Frigidaire FRS093LC1 Defrost Sensor Board
The defrost sensor board commences the defrost sequence which actually helps to keep your outdoor unit from plugging up. It is relayed information from a temperature sensor located somewhere by the condenser to ascertain when to begin.
Indications the AC defrost sensor board will not live much longer
- Your main control board may issue an error code referring to the failed defrost sequence
- The defrost feature never begins especially when there is a rather large amount of frost in the way
- The AC may cease to operate because of frost blocking the fins on the outside unit
