Lennox 33F37 Flame Sensor Els PW 17895 ensuring the circuit interrupts beforeThe Lennox 33F37 Flame Sensor is a critical OEM replacement part engineered to maintain the safety and operational sequence of residential gas furnaces. As an HVAC flame rectification probe, it generates a microamp signal to the furnace control board upon detecting heat, ensuring the gas valve remains open only when a pilot or burner flame is present. This high integrity sensor is functionally identical to part 33F3701 and serves as a direct
