Beko Refrigerator: temperature sensor issue

Professional Repair Guide

What is this symptom?

Experiencing temperature fluctuations in your Beko refrigerator? Inaccurate readings, constant compressor operation, and error codes like E1/E2/E3 may indicate a temperature sensor issue. This can lead to food spoilage or freezing, making it crucial to diagnose and fix the problem promptly.

Urgency: Medium

Important Tips for Beko Models

  • Beko refrigerators use error codes E0–E3 to indicate specific sensor faults, including fridge and freezer sensor errors (e.g., E1/E2/E3 correlate to fridge sensor issues).

Possible Causes

Faulty temperature sensor (thermistor)

How to Identify: Error codes like E1/E2/E3 on display; temperature display doesn’t match an independent thermometer; inconsistent cooling cycles; fridge/freezer too warm or too cold despite settings.

Part: Temperature sensor / thermistor

Loose, corroded or damaged wiring/connectors to sensor

How to Identify: Visible corrosion or loose plugs at sensor or main control board; intermittent error codes; cleaning and reseating may improve readings.

Part: Sensor wiring harness and connectors

Ice or frost buildup around sensor

How to Identify: Ice encasing sensor area; sensor readings fluctuate; defrosting improves performance temporarily.

Part: Sensor location/compartment

Faulty control board misinterpreting sensor input

How to Identify: Sensor tests good but errors persist; other component behaviors abnormal; replacement of sensor doesn’t fix issue.

Part: Main control board

DIY Solutions

Check and reseat sensor connections

Moderate 15-30 minutes
Tools Needed: screwdriver, flashlight
  1. Unplug the refrigerator.
  2. Locate the fridge temperature sensor (behind interior back panel or near vent).
  3. Inspect wiring connectors for corrosion or looseness.
  4. Disconnect and reconnect the sensor plug to ensure secure fit.
  5. Restore power and monitor temperature behavior.
⚠️ Safety First: Always disconnect power before accessing internal components.

Defrost sensor area if ice buildup is present

Easy 2-6 hours (passive defrost)
Tools Needed: towels, container for water
  1. Unplug fridge and open doors to allow ice to melt.
  2. Place towels to catch water.
  3. Leave doors open until ice around sensor melts.
  4. Clean area gently and restart fridge to re-evaluate temperature behavior.
⚠️ Safety First: Do not use sharp tools or heat guns to speed defrosting.

Test temperature sensor with a multimeter

Advanced 30-60 minutes
Tools Needed: digital multimeter, screwdriver
  1. Unplug the refrigerator.
  2. Locate and access the sensor.
  3. Disconnect sensor from wiring.
  4. Measure resistance at room temperature and compare against expected values (model-specific).
  5. Replace sensor if resistance out of range.
  6. Reinstall and power on to verify improvement.
⚠️ Safety First: Only attempt if comfortable with basic electrical testing.

Common Issues Reported by Users

  • Faulty temperature sensor (thermistor)
  • Wiring issues or loose connections to the temperature sensor
  • Faulty control board affecting temperature readings

User Suggested Solutions

  1. Inspect and replace the faulty temperature sensor. Disconnect power, locate the sensor (usually in the fridge or freezer compartment), remove the old sensor, and install the new one. Reconnect power and test the temperature.

  2. Check wiring and connections to the temperature sensor. Disconnect power, inspect the wiring for damage or loose connections, repair any issues, and reconnect power to test.

  3. Test and possibly replace the control board. Disconnect power, access the control board, check for visible damage or burnt components, and replace if necessary. Reconnect power and test.
