Flash Pattern "5" means the gas valve is “mechanically” stuck
open and subsequently the Power Board has sensed a

present when there should not be. This fault can be displayed
in ANY MODE.
• Replace the gas valve

Power ON indicator light flashes ON eight times, OFF for 5-seconds, repeats
NOR000122-8A
Flash Pattern "8" means the refrigerator attempted to ignite or
re-ignite the burner when the DC input voltage was less than
10.0 VDC. The gas valve/igniter outputs are inhibited when
there is a call for cooling and the DC voltage is less than 10.0
VDC. Should there be a call for cooling while the DC input
voltage is greater than 10.0 VDC and the DC input voltage
then falls below 10.0 VDC, the gas valve will remain energized
and no fault will be displayed. This fault can only be displayed
in the Auto and Manual LP modes.
Verify:
• That the battery charging equipment of the vehicle is
operational
• That the AC/DC converter is operational (if applicable)
• If voltage is
>
10.0 VDC replace power board

NOR000122-9A
Flash Pattern "9" means the DC voltage to the refrigerator is
less than 8.5 volts DC. All outputs are inhibited. This fault will
automatically reset and outputs will be allowed to operate once
the DC input voltage rises above 9.0 VDC (above 10.5 for
3-way models). This fault can be displayed in ANY MODE.
Verify:
• That the battery charging equipment of the vehicle is
operational
• That the AC/DC converter is operational (if applicable)
• Contact Customer Service for further instructions.
