Operating the Refrigerator Controls (N7V & N8V Models)

Ignition and start up:

Control boards are extremely sensitive. Evidence of tampering or removal from protective case
NOTICE
will VOID any warranty.
Before ignition or start up of the refrigerator :
- Make sure the air flow in the lower intake vent , through the refrigerator coils and condenser, and out the upper
exhaust vent is not blocked or decreased.
- Make sure there are no combustible materials in or around the refrigerator.
- Make sure the DC voltage to the refrigerator is 12.0VDC

Air in the propane gas supply lines

For safety reasons,the refrigerators electronic controls are designed such that while operating in the LP GAS mode, the
NOTICE
trial for ignition (maximum amount of the time the gas valve and igniter can be left on without a flame present) is limitied
to 30 seconds. When starting the refrigerator for the first time, after storage, or after replacing the propane gas tank, the
propane gas supply lines can have air in them.
Due to air in the gas supply lines, the burner may not ignite within the 30 second time limit. In the event this
should happen the gas valve and igniter outputs will be turned off, the LP Gas mode will be "locked out",
and the appropiate fault code will be shown in the display. See fault code section of this manual.
The gas lock out condition can be reset by powering the refrigerator OFF and then back ON, at which time,
a new 30 second trial for ignition will commence. It may be necessary to repeat this procedure 2 to 3 times
before expelling all the air from the LP gas supply line. If after repeated attempts, a flame is not established,
stop and consult your local dealer or Authorized Norcold Service Center.
