Electricity on Shabbat: Difference between revisions

#If the light is left on and one finds a way to open the refrigerator the food inside isn't mutkzeh.<ref>Shemirat Shabbat Kehilchata ch. 10 fnt. 44 explains that it isn't muktzeh since turning on the light is merely an impediment (Magen Avraham 518:14 from Ran and Rashba Beitzah 31b) and also there are permitted ways to get a refrigerator to open a refrigerator with a light on.</ref>

===Water Coolers and Water Fountains===

# A water fountain that is mechanically operated and the button itself isn't electric may be used on Shabbat as long as the motor for the compressor to cool the water isn't triggered when one is using it. The amount of water one can remove in one time without triggering the motor depends on the water fountain.<ref>[http://www.yutorah.org/lectures/lecture.cfm/742318/Rabbi_Mordechai_I_Willig/Halacha_Engages_Modernity_-_Part_8_-_Electrical_Appliances_(Part_1) Rabbi Willig (min 33-35)] says that using a water fountain on [[Shabbat]] depends on how long it takes for the motor to turn on. He mentions that one shouldn't use a water fountain which clearly will have the motor go on with a single regular use. However, he did not say this as a definitive ruling but in passing. Note that this wouldn't apply to an electric water fountain that triggers a circuit. Regarding Rav Schachter's opinion, see [https://www.yutorah.org/lectures/lecture.cfm/924745/Rabbi%20Ike%20Sultan/Using%20YU%20Water%20Fountains%20on%20Shabbos R' Sultan's note about water fountains at YU].</ref>  

# A water cooler is essentially similar to a refrigerator. If the water is only cooled at certain intervals when the water becomes warm it is permitted to be used. If the water is cooled immediately upon pressing the button it is forbidden.<ref>[https://revach.net/ask/article.php?id=173 revach.net], [https://dinonline.org/2010/05/03/water-cooler-on-shabbos/ dinonline.com], [https://www.zomet.org.il/eng/?CategoryID=250&ArticleID=102].
