Uneven results frustrate every baker. The cause is usually heat distribution, not your technique.
Check for a Weak Element
An element that only partly glows heats the cavity unevenly.
Fix: Watch it preheat; replace any element that does not glow uniformly.
Verify the Temperature Sensor
A drifting sensor lets the real temperature swing around the setpoint.
Fix: A technician can test the sensor resistance and replace it if off-spec.
Mind Air Circulation
Overcrowded racks and foil-lined shelves block convection.
Fix: Leave space around pans and never line racks with foil.
