Freezer door gasket needed replacement

Decided to replace gasket with door in place on fridge Loosened and removed all gasket retaining screws from behind freezer gasket, including the door shelf. Removed and replaced old gasket with new. Positioning and holding door shelf a bit awkward so have another person hold in place for at least one screw. After this replaceing the remaining screws becomes easy. Do not tighten completely until all screws are in place; then align gasket and alternate tightening. Check for snug fit against fridge and adjust if necessary.
