International Comfort Products PGME36G0904 Defrost Sensor Board
The defrost sensor board controls if and when to commence the defrost cycle if necessary, to rid your unit of frost that can build up. The control board is relayed information from a temperature sensor that can be found near the condenser, in order to make the decision on when to begin.
Chief elements of a poorly performing International Comfort Products defrost sensor board
- Most systems will not operate due to frost blocking the fins on the outside unit
- Defrosting does not run even though there is quite a bit frost that makes the unit run like crap
- The main board may signify a type of error code when the defrost board fails
