Bosch Microwave Not Heating!

The Bosch microwave oven is very easy to use and clean. Furthermore, it saves you a lot of time in the kitchen since it is fast and reliable.

The user manual will aid you in identifying the cause of the problem and how to go about it.

You are likely to come across the following reasons in the user manual:

Why Is Your Bosch Microwave Not Heating?

• The burned-out diode: The function of the diode in the oven is to transmit high voltage to the magnetron to power the magnetron enabling it to heat food. If the diode is defective, the low voltage will be transmitted to the magnetron, which is inadequate to enable it to perform its operations. In most cases, when the diode is defective. It is because it’s burnout. When the diode is burnt out, it will hinder the microwave oven from producing adequate heat needed to power the magnetron to heat the food.
• Malfunctioning door switch-The door switch prevents the oven from operating when the door is left open. Therefore, it is always recommended to ensure that the oven door is closed to allow the microwave to operate effectively.
• Make sure that the foods you are heating in the microwave are recommended to be cooked in the oven: Even though the Bosch microwave oven is a kitchen appliance, not all foods are to be cooked in the oven. Read through the Bosch user guide to ascertain the types of food you need to place in the oven to avoid unnecessary faults.
• Defective high-voltage capacitor: The high-voltage capacitor works with the diode to increase the energy output. This energy is needed to power up the magnetron to enable your oven to heat food. If the magnetron is defective, the magnetron will have insufficient power; therefore, your Bosch microwave oven won’t heat food. You will have to replace the high-voltage capacitor with a new one to enable your oven to carry on with its normal operations.
• Blown thermometer fuse cavity: The thermometer fuse cavity switches off your oven in case it overheats. When your oven overheats, it blows up the thermometer fuse cavity, affecting your microwave oven’s performance. The best option, in this case, is to replace the thermometer fuse cavity to enable your oven to work as usual.

Even if your microwave oven is in good working condition, take the user manual seriously, as it will be your go-to when your oven starts having faults.

• Faulty door switch– When the door switch is faulty, it hinders the oven from performing its normal operations, like heating the food. It is advisable to restore your door switch at your earliest convenience.
• Burnt diode– When the diode is burnt, it is mostly because too much energy is transmitted to the magnetron. The diode may still have the energy to run but no energy to heat food which explains why your oven may not be heating your food but still running. Consider replacing the diode as soon as possible.

It is essential to understand what your appliance needs from you so that when it starts having faults, you can solve them without much strain.
