Refrigerator runs constantly, poor cooling, E10 error

Safety first: Unplug the refrigerator before removing rear panels. Do not attempt to open the sealed refrigeration system.

Basic checks:

• Ventilation: Ensure there is adequate clearance around the fridge (typically at least 2–3 inches at the back and top). Clean dust from the rear grille and surrounding area.
• Condenser coils: Clean coils thoroughly with a brush and vacuum to improve heat dissipation.
• Listen to compressor: After restoring power, listen at the back. A clicking sound every few minutes or loud humming followed by shutdown can indicate compressor or inverter issues.
• Check inverter connections: With power disconnected, inspect the small inverter board mounted near the compressor. Ensure all plugs are fully seated and there is no visible damage or burn marks.

Important: Compressor and inverter diagnostics beyond visual inspection require specialized tools and training. If E10 persists after cleaning and verifying ventilation, contact a qualified technician.
