LG refrigerator 13 cubic feet, used. It has a defect where it sometimes cools strongly, and sometimes cools weakly, which spoils the food inside the refrigerator. I contacted a technician who works at LG. After inspecting it, he said it needs freon ventilation (I didn't understand him frankly), but he told me he can fix it and give me a six-month warranty on the repair for (650 SAR). Selling to the highest bidder. Location: Makkah Al-Mukarramah, Al-Rusaifah district.
