International Comfort Products CHP218GKA1 Defrost Sensor Board
The defrost sensor board will determine when to initiate the defrosting phase in order to remove frost build-up that may accumulate. It is relayed information from a specific sensor located somewhere by the condenser to determine when the defrost cycle should begin.
How do you know when your AC defrost sensor board is in need of replacing?
- The defrost sequence will not kick in even though there is a large amount of frost that makes the unit run like crap
- Most systems will not operate at all because of the fact that there is too much frost
- The HVAC system control board may show an error of some type produced when the defrost board is bad
