F3Dn Service Manual Parts Replacement / Section 2.2
2.2 Freezer Door Gasket Replacement
[Photo 1]
[Part No. 19000685]
1) F3Dn Dispenser should be OFF and the freezer
compartment fully defrosted before proceeding.
2) Open freezer door and inspect the one-piece magnetic
door gasket. If the gasket is torn or crushed so that it
doesn’t completely seal around the door perimeter, it
should be replaced.
3) Remove top door hinge using a 7/16” box wrench or
socket, being careful not to drop the door. Place door on
a non-mar surface with the gasket side facing up.
4) Carefully remove the one-piece gasket from the slotted
plastic extrusion built into the back of the freezer door.
[Note: Plastic extrusion can be easily damaged. Using a
razor knife to separate the old gasket from its retaining
tailpiece may facilitate this procedure. Carefully remove
the separated tailpiece from the slot by pulling toward
each corner using small needle nose pliers. See Photos
2 and 3]
5) Take the new gasket [P/N 19000685] and insert the
tailpiece into the gasket-mounting slot. Align the corners
and start at the top of the door. Continue around the door
perimeter until completely seated. [Tip: Place the door
on a cushioned surface and carefully hammer the new
gasket tailpiece into slot around the door perimeter.]
6) Re-install freezer door on bottom hinge with bushing,
then mount the upper hinge. Be careful to align the door
before tightening the hinge mounting bolts.
7) Test the replacement of the Freezer Door Gasket by:
8) Close the door and visually check the door seal and fit.
9) Turn on main power switch. Allow compressor to draw
down Freezer Compartment temperature. Check with
your hand around the full door perimeter for any leaks of
cold air.
