PREVENTATIVE MAINTENANCE
An annual maintenance check is strongly recommended:
■ Leak test the gas lines.
■ Check combustion seal; repair or replace, if necessary (Visual
check without removing the refrigerator.).
■ Inspect and clean the burner tube.
■ Check/adjust the spark electrode gap to 1/8 - 3/16 inch.
■ Make sure the spark electrode tip is clean and that the spark
electrode is securely attached to the gas train assembly.
■ Check/adjust AC and DC voltages and propane gas supply
pressure.
■ Check the gas safety valve (see procedure in this manual).
■ Make sure that area around the burner and controls is free of
debris, oily rags, etc.
■ Inspect the controls, piping and wiring to insure that they are in
good condition.
THESE MAINTENANCE PROCEDURES MUST BE PERFORMED BY A
QUALIFIED SERVICE PERSON.
NORCOLD CANNOT ACCEPT RESPONSIBILITY FOR REPAIRS,
ADJUSTMENT, OR MAINTENANCE PERFORMED BY OTHER THAN A
QUALIFIED DEALER OR SERVICE CENTER.
Gas Flame Appearance
While in propane gas operation, examine the appearance of the
gas fl ame:
If the fl ame appears at any of the open-
ings of the burner tube other than the
slots, the inside of the burner tube is
obstructed. Clean the burner tube.
1. Change the refrigerator controls to the coldest temperature
setting.
2. Open the lower intake vent.
The burner door can be hot. Wear gloves
to avoid burns.
3. Open the burner door and look at the gas fl ame:
■ The fl ame should be a darker blue inside and a lighter blue
outside and should be a constant and steady shape.
■ The fl ame should not be yellow and should not have an er-
ratic and unstable shape.
■ Make sure the fl ame does not touch the inside of the fl ue
tube.
4. Close the burner door.
5. Clean the burner tube as part of routine maintenance. Fol-
low the instructions in the “Clean the Burner Tube” topic in
this manual If the fl ame is not at peak performance, after the
burner tube is cleaned, contact Customer Service.

Low Ambient Heater (optional)
Some models are factory equipped with a low ambient heater.
This supplies DC voltage to the heater any time the ambient tem-
perature is low enough. Extended storage during cold weather will
drain the vehicle batteries. To prevent battery drain, remove the 3
Amp fuse from the low ambient heater.
Freezer Blower and Switch Assembly (optional)
All ice maker models are equipped with an ON/OFF switch on the
freezer compartment blower. The switch is factory set to the ON
position. This provides the most ice production. The owner may
choose to turn the blower switch OFF, which will eliminate the
blower noise and also reduce the ice production.
■ With the switch in the ON position, the blower will run continu-
ally.
■ With the switch in the OFF position, the blower will not run.
If DC voltage is present through the wire harness to the switch
and the switch will not turn the blower ON/OFF, replace the freezer
blower and switch assembly.
Electrical Components cont’d.

Temperature Control System
Although the refrigerator is not frost-free, it is made to limit frost on
the cooling fi ns. At regular intervals, the temperature control sys-
tem automatically melts most of the frost from the cooling fi ns. The
water from the cooling fi ns drains into a collection cup attached to
the back of the refrigerator. The heat of the cooling system evapo-
rates the water from the collection cup.
Backup operating system
This refrigerator has a backup operating system. The backup
operating system allows the refrigerator to continue to cool if the
thermistor of the refrigerator should fail.
If this failure occurs:
■ The refrigerator automatically changes to the backup operating
system.
■ In ANY mode, the temperature setting will fl ash ON and OFF for
10 seconds when the control is “awake”
■ The backup operating system can over-freeze or thaw the con-
tents of the freezer and the fresh food compartment.
■ Make sure the temperatures of the freezer and the fresh
food compartment are satisfactory.
