Goodman GPC1336H21A Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost sequence which actually helps to continue normal heating and cooling operations. The defrost board is relayed information from a defrost sensor that can be found near the condenser, in order to decide when to initiate the defrosting cycle.
Main clues your Goodman defrost sensor board will eventually need to be replaced
- Defrost session never runs especially when there is a rather large amount of frost on the unit
- The primary control board could signify an alphanumeric error code when a defrost board fails to initialize
- The system may not operate due to lack of airflow through the outdoor unit
