Carrier 50XT-A30 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin an important defrosting cycle if necessary, to remove frost build-up that may accumulate. The control board depends on a temperature sensor located near the condenser to ascertain when to begin.
Key clues of a laboring outdoor defrost sensor board
- Defrosting has not run for quite some time even though there is quite a bit frost on the unit
- Your HVAC system will cease to operate for the simple fact of the frost issue
- The main circuit board may issue an error of some type if the defrost board fails
