International Comfort Products PGME48G0905 Defrost Sensor Board
The defrost control board determines when to initiate the defrost cycle which may be necessary to remove frost build-up that may accumulate. The defrost sensor board depends on a defrost sensor located somewhere by the condenser to decide when to begin.
What red flags are there that my defrost board needs replacing?
- The HVAC system control board may show an error of some type if the defrost control board fails
- Defrost mode does not run even though there is a lot of frost that makes the unit run like crap
- Air conditioning may stop operating at all because of too much frost
