Refrigerator Storage
Before the refrigerator is stored for an extended (seasonal)
period of time:
- Defrost and clean the interior of the refrigerator.
- Close the doors with the storage latch.
If the refrigerator is stored for an extended period of time, before
start up:
- Make sure there are no obstructions in the vents, the
ventilation air pathway, the burner, the orifice, or the flue
area.
If the door does not seal correctly, excess frost will collect inside
the refrigerator. Make sure the door seals correctly:
- Close the door on a piece of paper that is about the size
and thickness of a dollar bill (See Art00980).
- Gently pull the paper.
- You should feel a slight drag between the door gasket
and the cabinet.
- Do this on all four sides of the door.
- If you do not feel drag on the paper, the door gasket is not
sealing correctly.
- Contact your dealer or Norcold authorized service center.
Door Sealing
- Make sure the thermocouple tip is clean and secure.
- Make sure the area at the rear of the refrigerator is free from
any combustible materials, especially gasoline and other
flammable vapors and liquids.
