PRODUCT CARE
DEFROSTING
1. Shut off the refrigerator by pressing the main
power ON/OFF button.
2. Empty the refrigerator.
3. Leave the cabinet and freezer doors open and
make sure the drip tray is in place under the
finned evaporator.
Defrosting time can be reduced by filling ice trays
with hot water and placing them in the freezer
compartment.
FIRE AND INHALATION HAZARD. Do not use
a knife, ice pick, or any other sharp tool to
remove frost from the freezer compartment.
Failure to obey this warning could cause a
leak in the ammonia cooling system which
could lead to a fire hazard resulting in death
or serious injury.
An ammonia leak also poses an inhalation
hazard, and could cause chemical burns to
the skin and eyes. Exposure to a high con-
centration of ammonia could result in death
or serious injury.
Do not use a hot air blower to remove frost
from the freezer compartment. Permanent
damage could result from warping the metal
or plastic parts.
4. When all the frost has melted, dry the interior with
a clean cloth and turn the refrigerator back on.
5. Set the thermostat to the coldest setting for a
few hours. Then, reset the thermostat to the
desired setting, usually at mid setting. Replace
food after refrigerator has reached appropriate
cool temperature.
STORAGE PROCEDURE /WINTERIZ-
ING THE REFRIGERATOR
(ICE MAKER MODELS ONLY)
The refrigerator is equipped with a heater tape wrapped
around the water solenoid valve and outlet water tube.
During cold weather operation below 32°F/0°C the au-
tomatic temperature switch will turn the heater tape on
automatically.
If the RV will not be in use for an extended period of time
or put into storage:
• Drain the RV water system.
• Disconnect the water lines from the inlet and outlet sides
of the water valve. Drain the lines into a cup and allow
the lines to dry.
• The ice maker should be drained and dried. Note that
this procedure must be performed by a qualified service
technician.
• Using a lukewarm soda solution, clean the interior
liner of the refrigerator. Clean the finned evaporator
and shelves. Use warm water only and never strong
chemicals or abrasives since these can damage the
protective surfaces.
• Place doors in the airing position.
CLEANING
Always keep the refrigerator clean. Cleaning the refrigera-
tor is usually done after it is defrosted or put into storage.
Use lukewarm weak soda solution to clean the interior
liner of the refrigerator. Use warm water only to clean the
finned evaporator, gasket, and shelves. Do not spray liq-
uid near electrical outlets, connections, or the refrigerator
components.
After cleaning the interior liner/evaporator fins, make sure
thermistor bulb and thermistor bracket are properly posi-
tioned. See "Troubleshooting" on page 14.
Do not use strong chemicals or abrasives to
clean these parts, as the protective surfaces
will be damaged.
To keep the refrigerator operating efficiently, periodic in-
spection and cleaning of several components once a year
is recommended:
• Check the lower vent, upper vent, and area between
these openings for any obstructions such as bird/insect
nests, spider webs, etc.
• Make sure the refrigerator area is free from combus-
tible material, gasoline, and other flammable vapors
or liquids.
FIRE OR EXPLOSION HAZARD. Do not store
or use gasoline, oil or gasoline soaked rags,
or other flammable vapors and liquids in the
service area behind the refrigerator or in the
vicinity of this or any other gas appliance.
Failure to obey this warning could cause a
fire or an explosion resulting in death or seri-
ous injury.
• If accessible, clean the coils on the back of the refrigera-
tor. Use a soft bristled brush to dust off the coils.
