Hi Hi. Today we will focus on the repair of microwave ovens.
I recommend that you be extremely careful in the repair of microwave ovens!
They contain circuits where voltages can reach up to several kilovolts.
There are not so many signs of malfunction. The first is when the microwave oven seems to be working but not heating.
The second sign is when sparks appear in the working chamber.
The third symptom of malfunction usually occurs among beautiful women. When no button works, nothing turns on. The solution to the problem is very simple. We need to plug this beautiful device into the socket.
For the microwave oven test, I use a damp piece of material.
The wet cloth is completely cold, which means that the high-frequency generator does not work.
Be sure to disconnect the device from the mains voltage!
If you are a beginner, then writing everything down on the phone so that later there will be no problems in reassembling. Put the screws in one place. How many screws and bolts have unscrewed so many and must screw in.
These radios are seen most often fail. This is a regular outline
There are inverter microwave ovens, of course, everything is more complicated there. Capacitor, magnetron and high-voltage fuse.
The step-up transformer never breaks.
Let's start with a high voltage capacitor. paired with a diode. It often fails.
The second thing worth paying attention to is the magnetron. It is also often faulty.
The top three for faults is headed by a high-voltage fuse.
If the microwave oven does not heat up, the first step is to check the high-voltage fuse.
The capacitor already has a discharge resistor, but I strongly recommend that you close the capacitor contacts, preferably through a resistance
There is a malfunction. This is a high voltage fuse
In some cases it can be replaced with the whole circuit working.
Do not be in a hurry to rejoice, it is in some cases such a simple repair comes out.
The fuse blows out for a reason. This means some kind of malfunction in the circuit.
Let's check the capacitor. It is advisable to measure everything on megaohms.
First, I'll check the capacitor for breakdown. As you can see, the charge has occurred. This means that the capacitor between the plates is not broken.
Next, you need to look at the short circuit relative to the case. It's okay too.
It was the turn of the magnetron. I put the tester in the vertebra mode. As you can see, there is no cliff.
Then you need to measure the breakdown relative to the case.
This is a cursory check! Everything is checked much more difficult.
The high voltage fuse is sold on Ali and in any radio store.
Some people start to solder the wire ..
They think that they have selected the right material and calculated the cross section.
Remember, you can't do this fuse costs a penny
Save your life and property by preventing fire or breakdown.
When testing, I recommend placing the appliance cover on the bed.
Don't mess with microwave radiation!
One microwave oven is ready. I don't know, I can see
or not, what material is hovering? I will close.
