REFRIGERATOR OVERVIEW
DC MODE
RM2354, RM2454, RM2554 & DM2663
When operating in DC mode (3-way models only), the DC
mode indicator lamp is illuminated and all other lamps are off.
To select another operating mode, turn off the DC mode by
pressing the DC selector button. The DC lamp is turned off.
When there is no charging of the house battery, switch to
AUTO mode or GAS mode since running the refrigerator on
12 VDC will quickly drain the battery.
LIMP MODE OF OPERATION
In the event of a failure of a major operating component, the
control system will continue to operate the cooling system.
RM2351, RM2451, RM2551, DM2652 & DM2852
If the control can not read the temperature sensor and control
the preset temperature, the control will run the cooling unit
continuously at the energy source available. The refrigerator
will continue to operate in this mode indenitely - or - until a
new sensor is installed and the system reset.
RM2354, RM2454, RM2554, DM2662, DM2663,
DM2862 & NDM1062
Two modes of operation can occur:
1) The rst limp mode of operation will execute if the display
module becomes non functional. The control system re-
verts to full automatic operation selecting the best energy
source available with AC, DC (3-way only) and GAS
priority. The temperature setting is maintained at the mid
position. The power module will continually attempt to
reestablish operation of the display module.
2) The second limp mode of operation will execute when
a failure of the temperature sensing device or associated
electronic circuitry occurs. If this should happen, the
control system operates on the energy source selected via
the control panel. The cooling unit runs continuously on
the selected energy source. The refrigerator continues to
operate in this mode indenitely or until a new sensor is
installed and the system is reset.
CLIMATE CONTROL SYSTEM
NDM1062
During the summer months of high temperatures and hu-
midity, the metal frame between the freezer and fresh food
compartments may have water droplets forming. The number
of water droplets will increase if the vehicle is not air condi-
tioned during these months. The refrigerator comes standard
with a 12 VDC climate control that will evaporate the water
droplets when they form. The climate control can be left on
continuously or used only when temperatures require it. Note
that when turned on, the climate control will draw 12 VDC
power continuously. Turn it off when a charging source is not
available.
LOW AMBIENT CONTROL
NDM1062
The refrigerator is equipped with an exclusive feature that
allows for trouble-free operation in low ambient temperature
(like below 50°F) for extended periods of time. Once the
outdoor temperature is above 50°F, the low ambient switch
should be turned off.
COLD WEATHER OPERATIONS
Refrigerator performance may be reduced in extremely cold
(subzero) temperatures. This temporary condition is normal
for absorption refrigerators and does not indicate product
failure. In the event that performance is reduced in such condi-
tions, turn the refrigerator off. As ambient temperatures rise,
please restart your refrigerator according to instructions before
requesting service.
THERMOSTAT
RM2354, DM2662, DM2663, DM2862 & NDM1062
The thermostat controls both the gas and electric operation,
thereby eliminating the necessity of resetting each time a
different energy source is employed. After the initial start-up,
the thermostat should be adjusted to the desired temperature
setting.
