Common Causes

1
Most likely: Fresh food thermistor

Same as E1 but for fresh food compartment. Resistance test against published curve; thermistor connector may also be corroded.

How to Fix It

  1. Unplug the refrigerator for 5 minutes to reset the control; if E2 returns, continue diagnosing.
  2. Locate the fresh food thermistor (typically behind a cover on the fresh food liner or near the evaporator) and unplug its connector; inspect for corrosion or moisture and reseat it.
  3. Test the thermistor's resistance against the model's service-sheet curve; replace it if open, shorted, or out of range.
  4. If the sensor and wiring test good, the main control board is misreading the circuit and may need replacement.
  5. If diagnosis confirms the fault, replace the fresh food thermistor (typical cost $10-25, about 30 min, easy DIY).
