Freezer runs but does not get cold enough; temperature stays around -5°C to 0°C even after many hours.

Safety: Unplug the freezer before cleaning or removing panels. Do not bend or puncture refrigerant lines.

Basic checks:

• 1. Verify door seal: Ensure the gasket seals all around and the door is not warped. Replace gasket if torn or hardened.
• 2. Clean condenser: Pull the unit away from the wall. Vacuum dust from the rear grille and condenser coil. Good airflow is critical.
• 3. Check condenser fan (if present): Confirm the fan near the compressor runs when the compressor is on. Replace the condenser fan motor if it does not run.
• 4. Monitor frost pattern: Remove the interior rear panel and briefly observe the evaporator after 10–15 minutes of running. A healthy system shows even frost across most of the coil. Frost only on a small section often indicates low refrigerant or restriction.

When to call a technician: Low refrigerant or a blocked capillary tube requires specialized tools and cannot be repaired safely at home.
