Display shows E9 and the unit may not cool or may shut down unexpectedly.

Safety first: Unplug the appliance before cleaning or working near the compressor and condenser. Allow hot components to cool.

Steps to resolve E9 overheat issues:

• 1. Check installation: Ensure the wine cooler has the recommended clearance around sides, back, and top as per Brandt manual. Move it away from heat sources.
• 2. Clean condenser: Remove the rear lower panel to access the condenser coil. Use a soft brush and vacuum to remove dust and lint. Do not bend the fins.
• 3. Verify condenser fan operation: With the unit powered (briefly), observe whether the condenser fan runs when the compressor is on. If not, unplug and test the fan motor for continuity and free rotation.
• 4. Replace condenser fan if faulty: Install a new Brandt-compatible condenser fan motor if the old one is seized or electrically open. Ensure correct airflow direction.
• 5. Check ambient temperature: Very high room temperatures can trigger overheat protection. If possible, relocate the unit to a cooler environment.
• 6. Control board and sensor check: If airflow is good and fans are working, but E9 persists, the overheat sensing circuit on the main PCB may be faulty. This typically requires board replacement by a technician.
• 7. Monitor operation: After cleaning and repairs, run the cooler for several hours and confirm that temperatures stabilize and E9 does not return.
