International Comfort Products PGF048L120F Defrost Sensor Board
The defrost control board will begin the defrosting phase which may be necessary to continue normal heating and cooling operations. The control board looks to a defrost sensor located somewhere by the condenser to verify when to initiate the defrosting cycle.
General indicators that your your defrost board will not live much longer
- The control board might give out an error code if the defrost board goes out
- Defrost mode has not run for a while even though there is quite a bit frost that makes the unit run like crap
- The whole system may end up not running due in part to frost blocking the fins on the outside unit
