• If you have a regular microwave, then instead of an inverter, the transformer may fail.
• Failure of the electromagnetic lamp is possible in ovens of any type.

This can be done this way: insert a regular sheet of paper between the door and the oven. If it fits there quietly, then the connection needs to be adjusted. This is done from the side of the castle. If necessary, tighten it tighter.

• Troubleshooting power surge problems purchasing a stabilizer will help, and if you connect many devices to one outlet, then another outlet.

• Defect in the control unit can also be seen under the back cover. To do this, study all fuses and diodes. If some have obvious differences from others, they must be replaced. After this, the control unit will be restored. An additional sign that requires intervention is a loud noise or rustling sound when turned on.
• If the inverter or transformer breaks down It is best to contact a certified technician. He will be able to accurately determine the causes of the breakdown and only after that will eliminate them or replace the elements with new ones.
• The most difficult failure is related to the magnetron. It is a source of heat. If there is a malfunction in its operation, strong black deposits will be observed on the walls of the oven, and very loud, buzzing or rustling sounds will also occur.
