Display shows temperature, but actual interior temperature is significantly different.

Safety: Unplug the unit before accessing sensors or control board.

Steps:

• Verify with thermometer: Place a reliable thermometer in the center of the cabinet and compare to the display after several hours of stable operation.
• Check sensor placement: Ensure the cabinet thermistor is mounted where it senses average air temperature, not directly in cold air discharge.
• Replace thermistor: If readings are consistently off by a large margin, install a new Frigidaire cabinet temperature sensor.
• Control replacement: If a new sensor does not correct the discrepancy, the control board may be miscalibrated and require replacement.
