Keystone Outback Bumper Pull '09-Water Heater Issues-Help

[Bella222]

What causes the 6 gallon water heater to shut off and relight multiple times ? The furnace works perfect. Propane tanks are full. Thx for any help.

Be sure it's full of water. If it's full of water, then it could be the thermal sensor that is positioned in the flame. It's supposed to send a signal to the control board that the flame is burning. If the connection or the sensor is bad, it will do as you describe. What brand of water heater is it? Many documents available online to aid in troubleshooting.

Well, it is supposed to shut off and re-light under thermostat control. Are you saying it happens more frequently than you think it should? That could be a faulty thermostat, or the main thermostat is stuck in the closed position and the ECO (basically a back-up thermostat is controlling the heating. That will result in a continuous cycle of on/off, never staying off for very long. And the water at the faucet is probably unusually hot as well, since the ECO allows a 20 degree higher water temperature.
