International Comfort Products HAC260GKA4 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost sequence which assists to keep your outdoor unit from plugging up. The control board depends on a specific sensor located near the condenser to agree when to initiate the defrosting cycle.
What to see if the defrost sensor board is in need of replacing?
- The main control board could display an error code when the defrost control board refuses to initialize properly
- Self defrost sequence will not initiate despite the fact that there is quite a bit frost in the way
- Most systems will stop operating for the simple fact of the frost issue
