Owner errors. This may be due to incorrect choice of mode (defrosting instead of heating), contamination of the mica plate (it is better to clean it once a month).
The door does not fit tightly. Try placing a sealed piece of paper in the microwave to check the seal. If you find a problem, it is better to go to a workshop.
Decreased magnetron performance. It can only be replaced, but not repaired.
Insufficient mains voltage. This usually occurs in the evening. You can measure the voltage using a multimeter (tester). If there are constant voltage fluctuations, purchase a stabilizer.
Timer operation is faulty. If it is mechanical, then you will have to get used to the features of its operation, but the electronic unit can be replaced.
Deterioration of the tightness of the contacts of electrical elements. That is why it happens that the block or board starts working only from time to time.
Inverter failure. When it switches to very economical mode, the heating level decreases.
