Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the freezer before cleaning or accessing the rear compartment. Do not attempt to open the sealed refrigeration system yourself.
Step-by-step checks:
- 1. Check condenser cleanliness: Pull the freezer away from the wall. Remove the rear lower panel and inspect the condenser coil. If it is clogged with dust, clean it gently with a soft brush and vacuum.
- 2. Verify ventilation: Ensure there is adequate clearance around the freezer as specified in the user manual. Poor airflow can cause high temperatures and trigger E9.
- 3. Observe frost pattern: After running for 20–30 minutes, remove the interior rear panel and inspect the evaporator. A normal system will have an even frost pattern across most of the coil. Frost only at the inlet or no frost at all suggests a sealed system issue.
- 4. Listen to compressor: A noisy or very hot compressor that runs constantly with poor cooling indicates internal wear or low refrigerant.
- 5. Temporary measures: Move food to another freezer if possible to prevent spoilage while arranging service.
When to call a technician: Any suspected refrigerant leak, capillary blockage, or compressor problem must be handled by a certified refrigeration technician with proper tools and refrigerant handling certification.
