International Comfort Products PGC060H100F Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin an important defrosting cycle which may be necessary to continue normal heating and cooling operations. The defrost board is influenced by a specific sensor located somewhere by the condenser to make the decision on when the defrost cycle should begin.
Symptoms of an inadequate defrost board
- The HVAC system could end up not running due to frost blocking the airflow outside
- Defrosting has not run for quite some time even though there is a large amount of frost that has built up
- The main board may throw an alphanumeric error code produced by a failing defrost board
