International Comfort Products CAC230AKA1 Defrost Sensor Board
The defrost sensor board commences an important defrosting cycle if necessary, to keep the outdoor unit free from frost build-up. The defrost board is influenced by a specific sensor which is near the condenser somewhere, in order to agree when the defrost cycle should begin.
Signs the defrost sensor board is going out
- The primary control board may signify an error code when the defrost control board refuses to initialize properly
- Most systems will stop operating due in part to the frost blocking the flow of air
- Unit defrost session refuses to initiate despite that there is a large amount frost on the unit
