Flame Sensor Rod
The furnace utilizes flame rectification to ensure safe combustion; the sensor acts as an electrode that must maintain a clean conductive path. Over time, non-conductive oxidation and silica buildup insulate the rod, preventing the microamp signal from returning to the control board. Replacing the sensor restores the electrochemical circuit necessary for the ignition sequence to remain engaged.
