NX61 / NX81 Fault Codes

The NX61/NX81 model refrigerators have the ability to
recognize various fault conditions and will display a unique
error/fault code accordingly. With the exception of the
thermistor fault which is displayed by fl ashing the cold setting
snowfl ake on and off (while the optical display is awake), all
fault codes are displayed via the power ON indicator and will
be RED in color.
Should the selected heat source input for a particular mode
not be available, the power ON indicator light will be ON
continuously. In other words, the power ON indicator will be
solid RED.

CONSTANT RED INDICATOR LIGHT
The following conditions will cause the power ON indicator to
be solid RED:
Manual AC Mode:
The AC input voltage to the refrigerator was sensed to be less
than 85VAC
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.

Manual LP Mode:
A fl ame was NOT established or a fl ame was NOT sensed
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 / continuity
• Gas valve solenoid is in good operating condition (Coil
resistance ≈74Ω to 92Ω)
• Wires to the gas valve are connected and in good
operating condition / continuity
• Power Board supplies 12VDC to gas valve when
required
• Replace Power Board.
ALL other fault codes will be displayed using fl ash patterns.
The term "fl ash pattern" simply means the power ON indicator
light is turned ON and OFF to create a numeric pattern. These
fl ash patterns directly correspond to particular fault codes.
That is to say, for example, fault code 3 will be indicated by
fl ashing the power ON indicator light RED 3-times, followed
by a 5-second pause, and then repeated as long as the fault
condition is present. See Fig. 4 below.
