Air in the propane gas supply lines
For safety reasons,the refrigerators electronic controls are designed such that while operating in the LP
NOTICE
GAS mode, the 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 sveral 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.
