Why does my propane oven emit a chemical smell when in use?
Pull the oven burner and check for lint or any thing that could partially block the air inlet at the burner venturi. If you can see the flame, It should be blue and have a definite pattern not yellow and lazy. My last home had propane for cooking and the stove required more than normal maintenance. If the odor is a "burn your nose or eyes" kind of odor that usually means not enough combustion air at the flame, and a weird smell is what you get. – d.george 6 hours ago
