International Comfort Products CXA248AKA1 Defrost Sensor Board
The defrost sensor board commences an important defrosting cycle which may be needed in order to keep your outdoor unit from plugging up. The defrost sensor board depends on a defrost sensor located near the condenser to determine when to begin.
What are some indications that my defrost sensor board is almost going bad?
- Your HVAC system will not operate at all because of the safety issue that the frost poses
- The defrost sequence never begins despite the fact that there is quite a bit frost built up
- The main control board could signify an alphanumeric error code referring to a failing defrost control board
