  1. After installing the Thermocouple on my GTI model R-32 fireplace, the pilot light goes out when I install the front glass. What am I doing wrong

    • Hi Roger

      The most common reasons for pilot light failure after replacing the thermocouple are dirty furnace parts, faulty gas valve, defective thermocouple, improper draft positioning, and incorrect installation of the thermocouple.

      To solve the issue, first, try to find out the main culprit behind the issue and fix it by following our solution guide on Pilot Light Won’t Stay Lit After Replacing Thermocouple.

      Hopefully, you will get the solution.

      Wish you all the best.
