GAS/ELECTRIC OPERATED ABSORPTION REFRIGERATOR HAVING AUTOMATIC FLAME DETECTION AND RESTART CAPABILITY WITH VISUAL INDICATION OF OPERATING STATUS ABSTRACT OF THE DISCLOSURE An absorption refrigerator having a generator selectively heated by an electrically operated resistance heater or a flammable gas operated burner. In the gas mode of operation, a monitor electrode positioned above the gas burner automatically senses the absence of the burner flame and commences a restart sequence to reignite the burner. If reignition fails or the burner cannot be ignited within a predetermined time, further ignition attempts are inhibited and an indicator lamp on the front of the refrigerator enclosure above the freezer door provides a visual indication that cooling is not being supplied to the refrigerator. Different colored visual indicators are also provided to show that the refrigerator is being operated by gas or electricity. In another embodiment, the refrigerator may be selectively operated from alternating current, direct current or flammable gas, with colored indicator lamps showing the type of power source used.
