The only tool you need to replace a thermocouple is a wrench.

Consequently, how does a thermocouple work in a gas fireplace?The thermocouple on your gas fireplace is a heat-sensitive device that keeps the pilot gas tube open while the pilot is lit. It does this by generating a small electric current — on the order of 10 to 30 millivolts — as a signal to the gas valve.Beside above, how long do thermocouples last? Thermocouples can last several years, but they don’t typically last as long as the furnace itself. If the pilot remains lit, but the main furnace doesn’t stay lit, it’s time to replace the thermocouple. Also Know, where is the thermocouple located on a gas fireplace? The thermocouple is a gas furnace component located near the pilot light burner. It is a safety device that shuts off the gas if the pilot light goes out or the electric igniter fails.How do you know if you have a bad thermocouple?If you can’t get the flame to light at all, and you’re sure the gas is on, there’s probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that’s the sign of a thermocouple malfunction.
