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

Safety: Sealed system work involves refrigerant and must be performed by a licensed technician. Do not attempt to cut or open refrigerant lines yourself.

Diagnostic steps (visual only):

• 1. Check door seal and loading: Ensure the door gasket seals well and the freezer is not overloaded with warm food, which can mimic low capacity.
• 2. Listen and feel: Confirm the compressor runs steadily and the condenser gets warm.
• 3. Inspect frost pattern: Remove the inner rear panel and observe the evaporator after 20–30 minutes of running. A healthy system shows even frost across most of the coil. Frost only near the inlet or no frost suggests low refrigerant or restriction.
• 4. Call a professional: If the frost pattern is abnormal and basic checks are fine, contact an authorized Toshiba service center for leak detection, evacuation, and recharge or component replacement.
