Freezer not cooling at all, interior is at room temperature, compressor not running, display may be on.

Safety: Unplug the freezer before removing the rear panel or touching any electrical parts.

Steps:

• 1. Check power and settings: Confirm the freezer is switched on, not in demo mode, and the temperature is set below 0°C. Verify the outlet has power.
• 2. Listen for compressor: With the unit plugged in and turned on, you should normally hear the compressor hum or feel vibration. If completely silent, proceed.
• 3. Access compressor area: Remove the lower rear cover to expose the compressor, start relay/PTC, and overload protector.
• 4. Inspect start device: Remove the start relay/PTC from the compressor terminals. If it rattles when shaken or shows burn marks, replace it with an "Amica Compressor Start Relay/PTC" matched to your model.
• 5. Overload protector: Test continuity across the overload device. An open circuit indicates it has failed and should be replaced.
• 6. Compressor winding test (advanced): With all power disconnected, measure resistance between compressor terminals. Infinite resistance or a short to ground indicates a failed compressor, requiring professional replacement.
• 7. Control board check: If start components and compressor test good but no voltage reaches the compressor when it should run, the main control board is likely faulty and needs replacement.

When to call a technician: If compressor windings are faulty or you are not comfortable testing high-voltage circuits, contact a refrigeration professional.
