Carrier 58MTB100F10116 Defrost Sensor Board
The defrost sensor board determines when to initiate the defrost cycle which helps to remove frost build-up that may accumulate. The defrost sensor board is relayed information from a defrost sensor located somewhere by the condenser to agree when to initiate the defrosting cycle.
Simple indications of a dying defrost board
- Most systems will stop running due in part to the safety issue that the frost poses
- The main circuit board might issue a specific error code produced by too much frost
- The defrost feature never kicks in even though there is excessive frost that has built up
