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.
