Ovens are essential appliances in both homes and commercial kitchens, and when they stop working properly, it can cause major inconveniences. Whether you’re a homeowner trying to bake dinner or a restaurant owner relying on high-performance ovens, knowing common oven issues and their fixes can save you time and money. We’ll cover the most frequent oven malfunctions, their causes, and how to fix them.
Oven Not Heating Properly
Possible Causes
- Faulty Heating Element – The heating element is responsible for generating heat in the oven. Over time, it can wear out or become damaged.
- Broken Thermostat – If the thermostat isn’t working correctly, the oven won’t reach the desired temperature.
- Malfunctioning Igniter (Gas Ovens) – In gas ovens, a faulty igniter may fail to light the gas burner.
- Blown Fuse – Some ovens have thermal fuses that can blow due to overheating.
How to Fix Your Oven if its Not Heating
- Check the heating element by turning the oven on and observing if it glows red. If it doesn’t, it may need to be replaced.
- Use an oven thermometer to verify the actual temperature against the set temperature. If there’s a discrepancy, the thermostat might need adjustment or replacement.
- For gas ovens, listen for a clicking sound from the igniter when turning on the oven. If there is no sound or the igniter glows but the burner doesn’t light, the igniter may need replacement.
- Check the fuse box for a blown fuse and replace it if necessary.
Oven Overheating
Causes of Oven Overheating
- Defective Thermostat – If the thermostat isn’t working properly, it may cause the oven to overheat.
- Temperature Sensor Issues – A misaligned or faulty temperature sensor can send incorrect signals to the control board.
- Control Board Malfunction – The electronic control board regulates temperature settings, and if it’s faulty, it could cause excessive heating.
Fix It
- Ensure the thermostat sensor is not touching the oven walls, as this can lead to incorrect readings.
- Test the thermostat with a multimeter. If it’s not working properly, replace it.
- If none of the above solutions work, the control board may need to be checked by a professional.
