Where is the thermocouple located on a gas fired water heater?

Remove access covers as needed: on a gas fired water heater you will need to remove the manifold door at the heater bottom in order to access the end of the thermocouple that mounts on and monitors the pilot flame. On a gas-fired furnace you may need to remove first the furnace cover and then a flame shield. Keep any mounting screws for re-use.

When to replace a thermocouple or thermopile sensor?

When replacing a temperature sensing device like a thermocouple or thermopile, you should be sure to purchase the proper part. Thermopiles are made by combining multiple thermocouples together in series in order to produce more electrical current than a basic thermocouple. Externally a thermopile still looks like a single sensing device.

Can a bad thermocouple stop a gas boiler from working?

A bad thermocouple itself can prevent a gas furnace or boiler from working – if you can light the flame at the pilot manually but then the flame goes out when you release the manual gas feed valve, the thermocouple is probably bad.
