International Comfort Products PGME24G0908 Defrost Sensor Board
The defrost control board determines when or if to start the defrost sequence which may be necessary to continue normal heating and cooling operations. The board relies on a defrost sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
Subtle cues of a weakening defrost board
- Unit defrost session refuses to run even though there is excessive frost that makes the unit run like crap
- AC and heating system could not work due to the fact that there is too much frost
- The primary control board may issue a type of error code if the defrost board fails
