code
NOR000124A-noac
Meaning:
The Power Board sensed the refrigerators AC input voltage to
be less than 85 volts. This fault, by itself, can only be displayed
while operating in the Manual AC Mode. This fault can be
displayed in conjunction with other faults while operating in the
Auto Mode. For example; no AC followed by no FL (see Auto
Mode discussion for further explanation).
Verify:
• The refrigerator is plugged into a known working AC
outlet supplying a minimum of 85VAC
• The AC power cord is in good operating condition
• The glass 8-amp fuse (F2) on the Power Board is intact
• Replace power board.

NOR000124A-nofl
Meaning:
The Power Board was not able to detect a
fl
ame present at
the burner. This fault, by itself, can only be displayed while
operating in the Manual LP Gas Mode. This fault can be
displayed in conjunction with other faults while operating in the
Auto Mode. For example; no AC followed by no FL (see "Auto
Mode" discussion for further explanation).
Verify:
• All LP gas shutoff valves (including manual shutoff on
gas valve itself) are open
• LP Gas pressure at refrigerator is 11.5” W.C. (water
column)
• LP gas supply line is free of air
• The burner is clean
• The electrode-to-burner air gap is between 1/8” and
3/16”
• The spark-sense igniter wire is installed correctly and in
good operating condition
NX64 / NX84, NXA64 / NXA84 Fault Codes
Meaning:
This fault is a combination of two separate faults. First, the
Power Board sensed the AC input voltage to be less than
85VAC and automatically switched to the LP Gas Mode.
Secondly, the Power Board was then unable to detect a
fl
ame
while operating in the Auto LP Gas Mode. This fault can only
be displayed while operating in the Auto Mode.
Verify:
• Follow the “Verify” instructions for the "no AC fault and
"no FL" fault
• Replace power board.

NOR000124A-opli
Meaning:
This fault means the Power Board sensed the high limit
thermal switch is open. This thermal switch is mounted to the
metal insulation pack mounted above the burner. This fault can
be displayed in ANY MODE.
Verify:
• Is thermal switch electrically open, i.e. has it tripped? If
yes, reset switch.
• If no, verify wiring is connected properly. Refer to
refrigerator wiring diagram "Wiring Pictorial" on page
53 for proper connection.
• If yes, contact Customer Service for further instructions.

• Gas valve solenoid is in good operating condition (Coil

)
• Wires to the gas valve are connected and in good
operating condition
• Power Board supplies 12VDC to gas valve when
required
• Replace power board.
