DESCRIPTION OF OPERATING
MODES
AES/AUTO MODE
When operating in the AES/AUTO mode, the AES/AUTO
mode indicator lamp (B) 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 illu-
minate 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 regard-
less of the status of GAS operation.
GAS MODE
When operating in the GAS mode the AES/AUTO mode
indicator lamp (B) 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 make three attempt to light the
burner for a period of approximately 45 seconds with
two minutes interval. If unsuccessful, the CHECK indi-
cator lamp (D) will illuminate and the GAS mode indica-
tor lamp (C) will turn off.
To restart GAS operation, press the main power ON/
OFF button (1) to the OFF and then ON position. The
control system will attempt a new ignition sequence.
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 fail-
ure 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 op-
eration 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.
