Carrier 24ABR330A0031010 Defrost Sensor Board
The defrost control board will begin an important defrosting cycle which may be needed in order to rid your unit of frost that can build up. The defrost sensor board is relayed information from a sensor located in the outdoor unit to verify when to begin.
Simple signals your defrost board is on its last leg
- Air conditioning may stop functioning at all because of the fact that there is too much frost
- The main circuit board might issue a specific error code if the defrost board goes out
- The defrost sequence never starts especially when there is frost that has built up
