International Comfort Products PGF036H100F Defrost Sensor Board
The defrost control board determines when to initiate an important defrosting cycle if necessary, to get rid of the frost that collects on the outdoor unit. The defrost board relies on a sensor located near the condenser to verify when to initiate the defrosting cycle.
Key indicators that my International Comfort Products defrost sensor board is not working properly?
- The main circuit board may show an error code produced by too much frost
- The defrost feature does not begin even though there is quite a bit frost on the external unit
- Your system could not run because of lack of airflow through the outdoor unit
