Possible Causes

Defrost system failure causing heavy frost on freezer evaporator, Weak compressor affecting low-temperature performance, Door gasket leak on freezer door, Blocked freezer air vents

How to Fix / Troubleshooting

Safety: Unplug the appliance before removing panels or working near the evaporator.

  • Check door seal: Inspect the freezer gasket for gaps or tears. Close the door on a sheet of paper; if it pulls out easily, adjust hinges or replace the gasket.
  • Inspect frost pattern: Remove the freezer rear interior panel. If the evaporator is heavily iced over, the defrost system may have failed.
  • Manual defrost: Unplug the fridge and fully defrost the freezer, leaving the door open. Do not use sharp tools to remove ice.
  • Check defrost components: After defrosting, test the defrost heater, thermal fuse/thermostat, and evaporator sensor as described in defrost-related entries. Replace faulty parts with Grundig-compatible components.
  • Reassemble and monitor: Restore power and monitor freezer temperature over 24–48 hours.
