This could be due to a faulty heating element, a broken igniter (for gas ovens), or a problem with the thermostat or control board. See our guide on how to fix a no-heat oven.

Slow preheating can be caused by a failing bake element, weak igniter, or inaccurate temperature sensor. Also check for power supply issues. For more, read about testing oven temperature accuracy.

An oven that overheats may have a faulty thermostat or temperature sensor, causing inaccurate heat regulation.

Check the power supply, circuit breaker, and that the appliance is properly plugged in. It may also be due to a failed control board or fuse.

Worn or bent door hinges, damaged seals, or food debris around the frame can prevent the oven door from closing completely.

Smoke often comes from food residue or grease buildup. It’s recommended to clean the oven thoroughly before using it again. Learn more in our guide to self-cleaning ovens.

Some noises are normal as metal parts expand with heat. However, repeated or loud clicks may indicate a faulty igniter or relay switch.

This could be due to a locked door switch, control panel failure, or interrupted power. Make sure the oven door is securely latched.

The oven bulb may be burnt out or the light socket or switch could be defective. Replacing the bulb is a quick first step.

Uneven cooking can result from a faulty convection fan, damaged bake or broil elements, or poor rack positioning inside the oven.
