How to Fix Error E12

DIY Fix Check control panel and power reset

  1. Unplug the refrigerator or switch off its power at the circuit breaker.
  2. Wait 5–10 minutes to allow any control electronics to discharge.
  3. Restore power and observe whether the E12 code disappears.
  4. Ensure the display panel is clean and no obvious electrical issues (loose plug, flickering display) are present.

Technician Only Professional diagnosis of sensors and control electronics

  1. Access the refrigerator control board and internal sensors.
  2. Use manufacturer-specific diagnostic tools to read detailed error logs tied to the specific model’s E‑Nr.
  3. Test temperature sensors, humidity sensors, and control board outputs for correct readings in context of the E12 code.
  4. Replace any failed sensor or control module with genuine Siemens parts according to service documentation.

Parts needed: Temperature sensors, Humidity sensors (if present), Control board / main PCB

🛑 When to Call a Pro:
  • If the error persists after power cycling the unit.
  • If there are signs of abnormal temperature in the refrigerator or freezer compartments.
  • If there is no official error code definition available for your model and diagnosis requires specialized tools.
