Display shows E9 and the refrigerator may run continuously or not cool properly; compressor may be hot.

Safety first: Unplug the refrigerator before accessing the rear compartment.

Steps:

• Access condenser area: Remove the lower rear cover to expose the condenser coils, condenser fan motor, and associated wiring.
• Clean condenser: Use a soft brush and vacuum to remove dust and lint from the condenser coils. Blocked coils can cause overheating and trigger E9.
• Check condenser fan: Spin the fan blades by hand; they should move freely. With power restored briefly, verify that the fan runs when the compressor is on. If it does not, unplug again and plan to replace the fan motor.
• Locate condenser sensor: The condenser NTC sensor is often clipped to the condenser tubing or near the compressor. Inspect for damage or dislodging.
• Test sensor: Disconnect the sensor and measure resistance. Open or short readings indicate failure.
• Replace faulty parts: Install a new Etna condenser NTC sensor if defective. Replace the Etna condenser fan motor if it does not run or is noisy.
• Reassemble and test: Refit the rear cover, restore power, and monitor operation. The E9 code should clear once normal temperatures are detected.
