0 of 2 checked

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

  1. Wait for the normal temperature indication or completion tone described by the manual.

    What to note

    The display progresses as the oven warms.

  2. If preheating never completes or food is not heating normally, investigate that separate symptom.

    What to note

    A normal status is not mistaken for a fault.

THE DETAILS MATTER
