Abstract
An ice maker water supply line is provided with a heater. The heater is controlled by a thermally operated switch. The temperature sensor of the switch senses ambient temperature and operates the heater to prevent freezing of the water supply line. The ice maker is provided in an absorption refrigerator in a recreational vehicle. The supply line runs up the back of the refrigerator in a passage for cooling air flow.
