Arrived at location on 2/14/22 - griddle leaking grease down left side by grease tray. Checked over, found small amount of build up above tray that could cause grease to migrate away from tray. Cleaned up inside unit further around opening where grease goes down into tray. Turned on and allow to heat up. Unit should be okay for use. Informed Gerald to let us know if they continue having issues.
