Article overview
Burning smells from a range, oven, cooktop, or hood: which ones are leftover manufacturing odor versus stop-use electrical or grease fires.
New-oven smells on the first few heats can be leftover oils. A sharp electrical smell, melting plastic, or smoke from a hood that should be pulling air are different. This article is about cooking appliances, not a dryer belt.
Stop the cycle. If you see smoke at the control, at the back of a range, or from a hood motor area, shut the appliance down. Keep a hood from running if the smell is clearly electrical.
Grease in a hood can smoke during a high-heat sear. That is still a ventilation and filter issue, not a reason to ignore a motor that smells like burning insulation.
When the smell is electrical or the source is unclear, book diagnosis. Independent cooking-appliance service in Los Angeles County and Orange County will inspect rather than guess a part from a smell description alone.
