Carrier 58DLX04510008 Defrost Sensor Board
The defrost sensor control board controls when to launch the defrost sequence if necessary, to get rid of the frost that collects on the outdoor unit. The defrost board relies on a specific sensor located near the condenser to verify when to initiate the defrosting cycle.
Subtle cues of a defective Carrier defrost sensor board
- Defrost session never initiates despite the fact that there is quite a bit frost on the unit
- Your main control board could display an error signal referring to a bad defrost board
