A blown motor in a rooftop heating and cooling unit is to blame for a thrift store being evacuated and an intersection to partially close in downtown Kewaunee Wednesday morning. Kewaunee Police and Firefighters from Algoma and Kewaunee were on the scene before 11 a.m. at the corner of Ellis Street and Milwaukee Street after the Lakeshore Community Thrift Shop filled up with smoke following a power outage. Kewaunee Fire Chief Joe Nemecek said afterward that they found the issue was related to the malfunctioning rooftop HVAC unit. The building was checked out by firefighters for other potential issues and they found nothing else. The scene was cleared before 11:45 after firefighters helped ventilate the smoke out of the building.
