Carrier 38TPA060 Defrost Sensor Board
The defrost sensor control board controls if and when to commence the defrost sequence which helps to remove frost build-up that may accumulate. The board relies on a specific sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Simple indications of a dying Carrier defrost sensor board
- Defrost mode never initiates even though there is a large amount of frost on the unit
- The control board might issue an alphanumeric error code when the defrost control board refuses to initialize properly
- The system will end up not running for the simple fact of too much frost
