Place flour in a large bowl or dish. Add chicken, 1 piece at a time; toss to coat. In a large skillet, brown chicken in oil on both sides.
Meanwhile, place the potatoes, carrots, mushrooms and chiles in a greased 5-qt. slow cooker. In a small bowl, combine the remaining ingredients. Pour half of soup mixture over vegetables.
Transfer chicken to slow cooker; top with remaining soup mixture. Cover and cook on low for 3-½-4 hours or until a thermometer reads 170°.
