International Comfort Products HAC036GKA4 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrosting phase which may be necessary to get rid of the frost that collects on the outdoor unit. The board looks to a temperature sensor that can be found near the condenser, in order to agree when to initiate the defrosting cycle.
Major clues your International Comfort Products defrost sensor board is in dire straights
- The defrost feature will not kick in despite that there is a large amount frost on the outdoor unit
- The main control board could display a specific error code when the defrost control board refuses to initialize properly
- The whole system may stop working due to the fact of way too much frost build-up
