oomis: an oven with a pilot light may be turned ON on Yom Tov, but may not be turned OFF. It may only be turned lower if there is food on the flame that may be ruined, but even then not completely “
Perhaps you have been taught that way, or did not understand my post, but according to my rov from way back when, ZT”L, respectfully that is not what I was taught. You are correct that TODAY’S ovens absolutely may not be turned on and off, but because the older ovens have a continuous pilot light on them, meaning that the pilot is never affected by the dial turning on or off, it remains burning 24/7, it is NOT m’avreir, but only ma’avir (not creating a new spark, but merely moving an existing flame from one location to another without extinguishing the source), and therefore it MAY be turned on and off on Yom tov. It is only the newer stoves of say the last 20-25 years that actually re-ignite the pilot and extinguish it l’gamrei when the dial is turned off, that are assur to use except in the manner that you describe and with a Sabbath mode. I have checked this out thoroughly with several different Rabbonim, over the years because of all the halachos related to the Shabbos mode type ovens (which I do NOT have – my stove is a 45 year old relic – but was at one time considering buying a new one). I was curious as to why the newer ovens and stove tops were not permissible (I knew nothing about the way they worked), and all the Daas Torah that I consulted said the same thing to me, as I stated, that my particular stove and oven absolutely are permitted to be turned on and off on Yom Tov. If the pilot light accidentally blows out however, I have a halachic problem and can no longer use the burner.
