Carrier 38YD Defrost Sensor Board
The defrost sensor control board controls if and when to commence an important defrosting cycle which actually helps to remove frost build-up that may accumulate. It looks to a sensor that can be found near the condenser, in order to agree when to initiate the defrosting cycle.
What to see if the outdoor defrost sensor board is dying?
- The defrost sequence has not run for quite some time even when there is a large quantity of frost on the unit
- The primary control board could throw an alphanumeric error code referring to a failing defrost control board
- Air conditioning may not work due in part to the amount of frost on the outdoor unit
