Reply To: Opening Door to Air Conditioned Room on Shabbos

I am not so well versed in hilchos grama and psik reisha, but from what I understand: if you cause something to happen, but it wasn’t your intention for it to happen, and it wasn’t a guaranteed direct result of your action then it’s not a problem. Perhaps other people can elaborate… In your case, you had no intention to influence the AC, you were just intending to open the door. Also, the AC isn’t guaranteed to turn on by your opening the door, it may have turned on regardless, or it may not even turn on at all because not enough hot air entered the room.
