squiredude Report post Posted April 10, 2019 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. OR 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? Share this post Link to post Share on other sites
manholt Report post Posted April 10, 2019 Is it a gas/elect or just gas? What make, 6 or 10 gal. I suspect the thermostat. Share this post Link to post Share on other sites
