What Are the Frigidaire Fault Codes?
Common fault codes for Frigidaire refrigerators and freezers include SY EF, which indicates evaporator fan circuit failure and OP, which indicates freezer sensor open in freezer display or fresh food sensor open in refrigerator display. A full list of error codes can be found on the SearsPartsDirect website.
To fix an evaporator fan circuit failure, first check the wiring between the control board and the evaporator. Ensure that the red and brown wires are supplying sufficient energy to the fan by measuring their voltage. If the voltage is correct, consider replacing the evaporator fan. If the fault code persists, replace the control board too.
The freezer sensor open or fresh food sensor open error mostly occurs when there is a wiring problem between the thermistor and control board. However, if the wiring is correct, consider replacing the thermistor. Another fault code caused by a malfunctioning thermistor is SH, which indicates freezer or fresh food sensor shorted. When this error occurs, first check the wiring, and if the wiring is correct, replace the temperature sensor.
Additional error codes for Frigidaire refrigerators and freezers include SY CE, which indicates communications error at power-up, and SY CF, which indicates communications failure at power-up. These two fault codes occur when there is a wiring problem between the user interface and the control board.
