Atwood water heater shutting down

Recommended Posts

Hi folks,

I have a '97 Fleetwood Discovery, the water heater was replaced by the previous owner about 7 years ago.  I have recently been experiencing an ongoing issue with the water heater...

  • it will cycle as expected as long as I am using the water, shower, laundry, dishes, then after no use for a few hours (usually over night) it will shut down.  I have to fire it up by using the override switch on the control panel.


  • the water heater is overheating the water and shuts down.  I have to fire it again from the control panel.

I have had the sensors changed several times as well as the control board on the heater, several times.  We removed the Winterizing valve system.  The burner has been cleaned.


Does anyone have any suggestions on what we have missed in our diagnostics and need to change?

I agree with Carl. Now you may even buy an adjustable thermostat. Either way it must be tight against the tank and well insulated to work properly.
