Description
The Trane CNT4363 Defrost Control Board is an electronic that is specifically manufactured for Trane heat pumps. This is an essential part, which is slightly less than 5 inches in length, controls the defrosting process. The CNT4363 detects the formation of frost through the temperature sensors placed in the outer coil of the evaporator. In this state, a frost build up signal is produced by the board to produce a defrost cycle which in turn reverses the flow of the refrigerant to melt the ice. The result of this is the prevention of formation of exorbitant amounts of ice at the coil and thus minimization of obstruction of airflow and heat pump efficiency. The Trane CNT4363 maintains your Trane heat pump’s outer coil from frosting over, thereby maximizing its efficiency and effectiveness.
