ABSTRACT:
An automatic control system for an absorption refrigerator in a vehicle, such as a recreational vehicle, which is connected to a motor-driven generator. The refrigerator is operated alternatively by either 110 A.C. voltage, 12 volt D.C. voltage, or by gas. If gas is only available, the refrigerator is automatically operated by that means, however, the ignition of the gas burner is prevented when the vehicle is stopped in a filling station and the generator ceases to operate. The arrangement has means which delays the closing of a circuit through a control system after another circuit, including a heating cartridge, has been interrupted.
