Operating the Refrigerator Controls
(N64X, N64XXX, N64XIM, N64XIMXX, N84X,
N84XXX, N84XIM, and N84XIMXX models)
Control panel:
The refrigerator control panel (See Art01018) is between the
freezer compartment and the fresh food compartment. A 12 volt
DC power supply is necessary for the control functions of the
refrigerator to operate. The refrigerator receives DC power from
the 12 volt system of the vehicle; either an auxiliary battery, a
converter, or the vehicle engine battery.
The ON / OFF button [1] starts and shuts down the refrigerator:
- To turn on the refrigerator, push and release the ON / OFF
button.
- To turn off the refrigerator, push the ON / OFF button for two
seconds and then release.
The TEMP SET button [3] controls the temperature adjustment
of the freezer and the fresh food compartment. The temperature
adjustment that you select does not change if the operation
mode of the refrigerator changes.
- Push the TEMP SET button and the temperature setting (the
numbers “1-9”) show in the center display [4].
- The number “9” is the coldest temperature setting.
- After a few seconds, the light bar beside AC goes off
and the light bar beside LP GAS [6] shows.
- After 10 seconds, the light bar beside LP GAS 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 shows 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:
- A fault code shows in the center display.
- Refer to the “Fault Codes” section of this manual.
Set the controls to manual mode operation:
- Push the ON / OFF button to turn the refrigerator on.
- Push and hold the MODE button until the light bar shows
beside AC [4] and then release.
- This means that the refrigerator is operating on AC
electric.
- Push and hold the MODE button until the light bar shows
beside LP GAS [6] and then release.
- This means that the refrigerator is operating on
propane gas.
If the energy source is interrupted:
- A fault code shows in the center display.
- Refer to the “Fault Codes” section of this manual.
Cooling unit sensing:
The controls have the ability to sense the operation of the
cooling unit. If the controls sense that the cooling unit has
stopped cooling:
- The heat sources to the cooling unit are turned off and are
locked out by the controls.
- A fault code “n” shows in the Center display.
You can reset the controls and remove this fault code one time.
To reset the controls, shut off and then start the refrigerator.
- To turn off the refrigerator, push the ON / OFF button for two
seconds and then release.
- To turn on the refrigerator, push and release the ON / OFF
button.
If you reset the controls and the fault occurs again before the
refrigerator completes a full cooling cycle:
- The heat sources to the cooling unit are turned off and are
locked out.
- A fault code “n” shows in the Center display.
- This time you can not reset the fault. Have the refrigerator
serviced by your dealer or a Norcold authorized Service
Center as soon as possible.
