this rectifier boards suck, in less than 2 years they will fail and 8 times out of 10 the transistor will burn too many components , nothing like the good' old simple wired transformer

if my memory serves me right, from the two terminals to the body there should no reading on the resistance function, as between the two terminals the reading should be a near short circuit, if not the magnetron is surely defective.

Most times there is more than the IGBT that will blow, you need to look for the other parts that drives the IGBT, cause it most likely takes along other parts around when it blows, or, some of those driving parts will cause the IGBT to blow... Other important parts to check, the HV trancformer, look for possibly burned windings, other coils, capacitors, diodes, etc...

Bonjour. Regarding the high-voltage rectifiers... From what I have read and seen, a regular multimeter won't be able to test these, because the forward voltage when conducting is several volts, not just 0.6 to 0.7V for standard silicon diodes. I have used a 12V power supply and a 1K resistor in series with the diode. Measure the voltage across the rectifier. Hooked up in reverse, the voltage across the rectifier will be the 12V of the power supply. When connected in the forward direction, the voltage across the rectifier will be anywhere from about 5V up to maybe 10V, depending on the device. Today, I was working on a Panasonic microwave (model NN-ST661B) with this exact same inverter module. One rectifier (D702?) was dead short, and the other (D701?) was okay. The inverter wasn't generating high voltage, so the microwave shut down after 23 seconds, just as it is supposed to for this failure mode. A replacement inverter is about $160 CAD.
@pierresgarage26873 ай бұрын
It's possible to take a chance to find a supply for replacement diodes, ( Digi-Key, Mouser, etc) I don't have on hand the number or reference of that diode since There isn't a microwave open close by. One possible way to avoid paying 160$ would be to get a used microwave that works, even if the outside apearance isn't great, all you need is the board, by checking the model number and refering to the proper service manual you'll know if the board is compatible. Note that many models of inverter series within the same power range share the same board... I hope you solve your problem... 🙂

And it does give the Panasonic part number of the inverter board. But, what I'm not sure about is, which other inverter modules could be used to replace the one I have. If you go to eBay, and search for Panasonic microwave inverters, there are quite a few available, both new and used, often with slightly different model/part numbers. They all appear to have the same form-factor, same mounting, same connectors at the same locations labeled the same way. Maybe all earlier or later versions of some kind of "inverter family"? Intuitively, it would seem that any of these could be installed and would probably work. Do all of these inverters put out the same high-voltage DC, controlled by that 3-pin cable from the display panel? Anyway, it's academic now... The owner of the microwave (not me) decided enough time had been spent in this repair, and they will buy a replacement oven. I scrapped the oven, but salvaged the useful bits (panel, turntable, fan, switches, etc.)

Most likely that that either the high voltage board and/or the magnetron are defectives, look in the description for the links to the service manuals, if you're familiar with electronics there is a section on what measures to take in order o test the magnetron and some of the components on the high voltage board. Though, mostly if you're not familiar with high voltage units be very careful not to get injured...

As one side moves, doesn't it cancel out the other side? Result, no change in outcome speed. I'm missing something.
@pierresgarage26874 ай бұрын
As one gets smaller the other wheel gets bigger, then, the ratio is is lets say 2 to 1 in one direction, as it shifts to the other side the ratio will be 2 to 1 in the other direction. this setup allows the change without the need to change the length of the belts cause the variable pulleys travel along the slide bars. You need to figure that the pulleys on the motor and the other one on the driven tool are constant in size. the ratio is directly proportional to the diameter of the drive pulley over the driven one.

@pierresgarage26876 ай бұрын
It's always safer to discharge those capscitors, the best way to procede is to get an appropriate resistor and a wire with aligator clips, you clip one end with the resistor to ground or one lead of the capacitor and with the other end you touch the other end. Avoid touching with both hands or making a part with 2 opposite body parts.....

@pierresgarage26876 ай бұрын
As I remember they are quite easy to reach, if an aligator clip doesn't do it you can use meeter probes with a needle point to get the same result, after discharge use the meter to check for residual voltage, though, be careful with the kilovolts rated parts not to overload you meter's capacity. If you're not rxperienced with electric circuits and electronics, be really careful not to cause yourself injuries...

I have the exact same jack and it won't hold a lift and also leaks oil. I only use it for lifting lighter weight things like lighter parts of a vehicle like a wheel when replacing control arms. Your video is incredibly detailed and concise. Better than a training video. I'm going to try and repair mine as I've had it for so long that I can't bear to part with it. Quick question. Do you remember how much jack oil it took to refill after re-assembly?

I ended up cleaning mine up and it didn't take much oil at all. When re-assembling, if you're having problem lining up the bottle jack part into the main assembly, you can lift up on the saddle and that will change the length of the whole assembly and make lining up a lot easier.
