Article overview
Why an oven bakes unevenly: heat that is not where you expect, a door that is not sealing, or a control that is not holding a setpoint.
Uneven baking is a cooking result: one side dark, the center raw, or a tray that finishes at two different times. The oven is a cavity. Air, heat sources, and the door seal all participate. This is not a “drum not spinning” problem.
Homeowners can note whether the issue happens in bake, broil, or both; whether the door closes fully; and whether racks were packed so tightly that air cannot move. Do not block vents with foil. Do not assume a displayed code has a published La Cornue meaning we have verified.
If the oven is part of a range and the cooktop is fine, you still have an oven-cavity issue. If the range also has ignition problems, mention both when you book — they may or may not share a cause.
Persistent uneven heat needs temperature and component diagnosis, then a written estimate. That is Oven Repair, not a blog adjustment of the thermostat you cannot safely reach.
