Freezer not cooling at all, interior is at room temperature, but lights and display work.

Safety first: Unplug the freezer before removing rear panels. Do not attempt to open the sealed refrigerant system unless you are a certified technician.

Checks you can do:

• Listen for compressor: After plugging in, listen at the back. If the compressor is silent and not vibrating, it may not be starting.
• Check compressor start components: Remove the rear lower panel and inspect the start relay/PTC and overload protector on the compressor. Replace these inexpensive parts first if they show signs of damage.
• Condenser fan: On models with a condenser fan, ensure it runs when the compressor should be on.
• Frost pattern: If accessible, remove the interior rear panel and check the evaporator after 15–20 minutes of running. No frost at all suggests a sealed-system issue.
• Professional repair: If the compressor runs but there is no cooling or only a small patch of frost, the problem is likely a refrigerant leak or internal blockage. Contact a refrigeration technician for leak detection, evacuation, and recharging or compressor replacement.
