International Comfort Products NTC5125BKD1 Defrost Sensor Board
The defrost sensor board controls if and when to commence the defrost cycle which aids to rid your unit of frost that can build up. The board is relayed information from a temperature sensor which is near the condenser somewhere, in order to make the decision on when the defrost cycle should begin.
General indicators that your your outdoor defrost sensor board needs replacing
- Air conditioning may cease to function due in part to the frost blocking the flow of air
- The defrost feature does not begin even though there is a large amount of frost in the way
- The main circuit board may show a specific error code produced when the defrost control board fails to receive a signal
