Freezer not cooling at all; interior is warm and food is thawing, but lights may still work.

Safety First: Always unplug the freezer before removing access panels or touching electrical parts. If you smell burning or see smoke, do not attempt repair—call a professional.

• Step 1 – Verify power supply: Check that the outlet has power by plugging in another device. Reset any tripped breakers or GFCI outlets.
• Step 2 – Listen for compressor: With the unit plugged in and turned on, listen at the back for the compressor humming or clicking. Repeated clicking without running often indicates a bad start relay.
• Step 3 – Check temperature control: Ensure the control is not set to OFF. On mechanical models, rotate the thermostat from OFF to coldest and listen for a click.
• Step 4 – Inspect start relay: Unplug the freezer, remove the rear access panel, and pull off the compressor start relay/PTC. If it rattles when shaken or shows burn marks, replace it.
• Step 5 – Further diagnosis: If the compressor still does not run, the issue may be the cold control thermostat or electronic control board, which typically requires advanced testing or a technician.
