Lennox 75M31 Limit Control 320734-701 maintaining stable operation despite fluctuationsThe Lennox 75M31 Limit Control is a critical OEM replacement part designed to maintain safe thermal operating parameters within residential and commercial HVAC systems. As a primary high limit switch, this component utilizes a precise L170 40F calibration, meaning the normally closed contacts are engineered to open when the heat exchanger surface temperature reaches 170F. Once the circuit is interrupted, the burner ignition or heating source is
