The defrost sensor board controls if and when to commence the defrost cycle which helps to keep the outdoor unit free from frost build-up. The board is influenced by a specific sensor located near the condenser to make the decision on when to begin.
General indicators that your your defrost board has very little life left
- Defrosting does not begin especially when there is frost on the unit
- The system will stop working due in part to too much frost
- The main board might issue an error code referring to a failing defrost control board
