Carrier 48JZ060130300 Defrost Sensor Board
The defrost control board controls if and when to commence an important defrosting cycle which actually helps to defrost your outdoor unit. The defrost board depends on a sensor located near the condenser to agree when to initiate the defrosting cycle.
What to see if the AC defrost sensor board is on its last leg?
- Defrost mode has not run for a while especially when there is frost that makes the unit run like crap
- The main board might issue an alphanumeric error code produced when the defrost board is bad
- Your system could stop working for the simple fact of frost blocking the fins on the outside unit
