The defrost sensor control board instructs the outdoor unit to begin the defrost sequence in order to keep your outdoor unit from plugging up. The control board relies on a specific sensor that can be found near the condenser, in order to decide when the defrost cycle should begin.
General indicators that your your Carrier defrost sensor board has little life left
- Defrosting never starts even though there is excessive frost on the unit
- The main circuit board could signify an error number when the defrost board fails
- Most systems will stop operating at all because of frost blocking the fins on the outside unit
