International Comfort Products T9MPV050F12B1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin an important defrosting cycle which may be needed in order to defrost your outdoor unit. The board looks to a specific sensor which is near the condenser somewhere, in order to make the decision on when the defrost cycle should begin.
