Refrigerator not cooling at all, interior warm in both fridge and freezer, but lights and display work.

Safety First: Unplug the refrigerator before working near the compressor or electrical components.

Steps:

• Listen for compressor: With the unit plugged in, listen at the back for a humming or clicking sound. Repeated clicks without running suggest a start device issue.
• Inspect start relay/overload: Remove the rear lower panel, locate the compressor, and carefully remove the start relay/overload device from the compressor terminals. Shake it gently; if it rattles, it may be burned out.
• Replace start device: Install a new Midea-compatible compressor start relay/overload assembly and reconnect wiring.
• Test operation: Restore power and allow several minutes to see if the compressor starts and runs steadily.
• Advanced diagnosis: If the compressor still does not start, the compressor itself, inverter board, or main PCB may be defective. These repairs typically require a professional technician.
