Cabinet air conditioner

Hello and God's mercy Used cabinet air conditioner needs maintenance (a part in the external motor), I don't know how much it costs.. There is no refrigerant adjustment or anything else except (the part) No remote control I don't know how many tons, approximately 4 tons It was previously maintained and worked properly, but it was replaced due to excessive cooling in the area, another part broke, so I replaced it with a split unit Location: Al-Ahsa, and selling is allowed..
