The refrigerator controls are DC (direct current) operated through an
electronic circuit board. The refrigerator, which operates from heat as
described above, gets its heat source two different ways: an electric heating
element or a flame from LP-Gas. Mode operation and temperature selection is
made by controls on the face of the refrigerator. In order for the refrigerator to
operate the house batteries must be charged, the LP-Gas valve on, the water
valve on (ice maker option only) and the refrigerator AC cord plugged in
(located in outside refrigerator access door). If the controls do not light up,
check the house battery charge status or see if the 12 Volt wires are plugged into the
refrigerator’s circuit board (located outside in the refrigerator access door).
While the motorhome is traveling the ice maker may be operated using the
120 Volt AC electric mode to keep the freezer contents cold. The electrical
combination of the engine’s alternator and the inverter will supply the power
necessary to operate the ice maker on 120 Volts AC. Operating the refrigerator on
LP-Gas when refueling can be dangerous. Use the AC electric mode when in
travel to avoid this situation. Disable this feature when the engine is turned off.
House battery power will be quickly consumed when using the inverter to operate
the ice maker on AC electric. At location, hook to shore power, start the generator
or switch refrigerator operation to LP-Gas. Turn the inverter off when not in use.
To enable this feature:
1. Turn the inverter ON.
2. Turn the ice maker ON. Select AC power operation.
To disable this feature:
1. Turn the inverter OFF.
2. Hook to shore power, start the generator or switch operation to LP-Gas.
NOTE: Use this feature only when the engine is running.
Failure to disable this feature with the engine off will result
in dead house batteries. Hook up to shore power, start the
generator or switch refrigerator operation to LP-Gas.
The refrigerator uses an audible alarm that will sound for the following
reasons:
1. DC or AC voltage is higher or lower than allowed specifications.
2. Refrigerator is set to auto mode and the 120 Volts AC is discontinued.
3. Liquid Petroleum Gas mode fails to light initially or fails to light after
a period of operation.
4. Door has been left open longer than two minutes.
5. The circuit board detects a failure resulting in a code being displayed.
NOTE: If the alarm sounds, note the code in the LED display
and turn the refrigerator off to silence the alarm. Refer to the
manufacturer’s manual for the list of codes and their meanings.
