Lennox HP13-042 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrost sequence which actually helps to keep the outdoor unit free from frost build-up. The defrost sensor board relies on a defrost sensor which is near the condenser somewhere, in order to verify when to begin.
What happens when my defrost sensor board needs replacing?
- The primary control board could signify an error number when the defrost board fails
- The AC may not operate due in part to the amount of frost on the outdoor unit
- Defrosting never initiates even though there is excessive frost that needs to be removed
