Description
The York S1-33103012000 Furnace Control Board Replacement Kit is an electronic operating part used to regulate heating and blower cycles in HVAC furnaces. It is a two-stage system that receives signals from the thermostats, sensors, and safety parts and controls ignition and fan speeds. It is installed in the furnace control compartment to replace the original controller to enable the system to respond in a coordinated manner. It is the logic that orders heating steps, and turns the blower on and off. It keeps safe and reliable temperatures during heating cycles.
