In response to Re: Gas water heater requires reset
The gas water heater burners are not controlled by any power connection from the exhaust fan are they? The gas burners use a thermocouple which is a closed loop system which screws into the gas valve to prevent gas flow in the event of pilot out, and permits gas flow when the thermocouple is heated by the pilot, and the water temperature drops, requiring re-ignition. You seem to be describing two different (but related ) problems, unless the gas valve is interconnected with the fan controller. Thermocoulpe replacement is not terribly difficult, unless you really don't know what you are looking at. Electrical control sounds like it is outside your capacity. Do yourself a favor and call a LICENSED plumber.

: Several times each day my gas water heater goes into a mode where the exhaust fan runs continuously but the burners never come on. Powering the unit off and back on causes the burners to come on the water heats up normally. When the water cools, the fan again comes on but no burner.

: Could this be a DIY type repair?
