iacisrmma, are you certain your rov told you “Only rooms that you know had chametz brought into them need to be cleaned”?
Is it possible he told you, “Rooms that you are certain you did not bring in chometz – do not need to be cleanned”, maybe that is what the rov said? There is a huge difference!
In any event the accepted halacha is we also do bedika in such rooms, as stated at http://hebrewbooks.org/pdfpager.aspx?req=46447&st=&pgnum=115&hilite=
“All places that are used throughout the year that there is a possability that chometz was brought into them, require bdika. FN1. And even places that one is certain that chometz was never eaten there, still require bedika, because we are concerned that he entered these places while eating with chometz in hand and he forgot the chometz there.FN2”
FN 1 – S.A s. 431.ss.3 etc.
FN2 – Rav S,A. ss. 13, Kaf Hachayim ss. 25.
Also you wrote, “If you never move your stove or refrigerator you dont have to move them to clean for pesach (as I heard from the poseik).”
I am certain you have a reliable possek, but maybe you misunderstood him, because that is not the accepted halacha as stated in
http://hebrewbooks.org/pdfpager.aspx?req=46447&st=&pgnum=135&hilite=
“A fridge, if it isn’t too much of a bother to move it from its place and check below it, one should do a bedika there on eve of 14 by candle as normal, but since it is difficult to do so much all on eve of 14, it is enough to clean the area beneath them well, preferably one should do so several days before pessach, by moving them from their place and cleaning there, and before returning to their place, to do a bedika at night by candle.” (Clearly the fridge must be moved, but no need to do so on eve of 14, it can be done prior, both to clean it and then to do a bedika under fridge).
I only write this so that other readers shouldn’t follow the halachos you posted without consulting a reliable possek.
