International Comfort Products GNE100F20A1 Defrost Sensor Board
The defrost control board instructs the system to activate the defrost cycle which aids to get rid of the frost that collects on the outdoor unit. The defrost sensor board is influenced by a temperature sensor located near the condenser to determine when to begin.
How do you know if your outdoor defrost sensor board is about to stop working?
- Your system could not run due to the frost blocking the flow of air
- Self defrost sequence never runs especially when there is a rather large amount of frost that has built up
- Your main control board could display an error signal referring to the failed defrost sequence
