What could go wrong with a 400F heating element on in your air ducts at all times. Wouldn’t it constantly be lighting hair and dust particles on fire???
One of the primary causes of housefires is leaving bathroom fans running.
[citation needed]. A quick google search shows some warnings about this happening (due to lint and dirt building up and the motor overheating) but I’d be very surprised if it’s even in the top 10.
It's what the firefighter told my parents when the bathroom ceiling fan burned our house down.
Really?? I always do this and now I'm worried, got a source? A normal fan or the fans with the heat lamp bulbs integrated?? Cause I can see those starting a fire with the intense heat it generates.
