– Q. See questions above. If when he changes the place of the mezuza to the other (inside) side of the door’s frame, he gives it to a sofer to check it, does that make a
difference?

A. On question 2824 Horav Shlomo Miller’s Shlit’a opinion is that one does not need to recite a new brocho when replacing a mezuza removed for having it checked, as long as it was removed for a usual and accustomed period of time, even if it more than a day. (Other Poskim disagree).

On question 2425 we wrote: Pischei Teshuva (Y.D. 289: 1) quotes Lashon Limudim that debates whether one should recite a brocho when placing back a mezuza that was taken down to be checked.

Poskim disagree on the above question. Many maintain that one should not say a brocho. (K’sav4 Sofer Y.D. 139, Maharam Shick Y.D. 285, Beis Yitzchok Y.D. 2: 51, and others).
Beis Shearim (Y.D. 370), and others assert that a brocho is needed.

Other Poskim opine that if it is replaced on the same day, no brocho is required. (Shaarei Mezuza 20: 15, Aruch Hashulchan (Y.D. 289: 4), Leket Hilchos Mezuza (4) quoting Horav Vosner and Horav Eliashiv zt”l).

Horav Shlomo Miller’s Shlit’a opinion is that when replaced on a different day, although normally one should reattach the mezuza on the same door frame it was taken from, in this case he should better change it to another one, in order to recite a brocho without any doubt.
