Based on what you wrote i have a hypothetical question:
Suppose i have a ac running all week long . Goes on at different intervals throughout the day/ night via a 24 hour timer. According to reb moshe would i need to disconnect it before shabbos or can i let it run through out the entire week including shabbos.
I would think assur according to R’ Moshe.
(Bumped because laskern just mentioned this thread and I don’t remember seeing t2’s question)
