US Patent 10213050 Grilling appliance with automated platen leveling and gap calibration system

A method of calibrating a grill is provided including performing a first calibration run. A first calibration run includes monitoring a current of a leveling mechanism as the first grilling surface moves into contact with a second opposite grilling surface to determine a first location of the grilling surface. The current of the leveling mechanism is also monitored as the first grilling surface moves out of contact with the second grilling surface to determine a second location of the first grilling surface. A first calibration setting including the first location and the second location is stored in the control.
