Possible Causes

Open or shorted refrigerator thermistor, Damaged thermistor wiring harness, Corroded thermistor connector at control board

How to Fix / Troubleshooting

Safety: Disconnect power before accessing sensors or control boards.

  • Locate thermistor: In many Maytag refrigerators, the fresh food thermistor is behind a small plastic cover on the rear interior wall of the refrigerator section.
  • Inspect sensor and wiring: Remove the cover and visually inspect the thermistor and its wires for damage, cuts, or corrosion.
  • Check connector at control: At the main control board, verify the thermistor harness is fully seated.

If the E1 code persists, the thermistor should be tested with an ohmmeter (resistance vs. temperature). A faulty reading indicates the sensor must be replaced. If you lack test equipment, replacing the thermistor is usually inexpensive and straightforward.
