Oven Not Heating Evenly? What's Going On (Lynn, MA Guide)

Uneven baking — cookies burnt on one side, cakes that sink in the middle — is usually a sign of a heating or airflow issue rather than something wrong with your recipe.

On electric ovens, a bake or broil element that's starting to fail often glows unevenly or in patches rather than a solid orange line. On gas ovens, a partially clogged igniter can cause the flame to burn unevenly across the burner.

Convection ovens rely on a fan to circulate hot air, and a weak or failing convection fan motor will create hot and cold spots even if the heating element itself is fine.

It's also worth checking your oven's calibration. Most ovens run a bit hot or cold from the factory, and this drifts further with age — an oven thermometer left inside for a full preheat cycle can confirm whether the display temperature matches reality.

If the temperature swings are more than 25–30 degrees or one side is visibly not heating, it's time to have the sensor, element, and igniter checked by a technician.

This applies whether you're in Lynn, Peabody and Salem, or anywhere nearby on the North Shore — the troubleshooting steps are the same everywhere.
