International Comfort Products HHP230GKA1 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrosting phase which actually helps to continue normal heating and cooling operations. The defrost board looks to a sensor which is near the condenser somewhere, in order to decide when the defrost cycle should begin.
What to see if the defrost board is on its last leg?
- Your main control board may issue an error code produced by a bad defrost control board
- Your HVAC system will not work for the fact of too much frost
- The defrost sequence does not run despite the fact that there is quite a bit frost on the external unit
