Lennox 10D08 Defrost Sensor Wire Harness

The Lennox 10D08 Defrost Sensor Wire Harness is an essential component in your Lennox heating and cooling equipment, used only during defrosting cycles. It identifies the presence of frost on the outside coil during cold climate operation. This buildup can lead to a decrease in the amount of air which flows through the tubes and, decreases efficiency. The harness links the defrost sensors to the control board of the unit. If frost is sensed, the control board triggers a defrost mode that clears the ice and keeps the system efficient. The wire harness is about 50 inches long and can be used with a number of different Lennox heating and cooling systems.
