Freezer not running at all; no lights, no display, completely dead.

Safety: Always unplug the freezer before opening any access panels. Use caution around mains wiring.

Steps to restore power:

• Check outlet and breaker: Test the outlet with another device. Reset any tripped breakers or replace blown fuses in the home panel.
• Inspect power cord: Look for cuts, burns, or crushed sections. If damaged, replace the entire cord with a compatible Costway freezer power cord.
• Check internal fuse (if equipped): Remove the rear lower panel to access the main control board. Look for a small glass or ceramic fuse on the board or in-line with the AC input. Test for continuity and replace with the same rating if blown.
• Verify connections: Ensure the AC input connector is firmly seated on the control board and no wires are loose.
• Test operation: Reassemble, plug in, and see if lights or display come on.

Call a technician if: The fuse blows again immediately or there are signs of burnt components on the board, indicating a deeper electrical fault.
