What Does Error E2 Mean?

The Kenmore air conditioner E2 error indicates a failure in the indoor temperature sensor, leading to erratic temperature readings and potential cooling issues. This can be caused by a malfunctioning thermistor, faulty wiring, or airflow restrictions due to dirty filters or coils. When the E2 code appears, the AC may shut off or limit cooling, and power cycling the unit may not resolve the issue.

Common Symptoms:

  • AC shuts off or limits cooling operation when E2 displays
  • Poor or no cooling
  • Possible inaccurate temperature readings
  • Unit may reset after power cycle but E2 returns

Possible Causes

  • Temperature sensor (thermistor) fault or failure (medium)
  • Sensor wiring or connection issue affecting communication with control board (medium)
  • Airflow restrictions (dirty filters or coils) leading to abnormal sensor readings (medium)

How to Fix Error E2

DIY Fix Basic Reset and Check Filters

  1. Turn off the air conditioner and disconnect power at the mains or unplug it.
  2. Wait at least 5–10 minutes to allow internal electronics to reset.
  3. Clean or replace the air filters to ensure proper airflow.
  4. Restore power and restart the unit to check if E2 clears.

Technician Only Inspect and Repair Sensor & Wiring

  1. Disconnect power and remove access panels to reach the indoor unit’s sensors.
  2. Visually inspect sensor wiring and connectors for damage, corrosion, or loose connections.
  3. Test thermistors/temperature sensors with a multimeter to confirm correct resistance values.
  4. Replace any faulty sensors and ensure connectors are secure.
  5. Reassemble and test the unit for normal operation.

Parts needed: temperature sensors (thermistors), wiring harness connectors

🛑 When to Call a Pro:
  • The E2 code persists after basic reset and filter cleaning
  • Visible electrical damage or corrosion on wiring or control board
  • Uncertainty in safely accessing internal components
