International Comfort Products H8DNL100F14B1 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrosting phase which actually helps to rid your unit of frost that can build up. The defrost sensor board depends on a defrost sensor located in the outdoor unit to decide when the defrost cycle should begin.
Elements of an inadequate AC defrost sensor board
- The HVAC system control board may issue an error of some type produced by a bad defrost control board
- Defrosting does not begin especially when there is a rather large amount of frost in the way
- The HVAC system could stop operating because of the safety issue that the frost poses
