Question about Water Water Heaters
The heater didn't reach the high temp by itself, this heater is used as backup for an outdoor wood burner. During the worst of winter it did see water above 190 degrees. Can the error be cleared without replacing the gas control valve/thermostat as the manual indicates?
I wouldn't think that sensor would trash at 190 but if the manual says overheated sensor--I'd go with that and replace it providing it's not an exotic priced sensor---the sensor as far as I know should be independent from the gas valve but since I don't know what make/model/type/age of unit my answers are generic good luck Happy Rabbit

1. Check red wire connections at hot water temperature sensor.
Clean terminals with an eraser. If badly corroded, replace sensor
and wire harness. See Fig. 65, page 48.
2. Sensor may trip if water temperature drops below freezing to
protect heater from freezing conditions. Any damage due to
freezing conditions is not covered under warranty.
3. Clean inlet filter screen and clear any debris out of shower
heads, faucet aerators and whole house filters.
4. In areas where water has a high mineral content, periodic
descaling may be necessary.
I would be very surprised if your water temp is below freezing, even in Alaska, check it with a thermometer. Well water is usually around 45 degrees F.
