Possible Causes

Blown internal fuse on main PCB, Faulty mains cable or plug, Failed PCB power supply section, Tripped household circuit breaker

How to Fix / Troubleshooting

Safety: Always unplug the freezer before inspecting the plug or PCB. If a breaker trips repeatedly, do not reset continuously.

Steps to diagnose no‑power condition:

  • 1. Check outlet and breaker: Test the socket with another appliance. Reset any tripped breaker once; if it trips again when the freezer is plugged in, stop and call an electrician or technician.
  • 2. Inspect mains cable and plug: Look for cuts, burns, or loose pins. Replace the plug or cable if damaged.
  • 3. Access main PCB: Remove the PCB cover and look for an onboard fuse. Test continuity and replace with the exact same rating if blown.
  • 4. Inspect PCB: Look for burnt components in the power supply area. If present, replace the entire PCB.

Warning: Do not bypass fuses or use oversized replacements; this is a fire hazard.
