Carrier LJE Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrosting phase which assists to rid your unit of frost that can build up. The defrost board is influenced by a specific sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
What warnings are present when my outdoor defrost sensor board is failing?
- The defrost sequence never kicks in despite that there is a large amount frost on the external unit
- AC and heating system could not run because of the safety issue that the frost poses
- The main board could throw an error number produced by a bad defrost control board
