Why an oven may bake unevenly

There are many different reasons. Faulty heating elements, an imprecise thermostat or a defective temperature sensor are often to blame in older appliances. The circulating fan may also deteriorate and, as a result, fail to distribute heat evenly in the cooking chamber. In the case of newer appliances, handling or overloading are more likely the cause. For instance, if multiple baking trays are placed in the oven with the wrong program setting, heat will no longer be distributed correctly.

Yes – in fact, more often that we tend to think. Here are some examples. Choosing the wrong oven shelf, using unsuitable baking tins and overfilling the oven can all lead to inconsistent results. Not reheating the oven properly can also make the difference: a sensitive cake base will respond to temperature variations right away.

You can try this simple test: place multiple slices of bread onto a tray and bake them at 180 degrees Celsius. If the slices turn brown at different speeds, heat in the oven is spread unevenly. An oven thermometer can also help. It shows whether the appliance actually reaches the temperature displayed.

As soon as technical components are affected. For example, if a heating element is no longer working, the fan fails to spin or the temperature display differs substantially from the actual temperature in the appliance. These cases call for an expert. Our technicians will check the appliances on site, install replacement parts or carry out comprehensive maintenance. This way, the oven will stay not only reliable but energy-efficient too.

A bigger role than many people realise. Burnt-on grease stains and food remains can affect heat radiation, while a dirty fan can prevent air circulation. Regular cleaning is therefore important not just for hygiene but also for uniform heat distribution.

Sometimes, yes. In the case of old appliances, components such as heating elements or thermostats eventually break down. But newer ovens can also be affected, such as if a fan is blocked or food deposits have accumulated. Modern appliances, however, like those offered by SIBIR, are equipped with precise temperature controls and sophisticated hot-air systems that ensure even results.

An oven that needs longer to cook all parts of a cake, for example, automatically consumes more energy. So repairs are worthwhile in a number of ways: they extend the lifespan of the appliance and protect your budget and, of course, the environment. Around 70 percent of all appliances can be repaired. SIBIR is particularly proud of this figure. After all, sustainable use also means conserving resources.

Yes, here are some tips:

• Don’t forget to pre-heat the oven.
• Put baking trays on the right shelf.
• Choose suitable oven shelves and baking tins.
• Don’t overfill the appliance: a full oven has less room for air to circulate.

Ovens that bake unevenly usually do not require any major repairs. But special care should be taken: the problem should either go away with minor adjustments or it calls for professional support from the SIBIR all-brand service, which has successfully helped customers throughout Switzerland. This way, you can enjoy the consistent baking results you expect – delicious and cooked to perfection.
