8. Adjust the door position by moving the door frame to
seal any gap between the gasket and the oven front
near the hinges. Then tighten the hinge screws.
Be careful not to compress the gasket too much, or it
will cause the door to bind near the hinges.

10. To check the gasket compression, close the door
with a dollar bill between the gasket and the front of the
oven. You should feel resistance when you try to pull
the dollar bill out with the door closed. Do this check in
several places and re-adjust the door if necessary.
