On your model Atwood I believe all the 110V hardware is on the back of the hot water heater (element and thermostat). I am fairly certain the 110V element has its own thermostat and ECO switch similar to a residential hot water heater. The ECO switch and thermostat on the front of the unit only controls the 12V propane side of the heater. Likewise the circuit board is 12V only for the propane side of the heater. Before pulling the water heater out to access the back have you verified that your 110V source into the heater is functioning (110V breaker is on, switch to the electric element is on)? Some heaters have a 12V switch in the RV that fires a solenoid to energize the 110V side of the water heater, if there is not power to the solenoid or the solenoid is bad you will not get 110V power to the water heater.
