Refrigerator not cooling properly; compressor runs but condenser coils are only slightly warm.

Safety first: Do not attempt to open the sealed refrigeration system yourself. Refrigerant handling requires certification.

• Step 1 – Basic checks: Ensure condenser fan is running and coils are clean. Confirm doors are sealing properly.
• Step 2 – Feel system temperatures: With the unit running, carefully feel the condenser coils; they should be noticeably hot. If only mildly warm and cooling is poor, a sealed-system issue is likely.
• Step 3 – Look for oil stains: Inspect around joints and the compressor for oily residue, which can indicate a refrigerant leak.
• Step 4 – Call a professional: Sealed-system diagnosis, leak detection, and recharging must be done by an authorised refrigeration technician. In many cases, replacing the refrigerator may be more economical, especially if the leak is in the cabinet.
