International Comfort Products CXA230AKA1 Defrost Sensor Board
The defrost sensor board determines when or if to start an important defrosting cycle which actually helps to keep the outdoor unit free from frost build-up. The control board is influenced by a defrost sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
Some warnings your outdoor defrost sensor board will not live much longer
- The AC may end up not running at all because of the amount of frost on the outdoor unit
- Self defrost sequence never begins even though there is a lot of frost on the unit
- The main circuit board may throw a specific error code when the defrost control board refuses to initialize properly
