International Comfort Products PGC060K100A Defrost Sensor Board
The defrost sensor board determines when to initiate the defrost sequence which aids to get rid of the frost that collects on the outdoor unit. It depends on a temperature sensor that can be found near the condenser, in order to decide when the defrost cycle should begin.

- Unit defrost session has not run for quite some time even when there is a large quantity of frost in the way
- The main control board might give out an error code referring to a bad defrost board
