Freezer not cooling at all; interior remains at room temperature; compressor not running and no humming sound.

Safety: Always unplug the freezer before opening any electrical compartments. Only work on live circuits if you are trained and using proper test equipment.

• Verify power supply: Check that the outlet has power by plugging in another appliance. Reset any tripped breakers or replace blown fuses.
• Inspect power cord: Examine the cord for cuts or burns. Ensure it is firmly plugged in and not loose at the back of the freezer.
• Check internal light and display: If neither works, suspect a main power issue or internal fuse on the PCB.
• Access terminal block: Remove the rear cover to inspect the mains terminal block. Tighten any loose screws and look for signs of overheating.
• Control board and thermostat: If the unit has power but the compressor never starts, the main PCB or thermostat/sensor may not be calling for cooling. This typically requires testing with a multimeter and may be best handled by a technician.
