Abstract: A control system for a refrigerator having an absorption cooling arrangement and a generator can include a temperature sensor associated with the generator and operable to sense a temperature of the cooling arrangement, a level sensor associated with the refrigerator and operable to sense a level condition of the cooling arrangement, and a heat source operably associated with at least the generator. A control circuit can include a processor and can be in communication with at least the temperature sensor, the level sensor and the heat source, and can be configured to determine a sensed temperature from the temperature sensor and a sensed level condition from the level sensor. The control circuit can be configured to turn off the heat source based on determining the sensed temperature is below a first predetermined threshold or based at least in part on determining the sensed level condition exceeds a second predetermined threshold.
