How do I know if there is a problem with the pilot light?

If you suspect that there may be a problem with the pilot light, you should follow these steps: First, make sure that the gas valve to the fireplace is turned on.

If the pilot light is not lit, try lighting it according to the manufacturer's instructions. This typically involves pressing and holding down a button or switch while lighting the pilot light with a match or lighter. If the pilot light will not stay lit or if it appears to be burning abnormally, there may be a problem with the pilot light or the thermocouple.

If you suspect that there may be a problem with the thermocouple, you should follow these steps: First, make sure that the gas valve to the fireplace is turned on.

To test the thermocouple, you can try turning off the gas supply to the fireplace and then turning it back on after a few minutes. If the pilot light stays lit and the main burners come on, the thermocouple is likely functioning properly. If the pilot light goes out and the main burners do not come on, the thermocouple may be faulty and should be replaced.
