An overheated furnace prompted the evacuation of a Gig Harbor church this morning, according to Gig Harbor Fire & Medic One.
The incident started about 9:30 a.m. when firefighters were called to Chapel Hill Presbyterian Church after people spotted smoke in the building.
Crews could not find flames so they removed an area of sheet rock from a wall and part of the ceiling to check whether there was a fire in the attic, spokeswoman Nanette Tatom said.
The cause was later determined to be a malfunctioning temperature switch that prevented the furnace from shutting off and caused it to overheat.
No one was injured. The church campus remains closed.
