REFRIGERATOR OVERVIEW
DC mode
RM2354, RM2454, RM2554 & DM2663 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 V DC 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.

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 indefi nitely - or - until a
new sensor is installed and the system reset.

Two modes of operation can occur:
1) The fi rst limp mode of operation will execute if the display
module becomes non functional. The control system reverts
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 opera-
tion 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 con-
trol system operates on the energy source selected via the
control panel. The cooling unit runs continuously on the se-
lected energy source. The refrigerator continues to operate
in this mode indefi nitely or until a new sensor is installed
and the system is reset.

During the summer months of high temperatures and humidity,
the metal frame between the freezer and fresh food compart-
ments may have water droplets forming. The number of water
droplets will increase if the vehicle is not air conditioned dur-
ing these months. The refrigerator comes standard with a 12 V
DC 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 V DC power continuously.
Turn it off when a charging source is not available.
LOW AMBIENT CONTROL
DM3862, NDM1062 & NDR1292 DM3862, NDM1062 & NDR1292
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 out-
door temperature is above 50°F, the low ambient switch should
be turned off.

The thermostat controls both the gas and electric operation,
thereby eliminating the necessity of resetting each time a dif-
ferent energy source is employed. After the initial start-up,
the thermostat should be adjusted to the desired temperature
setting.
