What U (pan symbol) Means
A U-shaped symbol flashing on a Dacor Discovery or Heritage induction cooking zone is not an error. Dacor’s manual explains it represents the cross-section of a pan and appears when a zone is set but no suitable pan is detected.
Common Causes of U (pan symbol)
- Zone switched on with no pan on it
- Non-magnetic cookware such as aluminum or copper
- Pan too small for the zone or off center
🔧 One Safe Check You Can Try
Center a magnetic pan on the zone, use a smaller zone for a small pan, and check that the pan bottom is flat. A magnet that sticks firmly to the base confirms induction-ready cookware.
⚠ Why You Shouldn't Go Further Than That
- If a correct, centered pan still is not detected, the zone’s coil or board needs testing.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
