Door Sealing
If the door does not seal correctly, excess frost will collect inside
the refrigerator. Make sure the door seals correctly:

dollar bill (See Art00980).
- Gently pull the paper.
- You should feel a slight drag between the gasket and the
cabinet.
- Do this on all four sides of the door.
- If you do not feel a slight drag on the
paper, the door is not sealing correctly:
- Make sure the screws of the hinges are tight.
- Make sure the door gasket does not touch the door
latch:
- If the door gasket touches the door latch,
loosen the screws of the door latch.
- Raise the door latch just so it does not touch
and tighten the screw s of the door latch.
- Make sure the door latch holds the door closed.
