Carrier 50JS048300 Defrost Sensor Board
The defrost sensor board controls if and when to commence the defrosting phase if necessary, to keep the outdoor unit free from frost build-up. The control board relies on a temperature sensor located near the condenser to decide when to initiate the defrosting cycle.
How can I tell if my defrost sensor board is crapping out?
- Your system could not work because of frost blocking the fins on the outside unit
- The defrost feature does not run even though there is excessive frost that makes the unit run like crap
- The main board may signify an alphanumeric error code when encountering a problem
