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 orice, or the ue
area.
Gas ame appearance:
While in GAS operation, regularly examine the gas ame:
- Turn the gas control to the HIGH COOL position.
CAUTION: The burner box cover can be hot. Wear
gloves to avoid burns.
- Look at the gas ame through the observation glass on the
left side of the burner box.
- The ame [175] should be (See Art00955):
- a darker blue color on the inside of the ame and a
lighter blue color on the outside of the ame.
- a constant shape without ickering.
- Contact your dealer or Norcold authorized service center
if the ame is:
- yellow
- ickering or changing shape.
- Make sure the ame does not touch the inside of the
ue tube [76].
- If the ame touches the inside of the ue tube, contact
your dealer or Norcold authorized service center.
