Water Heater Repair Tutorial: Temperature Sensors ...

2019-08-27· Before you get into how to test the temperature sensor, try power cycling the unit. Put the gas control knob to the “off” position, wait a few minutes, and then try to light the pilot as normal. If the unit doesn’t come on and still codes, then you need to take the gas valve apart. Most newer water heaters use Honeywell gas valves. The Honeywell gas valve has a front, middle and back ...
