Lennox 27M25 Motor Harness 5 Pin

The Lennox 27M25 is a Motor Harness, a part that seems to be a minor yet significant part of the HVAC system. This 5-pin wire harness serves as a group of circuits of wires where each wire transmits particular signals. It acts as a link between the motor that controls other operations in the HVAC system and the control board that is the central nervous system of the system. Through switching on and off the control board communicates to the motor the speed it needs to run at, when to start or stop, or even how to modulate depending on heating or cooling needs.
