Possible Causes

Any of the NTC sensors out of range, Loose sensor connector, Damaged wiring harness, Faulty control board analog input

How to Fix / Troubleshooting

Safety: Disconnect power before testing sensors or removing panels.

Steps:

  • 1. Consult model label: On some IKEA models, E1 is a generic sensor error. Check the user manual or service sheet (often behind the rear panel) for exact mapping.
  • 2. Test all accessible sensors: Freezer compartment NTC, ambient/cabinet NTC, and evaporator NTC. Compare resistance readings to expected values at known temperatures.
  • 3. Inspect harness: Follow sensor wires from the cabinet to the control board, checking for pinched or broken sections.
  • 4. Reseat connectors: Unplug and reconnect all sensor plugs at the board to ensure good contact.
  • 5. Replace faulty sensor or board: If a sensor is out of spec, replace it. If all sensors test correctly, the control board may be misreading and should be replaced.
