Carrier 58STA07010012 Defrost Sensor Board
The defrost control board controls if and when to commence an important defrosting cycle in order to defrost your outdoor unit. The control board looks to a temperature sensor located in the outdoor unit to determine when to initiate the defrosting cycle.
What are some hints that my Carrier defrost sensor board is failing?
- The system may not operate due in part to the amount of frost on the outdoor unit
- The defrost sequence does not begin even when there is a large quantity of frost on the external unit
- The main board might give out a particular error code produced when the defrost board is bad
