Why does the grill pan lid rattle or lift while cooking?

Direct answer

If the lid rattles or lifts during cooking, check that it is seated correctly and that steam or food moisture is not building up faster than expected. A loose fit can also happen if the unit is not level.

Diagnostic steps

1. Turn off the appliance and let it cool before checking the lid position.
2. Make sure the lid is aligned and closed according to the product design.
3. Place the grill pan on a flat, stable surface.
4. Reduce the amount of food or liquid if the lid is being pushed up by steam.

Expected result

The lid should stay seated without obvious movement during normal cooking.

When to stop

Stop if the lid is cracked, warped, or cannot be seated securely.

When to contact support

Contact support if the lid still lifts or rattles after correct placement and reduced steam load.
