Four units and 18 firefighters responded to 901 4th Ave. NW at about 12:45 p.m. Monday.
When firefighters arrived, they found smoke inside the Hidden River Acres Event Center, Christianson said.
“Two guys went in and noticed it wasn’t hot in there, and then saw the sprinkler head was going off, so they shut the sprinkler system down and then just ventilated the structure from smoke,” he said. “The system put the fire out. It did what it was supposed to do.”
Christianson said the building received minor smoke damage, and the ice machine was also damaged.
Christianson said the cause of the fire was from the ice machine malfunctioning.
No injuries were reported.
Firefighters were on scene for about an hour.
