Goodman GDH80904BXCA Defrost Sensor Board
The defrost sensor board controls when to launch the defrost sequence which actually helps to keep the outdoor unit free from frost build-up. The control board is influenced by a defrost sensor located somewhere by the condenser to determine when the defrost cycle should begin.
Major clues of a barely functioning outdoor defrost sensor board
- The system may stop functioning due to the fact of the amount of frost on the outdoor unit
- The HVAC system control board could display an alphanumeric error code when the defrost control board refuses to initialize properly
- Defrosting never starts even though there is excessive frost on the external unit
