International Comfort Products CAC424AKA1 Defrost Sensor Board
The defrost sensor control board determines when or if to start an important defrosting cycle which may be necessary to get rid of the frost that collects on the outdoor unit. It relies on a sensor that can be found near the condenser, in order to ascertain when the defrost cycle should begin.
How can I tell if my defrost board has to be replaced?
- Defrosting will not initiate despite the fact that there is a lot of frost that makes the unit run like crap
- The control board could signify an error code produced by a bad defrost control board
- Your HVAC system will end up not running due to the fact of the safety issue that the frost poses
