A common situation: you buy a microwave oven, it serves you faithfully, and suddenly for no reason it stops heating food, although it works. There may be several reasons for this phenomenon.
First, let's look at the simplest causes of a microwave malfunction.
You panic and are going to run away with the microwave to the master (or even buy a new one), and the cause of poor heating may be just a power outage. To be more precise - reducing the voltage in the network. Even minor 20 V can affect the operation of the microwave. The solution to this problem is nowhere simpler: go to an electrician's store and buy a power supply.
Another common cause of furnace malfunction is network congestion. If in the kitchen you have two powerful appliances in one socket, this leads to overload. The solution to this problem: install another outlet so that the devices (if they are forced to work at the same time) use different sources of energy and do not create problems.
The problem of heating food can also be covered in the microwave itself; for example, the oven door is out of order. If the latch in the door of the microwave oven breaks, then it will not be closed tightly, which leads to weak heating or lack of heating. Try to repair the latches or completely replace them with new ones, and then the microwave will warm the food well.
You put a bowl of soup, and it remained cold … Yes, you just forgot to switch the defrost mode to warm-up mode! Check, check! Very often people defrost fish or chicken in the microwave, setting the desired mode for this. But they almost always forget to change it. Then they forget about the defrost mode and shout about the breakdown of the microwave.
There are more complex breakdowns in technology, which will be discussed later.
A common reason why a microwave oven works, but does not heat food, is the disorder of the magnetron. In the second and third place - capacitor and fuse. Often the reason is a transformer breakdown. If you have an inverter microwave, the inverter may be faulty. The timer or the control unit itself could also fail.
If a strong buzz, which you had not noticed before, was added to the lack of heating, then the diode could become unusable. The diode does not pass current in the opposite direction, allowing it to move in only one direction. When this part breaks, the stove makes a loud hum and ceases to heat the contents of the plate. The cause of loud buzzing may be a breakdown of the capacitor, which needs to be replaced sooner. A defect in the magnetron can cause loud noises made by the device when it is turned on.
If it occurred to you to independently diagnose the microwave, remember: even when the device is unplugged, it is still energized. So think twice if you want to take that risk? Better entrust even a simple inspection of the device to a true professional.
