Description
The Lennox 52M46 Control Board is an essential part of your Lennox HVAC system as it is an ignition control board. When your thermostat detects a heat demand, the control board takes center stage. It regulates the gas valve and introduces itself to open up and allow the gas to go to the burner. Subsequently, the gas is ignited with an igniter, and a flame is observed to approve its burnout. If the flame is not detected, the Lennox 52M46 Control Board shuts off the gas to prevent leakage or an explosion.
