When your oven will not heat or bakes unevenly, the cause depends on whether it is gas or electric. Here is what to look for.

Electric oven: bad bake element

If the element does not glow bright orange, or has visible blisters or breaks, it needs replacing. This is one of the most common electric-oven repairs.

Gas oven: weak or failed igniter

A gas igniter that glows but never gets hot enough to open the gas valve will not light the burner. Igniters are a wear item and a routine replacement.

Faulty temperature sensor

If your oven heats but the temperature is way off, the sensor may need testing or replacement. An oven thermometer helps confirm the problem.

Control board or thermostat

No power to the element or igniter can point to a failed control board. This is a diagnostic step for a technician.
