International Comfort Products C9MPD075F12C1 Defrost Sensor Board
The defrost control board instructs the system to activate the defrost sequence which actually helps to defrost your outdoor unit. The control board relies on a specific sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
Hints of a failing defrost board
- The primary control board might issue an error code produced by too much frost
- The system may stop operating for the fact of the frost blocking the flow of air
- The defrost feature refuses to initiate even when there is a large quantity of frost on the outdoor unit
