NX64 / NX84, NXA64 / NXA84 Fault Codes - cont'd
dc rE
code
Meaning:
The DC heater relay contacts of relay K1, on the DC Board,
are stuck closed. This fault can be displayed in ANY MODE.
• Replace the DC Board
Lo dc without alarm
code
Meaning:
The Power Board has determined the DC input voltage is less
than 10.5 VDC. Anytime the DC input voltage falls below 10.5
VDC the low DC voltage fault is displayed and the divider
heater is turned OFF. This fault will be cleared and the divider
heater will be turned back ON when the DC input voltage is
≥11.5VDC. 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)
• If voltage is within range, replace power board

NX6 / NX8 / NXA Models
Lo dc with alarm while in LP Gas Mode
code code
NOR000124A-dcre
Meaning:
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
code code
• That the AC/DC converter is operational (if applicable)
• Contact Customer Service for further instructions.
NOR000124A-lodc-woalarn
Lo dc with Alarm
Meaning:
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)
• If voltage is within range, replace power board
