Despite its reliability, the product is not protected against the inevitable technical glitches. At some point, it just stops working. The main reason is failure of the high-voltage diode.
The high-voltage diode - a few parts, serially connected to each other in a common housing. The package includes a special rectifier diode. This product is endowed with a non-linear current-voltage characteristic of the technical.
Such detail microwave can not be measured in the usual tester, you need to use a multimeter.
Then, make a visual inspection of the microwave. If not melted seats, darkened areas, it is necessary to use a special measuring instrument.
Mechanism works on the same principle. But now many varieties of this element. In the construction a microwave oven has a board with a marking. The desired element is generally denoted DB 1 symbol.
As soon will understand, which model applies your microwave, you can replace the item in a similar element. Marking will be different, but the type of the product is the same. It's just that each manufacturer has its own marking system.
To assess the status of an important part of the need to use a special device - the meter.
After razogrevatelnuyu disconnect equipment from the power supply and eject the furnace element must be turned part. This will allow to measure the voltage on both sides.
Resistance is measured in both the forward and reverse direction.
Checking high-voltage capacitor multimeter is only possible on the breakdown. If the instrument will show a short circuit - part must be replaced.
Neutral tester as we understand there is not suitable. Since the highest limit of measurement of resistance is equal to 2 MW, such a device will always show in this case, "open" circuit.
If you choose to measure yourself, you must know how it works correctly.
Considering the listed data, it can be concluded that the high-voltage diode in a microwave oven is faulty and must be replaced with a new element. After replacing the microwave oven element will function as new.
When checking the resistance on both sides, it is important to know: the conclusions are different purpose and connection.
Element of the mechanism with the + sign bears the marking and ends at the end of the bolt - is the anode.
At the output of the sign - there are connections to the capacitor, and it ends with a bracket - a cathode.
If the microwave band is not the fault of high voltage diode, repair and overhaul independently carry out will be difficult.
Well, I know how the testers and multimeters, which, in fact, one and the same, and that is a high voltage pillars of our such KTS201 that compact import, recruited from several to a dozen, series-connected high-voltage diodes. And by the first checked second.
Because using the above tips author of the article is likely to have risen to a standstill. For it is written, to put it mildly, nonsense.
"Connect the meter to the network should be not less than 9 volts." - What is the "network" where?
"Directional arrow shows the multimer 0.25 volts" - What is the "arrow" in the digital instrument?
"In case of breakage mechanism lamp will illuminate exactly or does not light up" - What a light, what mechanism?
Just to have something to write. Diodes burn the least. First, we need to look explosive fuse. Then the capacity, and the presence of swellings and leaked oil. Following, a magnetron for continuity. If the diode is in short, the fuse will burn explosives. If the interruption when the oven is much buzz. And we should not forget that in the BB capacitor may remain excessive voltage. Kill not kill, but will shake strongly.
