Carrier 58CVX15510022 Defrost Sensor Board
The defrost sensor board commences the defrosting phase in order to keep the outdoor unit free from frost build-up. The control board relies on a defrost sensor that can be found near the condenser, in order to determine when the defrost cycle should begin.
How can I tell if my defrost board is not working properly?
- The defrost sequence does not run even though there is a large amount of frost on the unit
- The AC may stop running due in part to the fact that there is too much frost
- The primary control board could display an alphanumeric error code when the defrost control board refuses to initialize properly
