# An electric or gas oven should be cleaned from all specks of Chametz and left 24 hours unused. If it has a self-cleaning mode, it should be put on self-clean and that is sufficient.<ref>Rabbi Jachter (Gray Matter vol. 2, p. 221) quoting Rabbi Elazar Teitz, [http://www.crcweb.org/Passover/2016/Pesach_Guide_2016.pdf CRC Pesach Guide 2016 (p. 19)], Yesodei Yeshurun v. 6 p. 156-160, OU Pesach Guide 2016 p. 24, Halachos of Pesach by Rabbi Ribiat p. 354.</ref> However, if it doesn't have self-clean, many hold that the oven can be heated to the highest temperature it reaches for one hour or two and that is sufficient. <Ref>Rav Ovadia Yosef (Chazon Ovadyah pg 73, Sh”t Yechave Daat 2:63), Rav Aharon Kotler (quoted by Rabbi Eider in Halachos of Pesach 1:180), and Rav Soloveitchik (quoted by Gray Matter vol. 2, p. 219) hold that conventional ovens which don't have a self-cleaning setting can be koshered by raising them to the highest temperature that they can reach for an hour or two. | # An electric or gas oven should be cleaned from all specks of Chametz and left 24 hours unused.

Chut Shani Pesach 10:2 writes that the minhag isn't to kosher such an oven but after the fact the koshering is effective. | ||
* Rav Ovadia Yosef explains that according to many rishonim chametz is considered something which is permitted that was absorbed in a utensil that only becomes forbidden over time and as such even items which normally would require libun can suffice with hagalah. Even though Shulchan Aruch O.C. 451:4 holds like the rishonim who hold that chametz is considered like a forbdiden taste all year since on Pesach it will be forbidden and as such libun is necessary on utensils used over the fire, nonetheless, for utensils which can't be koshered any other way and it is difficult not to use the oven all of Pesach, one can rely on the lenient opinion. See Rav Ovadia's responsa for his lengthy explanation. | * Rav Ovadia Yosef explains that according to many rishonim chametz is considered something which is permitted that was absorbed in a utensil that only becomes forbidden over time and as such even items which normally would require libun can suffice with hagalah.

* Rabbi Soloveitchik offered another reason to be lenient. Since chametz only got absorbed through a certain temperature, those absorptions can be removed in the same way that they went in, which is certainly less than the maximum temperature that the oven can reach. This seems to be at odds with the Pri Megadim E"A 451:30 who holds that libun needs to be a certain temperature to burn out the forbidden tastes, but it is supported by the Arugot Bosem 119. Igrot Moshe YD 1:60 s.v. aval and Or Letzion 3:10:2 agree with Pri Megadim. | * Rabbi Soloveitchik offered another reason to be lenient.
