Possible Causes

Out-of-spec cabinet thermistor, Poor sensor placement, Control board calibration drift, Air stratification inside cabinet

How to Fix / Troubleshooting

Safety: Unplug the unit before accessing the sensor.

  • Verify with a thermometer: Place an accurate thermometer in the center of the cabinet away from walls and compare to the display after several hours of stable operation.
  • Check sensor placement: Ensure the cabinet thermistor is properly mounted and not touching the evaporator or walls directly.
  • Test thermistor: Measure resistance and compare to Amana's temperature-resistance chart. Replace if out of tolerance.
  • Allow for stratification: Recognize that some temperature variation between top and bottom shelves is normal. Use the middle shelves for the most critical bottles.
  • Control board replacement: If the sensor is accurate but the display remains significantly off, the main control board may be miscalibrated and require replacement.
