What Does Error E2 Mean?

The Kenmore dehumidifier E2 error code indicates a malfunction of the evaporator coil thermistor, resulting in inaccurate temperature readings. This can lead to erratic display readings, cycling behavior, or inadequate dehumidification. A thorough inspection of the thermistor and wiring is recommended to identify the issue.

Common Symptoms:

  • E2 displayed on control panel while unit attempts to operate
  • Possible unit cycling or shut‑down behavior when sensor readings are out of expected range
  • Reduced or abnormal dehumidification performance associated with sensor fault

Possible Causes

  • Evaporator coil thermistor (temperature sensor) malfunction (high)
  • Loose or insecure wire harness connection to evaporator coil thermistor (medium)
  • Faulty electronic control board (secondary cause if sensor and wiring are confirmed good) (medium)

How to Fix Error E2

DIY Fix Basic inspection and reset

  1. Unplug the dehumidifier from power and wait at least 5 minutes.
  2. Check that the unit is placed in a stable, dry place with adequate airflow around it.
  3. Plug the unit back in and power on to see if the E2 code clears.

Technician Only Thermistor sensor wiring and replacement

  1. Disconnect power to the unit.
  2. Access the evaporator coil area and locate the thermistor wiring harness.
  3. Verify the harness connector is secure and free of corrosion or damage.
  4. If wiring is good, measure thermistor resistance and replace the sensor if readings are out of spec.
  5. Reassemble and test unit operation, verifying that the E2 code is resolved.

Parts needed: Evaporator coil thermistor sensor, Wire harness/connectors

Technician Only Control board diagnosis and replacement

  1. Confirm sensor and wiring are functioning correctly before proceeding.
  2. Diagnose the electronic control board for faults related to sensor input circuitry.
  3. Replace the control board if confirmed faulty.
  4. Test unit for proper operation post‑repair.

Parts needed: Electronic control board

🛑 When to Call a Pro:
  • If after basic user inspection and reset the E2 code persists
  • If internal components such as sensors or control boards need testing/replacement and you are not experienced with electrical appliance repair
  • If the unit shows additional error codes or unusual behavior beyond E2
