or can no longer satisfy the millivolt requirements of the thermocouple despite proper gas pressure

This is a 2-pole heat sequencer

a terminal cover to prevent accidental contact with live high-voltage connections

ensuring it stands up to the vibration and thermal cycling of commercial refrigeration and A/C units

Key Benefits Precise 280-Degree Calibration: Ensures the system shuts down immediately upon detecting a thermal spike caused by restricted airflow

Lennox 14K99 Electrode-Ignitor or can no longer satisfyThe Lennox 14K99 Electrode Ignitor is an essential OEM component engineered to maintain precise spark ignition sequences in high performance gas furnaces. As a high voltage furnace ignitor replacement, this part is built with a heavy duty ceramic insulator and a durable metal alloy probe to withstand the extreme thermal stresses of the combustion chamber. When a gas furnace won't light, a fouled or cracked electrode is often the culprit, leading to
