Lo Dc Without Alarm; Lo Dc Without Alarm While In Gas Mode; Lo Dc With Alarm - Norcold 2118IM Service Manual

Fault Codes, cont'd.
Sr
Meaning:
The Power Board detected an internal fault. This fault can be reset
by powering the refrigerator OFF and back ON. Should this fault
continue to be displayed after being reset, the Power Board should
be replaced. This fault can be displayed in ANY MODE.
Verify:
■ Igniter Spark Sense electrode is not touching the burner
(shorted to ground).
■ Wire from P1-10 (12VDC out to gas valve) is not shorted to
ground.
■ For example, if the wire were to be pinched somewhere and
the insulation covering torn, this would allow the bare wire to
short to ground and this fault will be displayed.
■ If the above steps check good and this error continues, replace
the power 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 and
the low DC voltage fault is displayed the divider, perimeter, and
flapper heaters are turned OFF. This fault can be displayed in ANY
MODE. This fault will be cleared and the divider, perimeter, and
flapper heaters will be turned back ON when the DC input voltage
is ≥11.5VDC.
Verify:
■ That the battery charging equipment of the vehicle is opera-
tional.
■ That the AC/DC converter is operational (if applicable).
■ If voltage is within range, replace power board.
Remember that the fault can not be

Lo dc without alarm while in GAS Mode

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 will automatically
reset and the gas valve/igniter outputs will be allowed to operate
once the DC input voltage is >10.5 VDC. This fault can only be
displayed in the Auto and Manual GAS modes.
Verify:
■ That the battery charging equipment of the vehicle is opera-
tional.
■ That the AC/DC converter is operational (if applicable).
■ Contact Customer Service for further instructions.

Lo dc with alarm

code code
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. This fault can be displayed in ANY MODE.
Verify:
■ That the battery charging equipment of the vehicle is opera-
tional.
■ That the AC/DC converter is operational (if applicable).
■ If voltage is within range, replace power board.
