# It is forbidden to use a regular elevator on [[Shabbat]]. Some allow using a '[[Shabbat]] elevator' which stops at every floor, while others forbid, and some say one may go up in the [[Shabbat]] elevator but not down. It is forbidden to touch the elevator doors when they are closing. <ref>Shemirat Shabbat KeHilchata 23:29 permits uses a [[Shabbat]] elevator on [[Shabbat]]. Sefer Maliyot BeShabbat (chapters 1 and 7) holds that one may go up in the elevator but not down. Menuchat Ahava 24:15-6 concludes that one shouldn't use the [[Shabbat]] elevator to go up or down unless there is a great need in which case he is lenient to allow going up in the [[Shabbat]] elevator. Rav Yosef Henkin (Edut LeYisrael p. 121) rules that for someone who's weak to do a mitzvah such as daven with a minyan, one can be lenient to use an elevator on Shabbat as long as the non-jew is the one who presses the button and not a Jew. He then says one doesn't need to protest someone who is lenient if the non-Jew is pressing the button, but a pious person (baal nefesh) would be strict. </ref>

# It's permitted to open a refrigerator door when the motor is running as long as the light was disabled from before [[Shabbat]], however, when it is not running it's proper not to open the refrigerator. <ref>
 
* Sh"t Tzitz Eliezer 8:12(4) and 12:92, Eidut LeYisrael p. 122 and 151, Sh"t Minchat Shlomo 1:10, and Shabbos Home (Rabbi Simcha Cohen, vol 2, pg 482) quoting Rav Moshe (even though he was strict in his Teshuvot), Rav Benzion Meir Chai Uziel in Piskei Uziel 15, Rav Joseph B. Soloveitchik quoted by Rav Aharon Lichtenstein (http://www.daat.ac.il/daat/english/journal/broyde_1.htm), and the conclusion in that article is that the minhag among American Jewry is to be lenient.
# Some poskim permit opening a refrigerator door only when the motor already is running, while many poskim hold that one may open the door even if the motor is off. <Ref>
* Sh"t Igrot Moshe 2:68, 4:74, Sh"t Har Tzvi 1:151, Sh"t Chelkat Yacov 3:179 (in new edition 1:77), Sh"t Minchat Yitzchak 2:16 and 3:24, Mishnat Rabbi Aharon 1:4 and Sh"t Az Nidabru 2:36 only permit opening the refrigerator when the motor is running but when it is not running one should not open it.  
* Rav Shlomo Zalman Auerbach (Minchat Shlomo 1:10) permits opening the refrigerator at any time because completing the circuit to run a motor may not involve any melacha at all, and even if it is, it is permitted because it is grama. He says that he’s not sure that it should be considered a psik reisha d’lo nicha lei as one doesn’t want the hot air to cause the motor to run sooner, because one also does want the motor to run so that the food doesn’t spoil. Tzitz Eliezer 8:12:4, 12:92, Rav Moshe Feinstein (quoted by The Shabbos Home vol 2, p. 482; see, however, Igrot Moshe 2:68), Rabbi Mordechai Willig (“Halacha Engages Modernity Part 8,” min 18-22), Rav Benzion Meir Chai Uziel in Piskei Uziel 15, and Rav Joseph B. Soloveitchik quoted by Rav Aharon Lichtenstein (http://www.daat.ac.il/daat/english/journal/broyde_1.htm) agree. Rav Willig commented that the minhag in America is to be lenient.
* Sh"t Yabia Omer OC 1:21 and Menuchat Ahava 24:19 writes that it's very proper not to open the refrigerator except when the motor is running. Shemirat [[Shabbat]] Kehilchata (10:12) recommends setting the refrigerator to a timer. [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 defintive ruling but in passing.
* In defining grama, Rav Hershel Schachter (“Electricity on Shabbos,” min 73-6) explains that according to many achronim who understand grama as a delay in time, it isn’t even a psik reisha to open a refrigerator if the motor will turn on at a later time, while according to Rav Soloveitchik, who defined grama as a total disconnect in action, if it was certain that opening the door would cause the motor to go on any earlier, perhaps it would be forbidden to open the door when the motor wasn’t running based on koach achar m’urev bo. (See B’Ikvei HaTzon siman 7).
* On the other hand, Rav Ovadia Yosef (Yabia Omer 1:21) assumes like Rav Shlomo Zalman that it is grama, but thinks that  completing a circuit may involve an issur deoritta of hav’ara. He also is uncertain if this should be considered a psik reisha d’lo nicha lei and concludes that it is permitted, but it nevertheless is proper not to open the door unless the motor is running. Har Tzvi 1:151, Menuchat Ahava 24:19, and Rav Henkin (Edut LeYisrael p. 122) agree that although it is permitted, it’s proper to be strict.
* Lastly, Chelkat Yaakov O”C 76 argues that while it may be a psik reisha, perhaps it is not considered grama since this is the intended normal way it is used. Therefore, he rules that one may only open the door when the motor already is running. Minchat Yitzchak 2:16 and 3:24, Az Nidberu 2:36, Sh"t Igrot Moshe 2:68, 4:74, and Mishnat Rabbi Aharon 1:4 agree. Shemirat Shabbat KeHilchata 10:12, Orchot Shabbat (vol 3 p. 62), and The Shabbos Home (p. 482) quote the two approaches but do not give a final ruling.
