How to Fix Electrolux Refrigerator Error F4

Error Code: F4 Difficulty: Hard

Problem: Temperature error, indicating a defective temperature sensor.

How to Fix F4 Error (Step-by-Step)

1. Disconnect the refrigerator from power to prevent electrical shock and confirm the error stays cleared during a full test cycle.
2. This error points to a temperature sensor. There are two common sensors: one in the fresh food section (Part #240597203) and one in the freezer (Part #297018400).
3. First, check the fresh food sensor, which is usually visible near a light or air vent. Inspect its wiring for loose connections or damage.
4. To check the freezer sensor, you will need to remove the contents, shelves, and the interior back panel of the freezer.
5. Once accessed, visually inspect the freezer sensor and its wiring for any breaks, corrosion, or loose plugs.
6. Because diagnosing which sensor has failed requires a multimeter and technical knowledge, this is considered a professional repair.
7. If you’ve checked the connections and the error remains, schedule a service call with a certified service for proper diagnosis and part replacement.
8. Turn the appliance off, wait about 2 minutes, then turn it back on.

Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
