Preparatory stage
Before starting repairs, it is necessary to collect as much information as possible about the failed device. Ideally, this is a service manual for a specific model. In this document, the manufacturer provides all the necessary data, starting from the assembly drawing (exploded view) and ending with the algorithm for troubleshooting.


Unfortunately, manufacturers are in no hurry to share this information, distributing it only among networks of certified service centers. If you manage to find technical documentation on repair, be prepared for it to be in English.

If you can't find the documentation, which will happen in most cases, don't worry, typical microwave oven malfunctions can be identified without a schematic diagram. It's enough to know what the main elements look like and where they might be located. A photo of a microwave with the casing removed will help you with this.

The intuitive nature of the process in most cases allows you to remove the casing and get to the main elements of the structure without an assembly drawing. But in this case, you need to remember the sequence of actions and try not to leave "extra" parts after reassembly.

What tools are needed?

In most cases, you can get by with a Phillips screwdriver and a multimeter. In some cases, you may also need a soldering iron. Accordingly, you will also need spare parts, which ones will be clear after diagnostics.
