Test 12:
Test of the Fan in the Freezer
An open circuit to the fan in the freezer will result in
the display “--”. A blocked fan will result in the display
“bL”. Otherwise the display will show “On” and the fan
is started. A fault here is also indicated with “Er 14”
during normal operation.
Note: Correcting this problem while in this test will not
clear the “--” display. Restart the “Service mode” to re-
fresh the display message. Repeatedly press the SET
button until this test is reached again.
Test 13:
Gas Operation Test
In this test, gas operation may be checked. If the gas
burner and the gas ignition control module are work-
ing OK, the gas ame shall be lit and the display shall
show “FL” (Flame). Before the ame is lit and spark-
ing is on, the display will show “i9” (stands for “ig” and
shall be read as “ignition”). If a fault is detected “--” is
shown.
Note: Correcting a gas operation fault while in this test
will not clear the “--” display. Restart the “Service mode” to
refresh the display message. Repeatedly press the SET
button until this test is reached again.
Note: For model NDE1402 (AC only) this test has no
meaning. “--” will always be displayed during this test.
SECTION 12
12.1 Operation
The refrigerator must be allowed to pre-cool properly be-
fore starting the ice maker. The refrigerator has to be con-
nected to 120 volts AC before the ice maker can operate.
The water line manual shutoff valve (not part of Dometic
unit) must be open. To start making ice, move the ice level
bail arm to the DOWN position.
ICE MAKER
When the ice maker thermostat senses the preset tem-
perature for ejection of the ice cubes, the ngers will start
to rotate dumping any ice cubes and lling the mold with
water. When the storage container is full of ice, the ice
level bail arm cannot return to the DOWN position. This
will stop further production of ice until the container is
emptied and the bail arm is returned to the down position.
The absorption system will keep the compartment at the
proper temperature for storage of ice. Ice making is ac-
celerated if the thermostat is set to the coldest position. It
is a good idea to do this a few hours before you anticipate
a need for ice. The rst few cycles may have small cubes
due to air trapped in the water lines. The rst container of
ice cubes should be dumped if the water system has been
winterized or not used for several weeks.
NOTE: IF THE ICE MAKER WAS CLEANED AND
DRAINED, NO ICE CUBES WILL BE DUMPED INTO
THE STORAGE CONTAINER DURING THE FIRST FEW
CYCLES.
12.2 Mold Heater
The mold heater uses 165 watts to thaw the ice free from
the mold. It is wired in series with the thermostat which
also acts as a safety device. With power to the appli-
ance off, check for resistance between the two leads to
the heater element. You should obtain a reading of ap-
proximately 80 Ohms +/- 10%. If the heater is found to
be defective, replacement of the entire ice making unit is
recommended for proper operation.
12.3 Ice Ejector
The ice ejector blades sweep the ice from the mold cavi-
ties during the ejection cycle. The drive end of the ejector
is “D” shaped for positive coupling. The bearings at both
ends are lubricated with silicone grease. If the ejector
blades are frozen into the ice, defrost the ice maker and
manually cycle the ice making unit, making sure the ejec-
tor stops at the right location.
