - it sends a 12 volt signal down to a relay on the back of the water heater letting the 120 volt current from the water heater circuit breaker go to the water heater. The electric thermostat also controls the relay. Unless you are an electrician, best to leave the trouble shooting to the experts other than checking the 120 volt circuit breaker. As for the propane - The switch sends power to a circuit board which controls the water heater. About all you can check is the 12 volt fuse and making sure the propane is on. If the coach has been stored, you might bleed the propane line. Make sure the propane is on and light the stove for about one minute, that will get most of the air out of the line.
