International Comfort Products HHP218GKA1 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin an important defrosting cycle which actually helps to remove frost build-up that may accumulate. The control board relies on a sensor located somewhere by the condenser to make the decision on when the defrost cycle should begin.
Elements of a defective defrost board
- The main circuit board could throw an error signal when encountering a problem
- Self defrost sequence will not initiate despite the fact that there is quite a bit frost on the unit
- The whole system may not run for the simple fact of the amount of frost on the outdoor unit
