@@PowerOn- Hi Simon I recently revisit my same cooktop (IGBT blown again due to my poor workmanship;). This time I’d found out easier way to reinstall the metal clip. Those clips has tiny lip to engage with the groove on heat sink. Just need to position it properly, and press it in with a vice sandwiching just by the heatsink itself (be careful to leave PCB free without force exerted on it during pressing) Even better if you have a pliers wide enough for the clip width.

Great video. I had exactly the same problem with my GE Profile PHP900DMBB cooktop a couple years ago. The trace on the board was blown. Unfortunately mine didn't have the fuse brackets installed but the board had the mounting points for the fuse brackets (make sure to get the brackets rated for 20amps as the cheap ones are not). The writing on the board even specified a 20A slow blow fuse. That MOSFET clip is probably the hardest part of the job. I'm even impressed that you got it off. In my frustration I cut off all the components on the side of the board figuring that they would be cheap to replace. I was wrong. Each of those MOSFETs was $12. The bridge rectifier in the middle was cheap. I positioned them all with the clips before I soldered them all back into the board and that worked fine. Fortunately I was able to find the exact parts.

Hi Francois. Yes, you've identified one of the harder parts of this repair. The clips are both difficult to remove and replace. Im sure in the factory they must have a specialist tool. I remember removing the clips by sliding them out from the end of the aluminium heat sink. Gently tapping with a hammer and broad/blunt screwdriver was the technique. Not easy but doable. Refitting is the reverse but a bit more difficult as you have to also lever the clip open as you slide it back into position. Good luck!

A "loud bang" sounds like a MOSFET. I always "enjoy" those loud bangs when I work on SMPS power supplies. It's always a good idea to keep the IGBTs or FETs out of circuit and put a scope on the BASE or GATE and read for clocking, then check the COLLECTOR or DRAIN for a short before replacing them. The CURRENT SENSE resistor is often blown along with the FET so the IC that drives the FET won't be able to detect proper function of the FET even if you replace it, and the IC itself can be blown too. P.S. I've handled MANY FETs and have NEVER "zapped" one with ESD. It's not as big of a risk as you might think.
@PowerOn-4 жыл бұрын
Hi Rick, lots of good information here, thanks for your reply. Just a note on static electricity and generally on ESD problems. You're experience of never having zapped a device is common. However, what I understand from my studies and also several years of experience at work is that the damage you can do to a device is not to kill it dead but to damage it so it's life is much reduced. You can in effect create 'walking wounded'. By taking simple precautions at home you can minimise this, but at work where we make devices guaranteed to work for 25 years it's a whole different storey of ESD flooring, desks, tools clothing, shoes and humidity control. Honestly, it does my head in sometimes 🤪

Hi Simon I removed the four IGBT's to test using a simple test procedure, (using diode test on digital meter) between the emitter, collector, and gate. Between two IGBT's that were side by side, I got absolutely nothing E-C, and after touching the gate ....no change. Does this suggest the circuitry was completely open? On the other two IGBT's, I got completely shorted on one for both tests (as if probes are touching), and on the last, I got 0.32 reading across E-C for both checks. Any thoughts? As I previously mentioned, I have looked at this board very closely and see no indications of any component failure. Is the component between the IGBT's a diode bridge? Should this be tested? If so, can it be tested in cct? I am thinking about how difficult it would be to remove the clamp. I am shuddering to think of how difficult it is going to be to replace these clamps.

Would it be safe to assume this identification means zener diode? You mentioned this in your video. As I look for a schematic, it appears Electrolux only provides board information. Would you happen to know how to identify this diode to purchase? There is another diode at the opposite end for the other element circuit. How does one identify what the diode is? I was looking for a way to attach a photo of this failure, but it doesn't appear to be a way to do this. It appears there are quite a few of these diodes on this board. Is there a generic diode used universally in this application?

taxicamel When i found my zener diode not connected I initially looked around for component markings but it seem like most smd's that tgey are too small to mark. My only suggestion is to remove what looks like a good one in (from the same location on another ring) and test its avalanche voltage. Without a scematic with component values it can become an impossible task to troubleshoot appliances. My only other suggestion is to google for similar circuits and see if you can find some options. The circuit should work without the zener as its role is to protect the igbt from high transients. In fact my hob worked for years before this latdnt defect resulted in the igbt failing.

Too long ago for me to remember reliably! I'd geuss it was a standard size, 30mm long. If you have a choice Id use a slow blow type if available.

Very interesting. In which year was built this hob? Does it use the same boards as the current Miele hobs? Which IGBT Transistors were built on? (I have no audio on this PC, if you said it in the video)
@PowerOn-7 жыл бұрын
The original IGBT Transistor is an IXYS TO-247 ( ISOPLUS-247 ) IXGR32N60CD1 Although there are other equivalents you can use. The hob is about 12 years old now and whilst I can't say for certain when I bought it I think the vendor said it was built in a factory that built Miele branded products also
@Tyco0727 жыл бұрын
Thank you. Then these boards are probably of the 1st generation, which had some reliability problems with the IGBTs. But 12 years is a very good duration for an induction hob!! This board is made by the German company EGO. Boards by EGO are mounted on the Miele and AEG/Electrolux hobs. The current boards that I have seen have a different layout and they mount 60Amps IGBTs Toshiba GT60j323. Bosch/Siemens hobs use the.GP4068D. Could they work also on your board?
@PowerOn-7 жыл бұрын
Quite possibly - If I need to make any further changes I'll take a look at the specs. You may have missed the details int he video but I'm pretty sure the IGBT's failed due to a zener diode not begin properly mounted on the board from day 1.
@Tyco0727 жыл бұрын
Thank you. I didn't understand what was happened with the zener. To understand the spoken english is much more difficult for me. Do you know which type is the zener? The present hobs of Miele use EGO boards whith the same layout as these, but I don't know which IGTBs type they use. However these are very good, if they lasted 12 years without failures on the IGBTs.

Sorry I don't know the specification of the zener, its a small smd device with no markings. I made sure it was not short circuited or OC and then simply soldered the one side of the zener that had never been attached properly when the board was 1st made. I assume the zener is in the circuit to clamp any voltage spikes that might damage the igbt's

do you know the value o the zener diode

No. Unfortunately they don't mark zener diodes with their rating. Nor is the silk screen of the PCB marked. Perhaps a better electronic engineer than I can specify a value by reviewing the data sheet for the mosfet!

@PowerOn-4 жыл бұрын
I'm not understanding your question. If you are asking about the voltage specification for the diodes I'd check the existing part number and look up the data sheet. There are usually alternative parts from a few different manufacturers available, you just need to match the key parameters as best you can.
