International Comfort Products CXA242AKA1 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrost sequence which aids to keep your outdoor unit from plugging up. The defrost board is relayed information from a sensor located near the condenser to determine when to initiate the defrosting cycle.
Indications the defrost sensor board will not last the year
- Defrosting never starts even though there is excessive frost that makes the unit run like crap
- Your main control board may show an error code produced by a failing defrost board
- The AC may cease to operate for the simple fact of way too much frost build-up
