Carrier 48XL-A30 Defrost Sensor Board
The defrost sensor control board will begin an important defrosting cycle which aids to continue normal heating and cooling operations. The control board is relayed information from a specific sensor located near the condenser to agree when to initiate the defrosting cycle.
Major signs your Carrier defrost sensor board is on its last leg
- The main control board might issue an error of some type if the defrost control board fails
- Defrosting never begins especially when there is frost on the external unit
- Air conditioning may not operate because of too much frost
