What Does Error OP Mean?

The Electrolux refrigerator OP error indicates an open circuit in the temperature sensor, which can cause inaccurate temperature readings. Symptoms include the OP code displayed in the freezer or refrigerator, and temperature readings may freeze at a default value. This issue is often due to a disconnected or faulty temperature sensor (thermistor), leading to compressor overload protection activation and unusual humming sounds.

Common Symptoms:

  • OP displayed in freezer temperature display
  • OP displayed in refrigerator temperature display
  • Temperature readings may be missing or frozen at a default value

Possible Causes

  • Open or disconnected temperature sensor (thermistor) circuit (medium)

How to Fix Error OP

DIY Fix Basic checks for temperature sensor issue

  1. Unplug the refrigerator from the power outlet.
  2. Locate the temperature sensors (thermistors) in the freezer and refrigerator compartments.
  3. Visually inspect the connectors and wiring harness for loose or disconnected wires.
  4. Reconnect any loose connectors securely.
  5. Plug the refrigerator back in and check if the OP code clears.

Technician Only Diagnose and replace temperature sensor or repair wiring

  1. Disconnect power and gain access to internal control board and thermistor wiring.
  2. Use a multimeter to measure resistance of temperature sensors; infinite resistance indicates open circuit.
  3. Inspect wiring harness for breaks, corrosion, or damage.
  4. Repair wiring or replace the thermistor(s) as needed.
  5. Test the refrigerator after repairs to confirm the error code no longer appears.

Parts needed: Temperature sensor (thermistor), Wire harness/connectors

🛑 When to Call a Pro:
  • If you are not comfortable accessing internal components
  • If the error persists after basic wiring checks
  • If sensors and wiring appear intact but the error remains
