Freezer warm, refrigerator section still somewhat cool, compressor and condenser fan running.

Safety first: Sealed system work involves refrigerant and requires EPA certification. Do not attempt to open the sealed system yourself.

Diagnostic steps (non-invasive):

• 1. Check evaporator frost pattern: Remove the freezer rear panel. A normal system shows a light, even frost across most of the coil. A partial frost pattern (only at the inlet) suggests low charge or restriction.
• 2. Listen to compressor: A running but unusually quiet or very hot compressor with poor cooling often indicates sealed system issues.
• 3. Inspect for oily residue: Look for oil spots on tubing or around joints, which can indicate a refrigerant leak.
• 4. Call a professional: If sealed system failure is suspected, contact a licensed refrigeration technician for leak detection, evacuation, and recharge or component replacement.
