Most ovens make a low level of noise when in use. This is especially true if you are using a microwave oven and specifically its microwave function. In this case, the sound is coming from the magnetron that produces microwaves, which is completely normal and is nothing to be worried about. However, some noises can indicate a problem with your oven, and below we have identified some of the more common faults that can cause excessive noise from your oven.
The fan element is dirty
Over time, grease can build up on the oven fan, making it work harder to keep up to speed. If this is the issue, ensure that you give it a good clean in order to get it working as it should. If the problem is not a dirty fan, a replacement may be necessary. We recommend booking a repair with one of our highly trained and qualified Bosch engineers.
The fan motor is damaged
If your oven fan is working slower than normal and is making a louder noise than normal, it could be damaged. Another indicator of the issue is if your oven light is on and the heating element is working, however the oven is not as hot as it should be or the food is cooked unevenly. If the fan motor is damaged, its air circulation is ineffective. In this case we recommend booking a repair with one of our highly trained and qualified Bosch engineers.
The gas igniter won’t stop ticking
This is a common issue, which is actually coming from your gas igniter and not your oven. It generally occurs after you have cleaned your appliance and is usually nothing to be worried about. If excessive water gets into the igniter it will short out and continue to make a non-stop clicking noise. Once the water has been removed, usually through evaporation, the igniter will return back to normal and stop making a ticking noise. However, if your ignition switch is broken, it will not stop making the clicking noise and you will need book a repair with one of our highly trained and qualified Bosch engineers.
