Carrier 58MSA060 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrost cycle which helps to remove frost build-up that may accumulate. It relies on a sensor located in the outdoor unit to decide when to begin.
Cues of a weak defrost sensor board
- Your main control board might give out a particular error code when the defrost board fails
- Defrosting never kicks in even though there is quite a bit frost that makes the unit run like crap
- AC and heating system could stop operating for the simple fact of frost blocking the fins on the outside unit
