Ovens can experience various issues over time. Here are some common oven problems:

1. Uneven cooking: If your oven is not cooking food evenly, it could be due to hot spots within the oven cavity. This can occur if the heating elements are damaged or if the oven's temperature sensor is malfunctioning. You may need to recalibrate the oven or replace faulty heating elements or sensors.

2. Oven not heating: If your oven isn't heating up at all, it could be due to a malfunctioning heating element, a faulty thermostat, or a problem with the oven's electronic control board. Check to see if the heating elements are glowing red when the oven is turned on. If not, they may need to be replaced.

3. Oven not reaching the set temperature: If your oven is struggling to reach the desired temperature, it could be due to a faulty thermostat, a malfunctioning temperature sensor, or issues with the oven's calibration. You may need to recalibrate the oven or replace faulty components.

4. Oven door not sealing properly: A loose or damaged oven door gasket can result in heat loss and inefficient cooking. Inspect the door gasket for any signs of wear, tears, or damage, and replace it if necessary. Adjust or replace door hinges if they are causing the door to not close properly.

5. Oven producing strange odors or smoke: If your oven is emitting strange odors or smoke during operation, it could be due to food spills or residue burning on the heating elements or oven walls. Clean the oven thoroughly to remove any buildup. If the issue persists, it could indicate a problem with the wiring or insulation, and you may need to have the oven inspected by a professional.

6. Faulty oven light: If the oven light is not working, it could be due to a burned-out bulb or a faulty light socket. Replace the bulb to see if that resolves the issue. If not, there may be an issue with the socket or wiring that requires further inspection.

7. Self-cleaning cycle not working: If the self-cleaning cycle is not working properly, it could be due to a malfunctioning door latch, a faulty thermostat, or issues with the electronic control board. Check for any visible damage or obstructions around the door latch mechanism and inspect the wiring and components for any signs of damage.
