What Does Error E02 Mean?

The Hitachi refrigerator E02 error indicates a malfunction in the temperature sensor, which can lead to fluctuating temperatures and inadequate cooling performance. This issue typically arises from a failure of the temperature sensor (thermistor) or a faulty temperature monitoring circuit. Immediate attention is required to restore proper functionality.

Common Symptoms:

  • Error code E02 displayed on panel
  • Refrigerator/freezer temperature irregular or not cooling properly
  • Possible lack of normal cooling operation

Possible Causes

  • Temperature sensor (thermistor) failure or malfunction (medium)
  • Faulty temperature monitoring circuit or wiring to sensor (low)

How to Fix Error E02

DIY Fix Basic checks before service

  1. Check that refrigerator doors are fully closed and seals are intact
  2. Ensure power has been stable and unplug the refrigerator for 5 minutes to reset control circuitry
  3. Observe if the error returns after normal power is restored

Technician Only Diagnose/replace temperature sensor

  1. Disconnect refrigerator from power
  2. Access temperature sensor/thermistor in refrigerator/freezer compartment
  3. Test sensor resistance with multimeter to verify if out of specification
  4. Inspect wiring harness and connectors for damage or poor connection
  5. Replace faulty sensor or repair wiring as needed
  6. Reassemble and test cooling performance and error absence

Parts needed: Temperature sensor (thermistor), Wire harness/connector if damaged

🛑 When to Call a Pro:
  • If error persists after basic reset and checks
  • If multimeter tests show sensor or wiring faults beyond simple fix
  • If unfamiliar with safe electrical/device servicing
