DESCRIPTION OF OPERATING MODES
AUTO MODE
When operating in the AUTO mode, the AUTO mode indicator lamp (A) will illuminate.
The control system will automatically select between AC and GAS operation with AC having priority over GAS. 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 operation.
Gas operation (120 volts AC is not available). The control system will activate the ignition system and will make three attempt to light the burner for a period of approxi- mately 45 seconds with two minutes interval. If unsuc- cessful, the CHECK indicator lamp (B) will illuminate.
To restart an ignition attempt with the CHECK lamp illu- minated or to clear (turn off) the CHECK lamp, press the main power ON/OFF button to the OFF and then ON position. The control system will attempt a new ignition sequence.
If 120 volts AC becomes available while the CHECK in- dicator lamp is on, the CHECK lamp will not turn off until the main power ON/OFF button is pressed to the OFF then ON position.
GAS MODE
When operating in the GAS mode, the AUTO mode indicator lamp (A) will be off. This mode provides LP gas operation only. The control system will activate the igni- tion system and will make three attempt to light the burner for a period of approximately 45 seconds with two min- utes interval. If unsuccessful, the CHECK indicator lamp
(B) will illuminate.
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.
LIMP MODE OF OPERATION
This control system contains a feature where it will con- tinue to operate the cooling system in event of a failure of a major operating component.
If the control cannot read the temperature sensor and control to the preset temperature, then the control will run the cooling unit continuously at the energy source available.
The refrigerator will continue to operate in this mode in- definitely or until a new sensor is installed and the sys- tem is reset.
