Changing Thermocouple On A Fireplace
If your gas fire isn’t working properly and goes out too often you probably need to change the thermocouple – a small device that shuts down the gas supply if the pilot light goes out.
How to Replace the Thermocouple
- Turn off the gas and make sure the pilot light goes out.
- Wait twenty minutes for the thermocouple to cool down.
- Loosen the screws that hold the thermocouple in place.
- Pull the thermocouple out with long nosed pliers.
- Put the thermocouple on a surface that will not burn (just in case).
- Clean the screw terminals.
- Insert the two wires of the new thermocouple and tighten the screws.
- Turn on the gas and re-light the pilot light.
- Wait a while and then turn on the fire. If you have replaced the thermocouple correctly the fire will light.
- Thermocouples need to be checked regularly but replacement is the only option for repairs.
