Door Alarm (N64X, N64Xxx, N64Xim, N64Ximxx, N84X, N84Xxx, N84Xim, And N84Ximxx Models ); Moisture Reduction Heater; Temperature Control System; Backup Operating System - Norcold N621 Owner's Manual

Door alarm:
(N64X, N64XXX, N64XIM, N64XIMXX, N84X, N84XXX,
N84XIM, and N84XIMXX models)
The refrigerator has an alarm to alert you if the fresh food
compartment door is not closed. The refrigerator continues to
operate, but if the fresh food compartment door is open and the
interior light remains on for two minutes:
- An audible alarm starts.
- "dr" appears in the center display.
- The interior light automatically turns off.
Close the door to silence the alarm.

Moisture reduction heater:

The refrigerator has a heater that prevents moisture from
forming on the center divider between the doors of the freezer
and the fresh food compartment. The heater operates only
when the refrigerator is ON and the DC power is sufficient.

Temperature control system:

Although the refrigerator is not frost -free, it is made to limit frost
on the cooling fins. At regular intervals, the temperature control
system automatically melts most of the frost from the cooling
fins. The water from the cooling fins drains into a collection cup
that is attached to the back of the refrigerator. The heat of the
cooling system evaporates the water from the collection cup.

Backup operating system:

This refrigerator has a backup operating system. The backup
operating system allows the refigerator to continue to cool if the
temperature sensor of the refrigerator should fail.
If this failure occurs:
- The refrigerator automatically changes to the backup
operating system.
- When you push the TEMP SET button, the temperature
setting flashes in the center display for ten seconds.
- After the temperature setting flashes, the mode of
operation appears in the center dispaly.
- The backup operating system can overfreeze or thaw the
contents of the freezer and the fresh food compartment.
- Make sure the temperatures of the freezer and the fresh
food compartment are satisfactory.

models)

Control panel:

The refrigerator control panel (see Art01019) 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 one
second and then release.
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.
