Operating the Refrigerator Controls(model
N510 )
Control panel:
The refrigerator control panel (see Art10562) is above the
refrigerator door. To maintain the operating control functions of
the refrigerator, a 12 volt DC power supply is necessary. The
refrigerator and any other DC components in the vehicle receive
DC power from the 12 volt system of the vehicle; either an
auxillary battery, a converter, or the vehicle engine battery.
The ON / OFF button [1] starts and shuts down the refrigerator:
- If the refrigerator is shut down, press the ON / OFF button to
start the refrigerator in auto mode.
- If the refrigerator is operating, press and hold the ON / OFF
button for two seconds to shut down the refrigerator.
The TEMP SET button [2] controls the temperature adjustment
of the freezer and the fresh food compartment. The temperature
adjustment that you select does not change if the mode of
operation of the refrigerator changes.
- Push the TEMP SET button and the temperature setting “1-
9” appears in the center display [3].
- Push and hold the TEMP SET button and the temperature
setting changes.
- The number “9” is the coldest temperature setting.
The MODE button [4] controls the operation mode of the
refrigerator.
- Push and hold the MODE button and a light bar flashes in
the center display beside each of the four operating modes
of the refrigerator, one at a time.
- There is one automatic mode of operation and two
(three on model N510.3) manual modes of operation.
- When the light bar flashes beside the mode of opera-
tion that you wish, release the MODE button.
Automatic mode operation:
When you select AUTO mode, the refrigerator controls auto-
matically select the most efficient energy source that is avail-
able for operation. If a more efficient energy source becomes
available, the refrigerator controls change from the current
energy source to the more efficient energy source. The refrig-
erator will not select DC operation.
The controls select the energy source in this sequence:
- When 120 volts AC is available to the refigerator:
- The light bar beside AUTO [5] and the light bar beside
AC [6] show in the center display.
- After ten seconds, the light bar beside AC goes off and
only the light bar beside AUTO remains.
- This means that the refrigerator is operating on AC
electric.
- If 120 volts AC is not available to the refrigerator:
- The light bar beside AUTO and the light bar beside LP
GAS [7] show in the center display.
- After ten seconds, the light bar beside LP goes off and
only the light bar beside AUTO remains.
- This means that the refrigerator is operating on
propane gas.
If an energy source is available to the refrigerator, but is not
operating correctly:
- A fault code appears in the center display.
- The refrigerator controls try to change to a less efficient
energy source.
- If a less efficient energy source is not available:
- The refrigerator stops operation.
- Refer to the “Fault Codes” section of this manual.
Manual mode operation:
When you select one of the manual modes of operation, The
light bar beside the AUTO goes out in the center display and
only the light bar beside either AC, LP, or DC remains.
- AC means that the refrigerator is operating on AC electric.
- DC means that the refrigerator is operating on DC electric.
- LP means that the refrigerator is operating on propane gas.
