Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.

  1. Arrange service if a safe full defrost is impractical. If using the model’s manual-defrost procedure, move food to suitable cold storage first.

    What to note

    Use the result to decide whether the issue is resolved or needs service.

THE DETAILS MATTER

Scope & troubleshooting notes

Interpret this code in context

A defrost warning alone does not prove that the heater failed. Ice blockage and other faults need different diagnoses; preserve the full prefix.

Record what you see

Keep the full model number, exact displayed code, and your observations together for the next conversation.

Use the right support
