What could cause kerosene-like odor from a gas oven/range?
What is happening is called product of combustion. Somewhere around in the house or near the house someone used or opened some sort of stain, paint, varnish or comparable compound including cleaners. The molecules carry over and get mixed in with air and then burned off from open flame. If you light a candle or a lighter you will smell the same odor, although not quite as strong- the bigger the flame the stronger the odor. The odor will dissipate over the next few days until there are no more molecules from the source left in the air.
