You keep asking the same question. In English we say: ON THE LEFT/RIGHT We don't say it differently. Just learn it!

Using the phrase "in the kitchen" implies that that the listener doesn't know that the fridge is in the kitchen but the context clearlly implies that the fridge is in the kitchen so the information about left and right is telling you which SIDE of the kitchen the fridge is on. The fridge is "in the kitchen" and "on a side of the kitchen." Imagine saying "the fridge is on the section of floor to the left side" or "the fridge is on the section of floor to the right side." "there is a fridge on the left of the kitchen" sounds wrong to me "there is a fridge on the left SIDE of the kitchen" sounds right to me "there is a fridge in the left of the kitchen" doesn't make sense "there is a fridge to the left of the kitchen" is correct but means that the fridge is outside the kitchen and to the left of the kitchen "there is a fridge in the back of the kitchen" seems correct to me as well "there is a fridge in the left kitchen" although awkward seems ok but means something different: there are two kitchens and the fridge is in the kitchen on the left. Notice the use of the word "on" in the previous sentence to say "the kitchen on the left." saying "there is a fridge in the left kitchen" is awkward to me because I have not seen two kitchens side by side in which they need to be named "Left" and "Right." Maybe someone who's done food service would have a different perspective. Using the phrase "in the left" makes sense in the following sentence: "The bean is in the left nostril." naming symetrical body parts involves adding left or right, here the words left and right become part of the name and so it makes sense to say the bean is in the nostril or the bean is in the left nostril. "The melanoma is on the left arm" makes sense because the melanoma rests on the surface of the arm. "The carpel tunnel is in the left wrist" makes sense similarly: "Your room is in the left wing" is correct these may be more matters of common usage as much as rules, most english speakers I know don't have anything close to perfect grammar myself included. Please tell me if this was helpful.

Once again, here is the rule for using the prepositions in and on In in mainly denotes “rest at” [ to be located or to be in a specified place] PLACE: He lives in the country. He lives in Chicago. (BUT, He lives at 2300 Wabash Ave.) TIME: I’ll be there in an hour. MANNER: The child ran down the steps in tears. REFERENCE: In my opinion we need a referendum. They are happy in their marriage. On on indicates proximity and position above or outside: PLACE: He sat on the fence. TIME: He was not thinking well on that occasion. REFERENCE: He asked my opinion on the matter. CONDITION: We’ll hire him on your recommendation.

On the left/right side is the correct way of saying it in an english way of describing which side is the location of the thing that you are or other person's talking about.
