Symptoms
- Vent area near the control panel feels very hot to the touch
- Steady odd smell coming specifically from the vent
- Kitchen heats up more than expected during baking
- Vent area discolored or warped
Likely causes
- CommonNormal venting of oven heat and cooking odors, which is by designAll ovens vent some hot air and cooking smells through a vent near the control panel or under a burner.
- CommonWorn door gasket letting excess heat escape past the seal and out the ventA failing seal increases the amount of heat that escapes rather than staying in the cavity.
- PossibleFood debris or grease inside the vent path burning and smellingGrease that migrates into the vent ducting can smoke and smell when heated.
- Less commonInsulation degrading inside the oven cavity wallsAging or damaged insulation can let more heat escape into the vent path than intended.
What to do
- Compare how hot the vent area feels during a normal bake to what you remember from before, since some warmth is always normal.
- Check the door gasket for wear, gaps, or looseness that could be letting excess heat escape.
- Clean around the vent opening of any visible grease or debris buildup.
- Test the door seal with the paper test at multiple points around the door.
- Replace the door gasket if it shows wear, which is a simple and affordable fix.
- Monitor whether the smell is a typical food odor or something more unusual like an electrical or burning-dust smell.
- If the vent still runs unusually hot after a new gasket, have a technician check the cavity insulation.
