DESCRIPTION OF OPERATING
MODES
AESlAUTO
MODE
When operating in the
AES/AUTO
mode, the
AES/AUTO
mode indicator lamp (6) will illuminate. The control sys-
tem will automatically select between AC and GAS op-
eration with AC having priority over GAS. Either the AC
indicator lamp (A) or the GAS indicator lamp (C) will
illuminate depending on the energy source selected by
the control system. If the control system is operating
with AC energy and it then becomes unavailable, the
system will automatically switch to GAS. As soon as AC
becomes available again the control will switch back to
AC regardless of the status of GAS operation.
GAS MODE
When operating in the GAS mode
theAES/AUTO
mode
indicator lamp (6) will be off and the GAS mode indica-
tor lamp (C)will be illuminated. This mode provides LP
gas operation only. The control system will activate the
ignition system and will attempt to light the burner for a
period of approximately45 seconds. If unsuccessful, the
CHECK indicator lamp (D) will illuminate and the GAS
mode indicator lamp(C) will turn off.
To restart GAS operation, press the main power
ONI
OFF button (1) to the OFF and then ON position. The
control system will attempt a new 45 seconds ignition

If the refrigerator has not been used for a long time or
the LP tanks have just been refilled. air may be trapped
in the supply lines. To purge the air from the lines may
require resetting the main power ON/OFF button (1) three
or four times. If repeated attempts fail to start the LP gas
operation, check to make sure that the LP gas supply
tanks are not empty and all manual shutoff valves in the
lines are open. If the problem is still not corrected, con-
tact a service center for assistance.
If the control is switched to AC operation while the
CHECK indicator lamp is on, it will function properly, but
the CHECK indicator lamp will not go off until the main
power ON/OFF button is pressed to the OFF then ON
position.

LIMP MODE OF OPERATION
This control system contains a feature where it will con-
tinue to operate the cooling system in the event of a
failure of a major operating component. Two different
modes of operation can occur in this category
If for some reason the display module becomes non func-
tional, the control system will revert to full automatic
operation selecting the best energy source available with
AC, GAS priority The temperature of the refrigerator
will be maintained at the MID position within normal tem-
perature tolerances. The power module will continually
attempt to reestablish operation of the display module.
The second limp mode of operation will execute when a
failure of the temperature sensing device or associated
electronic circuitry occurs. If this should occur, the con-
trol system will operate on the energy source selected
via the control panel. The cooling unit will run continu-
ously on the selected energy source. The refrigerator
will continue to operate in this mode indefinitely or until
a new sensor is installed and the system is reset.
