Freezer not cooling at all – interior remains at room temperature, compressor not running.

Safety warning: Unplug the freezer before accessing the compressor or control board. Capacitors can hold charge; avoid touching board components unnecessarily.

Diagnostic and repair steps:

• 1. Verify power and controls: Confirm the outlet has power and the freezer is switched on. Check that the temperature control is not set to OFF or the warmest setting.
• 2. Listen for activity: Plug in the freezer and listen for clicks or humming from the compressor area. If completely silent, suspect control or start components.
• 3. Inspect compressor start device: Remove the rear lower panel and examine the compressor start relay and overload. Look for burn marks or melted plastic. Replace if damaged.
• 4. Test compressor windings: With the unit unplugged and start device removed, measure resistance between the three compressor pins. You should see finite resistances between each pair and no continuity to ground. An open winding or short to ground indicates a failed compressor.
• 5. Check wiring and control board: Trace the wiring from the main control PCB to the compressor start device. Repair any breaks. If wiring and start device are good but the compressor never receives power, the main control PCB may be faulty.
• 6. Decide on compressor replacement: If the compressor is electrically or mechanically failed, replacement requires refrigerant recovery and recharging, which must be done by a certified refrigeration technician.

Recommendation: For compressor or sealed-system work, contact a professional; DIY attempts can be unsafe and may violate regulations.
