Chicago (3-5-2) trailed the entire match until the equalizer. The Fire have played to draws in their past two matches and are winless in four straight.
Kei Kamara struck for Columbus (4-4-3) in the eighth minute, tapping home Ethan Finlay's pass at the top of the 6-yard box for his eighth goal of the season. Kamara scored again in the 55th minute, on a header of a feed from Kevan George.
Quincey Amarikwa had a golden opportunity for the equalizer in the 81st minute, but his right-footed effort from the center of the box off a cross from Accam sailed over the crossbar.
