Common Bosch Microwave Problems and How to Fix Them

At Boscheny, we understand the frustration of using a malfunctioning microwave. Having a Bosch microwave doesn’t make that any easier — these appliances are far from the simplest kitchen tools. But, fear not; with the right approach, it is usually possible to troubleshoot even the most complicated malfunctions to fix them yourself. Below, we will talk about the most common Bosch microwave problems and how to fix them.

Reheating Issues

If the food you’re reheating is not getting done, there are a few potential causes. Your appliance may suffer from insufficient power supply or could be having difficulty regulating the power output. To diagnose and resolve this issue, you should start by checking the power connection and plugging it into a different outlet. If this does not work, next you can try turning the power setting higher or lower. Alternatively, the glass tray may be unbalanced and vibrating, preventing food from heating uniformly. To fix that, simply check the tray and make sure it is placed correctly.

Inoperable Handle

In some cases, the opening and closing handle on a Bosch microwave may become stuck, rendering the appliance useless. This is a relatively common problem, but it is usually quick to fix. Start by looking for any potential build-ups of dust, dirt, or grease that could cause the handle to get jammed. If you don’t find anything, the next step is to clear the tracks and lubricate them with a few drops of cooking oil. You may also need to replace the screws that attach the door handle to the appliance.

Strange Noises

At times, a Bosch microwave may start to make strange noises. This is almost always a sign that an internal part has become faulty. The most likely cause is a failing fan motor, or a magnetron or both, and when these components fail, they can make loud noises. A professional repairman will likely be able to replace them, but this can be costly. Instead, you may want to try unplugging the appliance, allowing it to cool off, and then plugging it back in. This process usually discharges the current, allowing for the fan and magnetron to reset.

Microwave Will Not Turn On

Occasionally, a Bosch microwave may refuse to turn on. If this is the case with your appliance, the first thing you should do is check the power cord for signs of fraying or breakage. If it looks ok, the next step is to check the power outlet, as it may have become loose or broken. It is also possible that the cooling fan has become blocked, preventing the microwave from working at all. You can access and inspect the fan by opening the appliance. Make sure it’s unobstructed and that its rotating freely.

Difficult to Clean

If your Bosch microwave has become stubbornly difficult to clean, its ventilation grille may need cleaning. This can be done with a small brush or vacuum. Next, you should check the air filter, which may have become clogged with dust. This is a very common problem. The filter can be cleaned with a microfiber cloth or rinsed with soapy water. If the grille and filter are extremely dirty, they can be removed and taken outside to be properly washed.


No one likes dealing with broken appliances. This is especially true with complex machines like Bosch microwaves. With our help, though, you should now be able to recognize and fix most of the most common Bosch microwave problems. Remember, if something more serious is going on, it is usually best to call in a professional to handle the job.

Preventive Action to Avoid Bosch Microwave Repair Issues

Local appliance and HVAC technicians in San Diego recommend several preventive actions to help avoid Bosch microwave repair issues. To ensure optimal performance of your Bosch microwave, please consider these itemized recommendations:

1. Clean Regularly:

To maintain the unit's performance, it is recommended to regularly clean the interior. Food residue, oils, and cooking splatters can accumulate on microwaves walls, creating an ideal environment for microorganisms such as bacteria and fungi. This can impact the food being cooked and cause contamination. It is also essential to clean and replace air filters as needed to ensure proper airflow through the unit and avoid potential repair problems.

2. Use Proper Utensils:

Utensils should be microwave-safe when cooking in order to avoid unnecessary damage to the unit. Check the user manual and make sure the cookware materials are listed as suitable for microwave cooking. Generally, plastic and ceramic containers are recommended for microwaves.

3. Avoid Overcooking:

It is important to adhere to the maximum cooking time and temperature recommendations laid out in the manufacturer's guide. Excessive heat and prolonged exposure to it can cause serious damage to the microwave and result in expensive repairs.

4. Check Connections:

It is recommended to check the connections at least once a year to ensure they are secure and in proper working order. Connections can become loose over time due to vibration, so they should be regularly checked and tightened, if necessary, to prevent any problems.

5. Avoid Overloading:

Do not overload the microwave with too many bowls or dishes, as this can cause an electrical overload and could lead to potentially hazardous or costly repairs. Additionally, do not open the door during cooking and keep flammable materials away from the unit.

Following these simple recommendations can help to avoid Bosch microwave repair issues and keep the unit running smoothly and safely. Healthy, delicious meals can be achieved by adhering to these important steps.
