Carrier 38EYA030 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrost cycle which helps to keep your outdoor unit from plugging up. The defrost board is relayed information from a defrost sensor located in the outdoor unit to verify when the defrost cycle should begin.
Easy warnings of a weakening defrost board
- The main board may show a specific error code produced by a bad defrost control board
- Most systems will not run at all because of frost blocking the airflow outside
- Defrosting has not run for a while especially when there is a rather large amount of frost on the outdoor unit
