While modern technology was intended to make the chores of daily life less difficult, the proliferation of automatic motors, sensors and lights into more household items has become a growing problem for the strictly observant.
For decades, Orthodox Jews trudged through their houses in a pre-Sabbath ritual of turning off home security systems, taping down the button that turns on the light inside the refrigerator when the door is opened, and lighting a flame to leave burning on the stove so food can be heated.
In the last 10 years, manufacturers like Whirlpool and Viking have put Sabbath mode settings on most of their ovens, refrigerators, and even wine cellars. General Electric introduced its Sabbath mode in 2000, and said the special setting is featured on more than 150 of its wall ovens, ranges and other cooking appliances.
