the refrigerator. Make sure the door seals correctly:

and thickness of a dollar bill (See Art00980).

the cabinet.

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:

loosen the screws of the door latch.
- Raise the door latch just so it does not touch
and tighten the screws of the door latch.
