Oven or stovetop not heating, or heating unevenly

Likely cause

A failed heating element/igniter, or a faulty thermostat or control board.

What to try first

• For electric ovens, look for a visibly glowing element when on — if it stays dark, that element has likely failed.
• For gas ovens/stovetops, check whether the igniter clicks or glows at all — a weak/silent igniter is the most common cause.
