15-Year-Old Gibson Furnace – No Heat / Flame Dropout Client reported no heat due to the flame dropping out almost immediately. Removed and polished the flame rod and checked all electrical connections. After cleaning, the furnace is operating normally and the flame is holding. Completed a full safety check and diagnosis with no issues noted. Recommended replacing the flame rod as a preventative measure, but cannot guarantee the longevity of other components given the furnace’s age. Client will monitor, and if the issue returns, the flame rod and/or circuit board may need to be replaced.
