Goodman GHS80905CXCB Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrosting phase in order to keep your outdoor unit from plugging up. The defrost board looks to a specific sensor located near the condenser to verify when to begin.
Indications of an inadequate outdoor defrost sensor board
- The main board could display an error number if the defrost control board fails
- Defrost mode will not kick in especially when there is a rather large amount of frost on the outdoor unit
- Most systems will not run due to the fact of frost blocking the airflow outside
