Kartal had been serving as the assistant coach since 2010, three seasons under Aykut Kocaman and one under Yanal.
Yanal resigned from his post on Saturday, leaving the defending champions without a coach only three weeks before the start of the domestic league after reported difficulties with chairman Aziz Yildirim.
Yanal became the 11th coach to be replaced in the Turkish Super League since the end of last season.
