Freezer emits a strong chemical or refrigerant-like odor.

Safety first: If you suspect a refrigerant leak (sharp chemical smell, hissing), ventilate the area and avoid open flames or sparks.

• Inspect visually: Look behind and under the freezer for oily residue on tubing or around the compressor, which can indicate a leak.
• Check for overheating: Smell near the control board and wiring for burnt plastic or insulation. If found, unplug immediately.
• Do not attempt sealed system repair: Refrigerant handling requires certification and specialized tools.

Contact a qualified refrigeration technician to locate and repair any leaks or electrical overheating issues. Do not continue to operate the freezer if a strong chemical or burning smell persists.
