Oven Temperature Uneven

Hot spots, undercooked centers, or an oven that will not hold the set temp

An oven that burns one side of the tray and leaves the middle raw, or runs way above and below the setting, is frustrating. A drifting temperature sensor, a weak bake element or igniter, a convection fan that stopped, or a worn door seal can all do it without the oven going fully cold. A little variation is normal. Big hot spots that show up every time need a diagnosis.

We fix ovens that heat unevenly, Monday through Friday, 8:00 AM to 5:00 PM. We work out of 140 San Pedro Rd, Daly City, CA 94014, and come to you; there’s no walk-in counter. Call or text (415) 585-5900 or email service@bayappliancerepair.com. California BEAR #46247.

Common causes (high level)

Uneven baking doesn’t mean you need a new oven. Usually the sensor reads wrong, one element is weak, the convection fan has stopped, or the door gasket leaks heat at a corner. On gas ovens it can also be a weak igniter or the bake burner. If the oven doesn’t heat at all, start with the no-heat guide.

• Temperature sensor out of calibration or touching the wall
• Weak bake or broil element (electric) or weak oven igniter (gas)
• Convection fan that does not run or runs noisily
• Door gasket gaps, hinges that will not close, or glass packs that leak heat
• Control board that mis-cycles elements after a power blip
• Blocked vents or foil on racks that upset designed airflow

No heat at all? See oven not heating. Burners on the same range won’t light? See gas stove won’t light. Brand pages: GE, Whirlpool, KitchenAid, Bosch, Samsung, Thermador and Viking.

Safe checks you can do before calling

Observation only. Gas valves, orifices, and live 240V panels are technician territory:

• Bake a simple test (cookies or a flat tray of biscuits) on the center rack; note which side browns first.
• Confirm you are not covering racks or the floor with foil in a way that blocks vents.
• Inspect the door gasket for flattened or torn sections; wipe crumbs from the seal.
• Listen for the convection fan on a convection bake setting if your model has one.
• Note any error code on the display and whether broil still works when bake seems weak.

Do not bypass door locks on self-clean models, prop a gas oven door open as a heat “fix,” or pull a wall oven from the cabinet alone on a 240V circuit. Smell gas? Leave and call your gas utility or a technician. Electric range panel work is not DIY.

When to call for oven repair

Call when food repeatedly burns on one side and undercooks on the other, an oven thermometer disagrees with the set point by a wide margin, convection never runs, the door will not seal, or codes return. Truly cold ovens should follow oven not heating. Appointments run Monday–Friday, 8am–5pm.

What to expect on a visit

We check bake, broil and convection, test the sensor and the heat source, look at the door seal and fan, and go over the options before ordering parts. A sensor, element, igniter, fan or gasket fixes many uneven ovens when the cavity is sound. Qualifying repairs include 90-day parts and labor.
