Freezer not cooling at all; interior is room temperature; lights may work but no cold air.

Safety first: Unplug the freezer before accessing the compressor or control components. Sealed system work should be left to professionals.

Steps to troubleshoot no cooling:

• 1. Listen for operation: With the unit plugged in, listen for the compressor and fans. If completely silent (except interior light), suspect control or thermostat issues.
• 2. Check temperature setting: Ensure the control is not set to OFF or warmest setting. On mechanical models, verify the thermostat knob is not broken internally.
• 3. Inspect compressor area: Remove the rear lower panel and check if the compressor is warm and vibrating (running) or cold and silent (not running).
• 4. Test start relay/overload: Remove the start device from the compressor and shake it gently; if it rattles or smells burnt, replace it with a Kenmore-compatible start relay/overload.
• 5. Check wiring and connectors: Ensure all wires to the compressor and control board are secure and not burned.
• 6. If compressor runs but no cooling: The sealed system (refrigerant leak, restriction, or failed compressor) may be at fault. This requires a certified technician.

Note: Do not run the freezer for long periods if the compressor is repeatedly clicking on and off; this can cause further damage.
