MADISON, Wis. — A carbon monoxide alarm alerted an east side resident to a problem in their furnace Tuesday night.

According to an incident report from the Madison Fire Department, a resident on Inwood Way looked at the carbon monoxide alarm and found a reading of 224 parts per million.

Officials said the resident unplugged it and hit the reset button before plugging it back in, still finding elevated carbon monoxide levels of 43 ppm.

Firefighters confirmed the presence of carbon monoxide.

The report said MG&E determined the furnace needed repairs and would have to be shut down.

Officials said the resident had another place to stay for the night until the furnace can be replaced.
