Food that is burnt on one side and raw on the other, or baking that takes much longer than recipes indicate, points to uneven oven heating. Causes include a failing bake or broil element, a malfunctioning temperature sensor, a broken convection fan, a door seal that no longer holds heat, or incorrect oven calibration. An appliance-repair technician can test the heating elements, recalibrate the thermostat, replace the convection fan motor, and reseal the door gasket.
