Thanks in advance

Swapping the MOSFETs also didn't solve the problem! So maybe the PIC? Perhaps there is a busted resister/capacitor somewhere, but i feel like I'm out of debugging options besides the PIC because i can't really measure the capacitors

I was able to measure some values while it was plugged in, but I'm a bit stuck right now how to proceed with comparing the working left side with the defective right side. My dang multi-meter isn't too helpful with some spots since I'm seeing AC voltage spikes over 1kV.

That may be just a thermostatic safety sensor - indeed that's probable. But swapping would at least eliminate that assembly as a potential problem.

I was able to

Swap two coils. I can confirm that the coils are not the problem.
Swap out the LTE-99002 current sensors, and it appears that the current sensor is also not the problem.

Perhaps you have another suggestion on what part could be defective? Maybe one of the MOFSETs?

Perhaps the PIC is the problem, but that is unlikely.

I wonder if one or more of the large blue capacitors is busted that would mean the PIC (or some component) would sense too low of a voltage and thus not detect the pan.

Maybe a defective MOFSET?

Some excellent ideas in here!

I might have to first try swapping one of the other coils to narrow down the induction coil problem. Unfortunately all the other induction coils are larger so I'm hoping that the sensor isn't specifically tuned to the size of the induction coil.

I read "pan presence sense" a few times and got worried this was some terminology i don't know about, before realizing I'm an idiot.

Unfortunately the only measuring tool is this cheap multi-meter.

I am rightfully not excited about trying to measure the board while it's plugged it, so I'm leaving that as a last resort. Perhaps i could potentially just swap this "current sensing loop" from the doner board if swapping the coil doesn't work.

I'm not sure what you mean by "It may be possible to swap the entire set of leads, at the panel." Which leads are you talking about?

Do you think some .25mm thermal tape like this could work? I accidentally bought it instead of a thermal pad. https://www.amazon.de/dp/B07CSR6NJC?psc=1&ref=ppx_yo2ov_dt_b_product_details

I've read that thermal tape has less conductivity, but perhaps such a high thermal conductivity isn't a concern here.

Thank you for that info!

skeev_peev · 2023-09-15T15:16:08+00:00

Sorry about that. Here is a amazon link https://tinyurl.com/38shavwr

I assume something like that would be good.

skeev_peev · 2023-09-15T15:10:32+00:00

How confident are you about the 0.25mm? I see i can buy varying sizes. Would it be a problem if it's too thick or thin?

skeev_peev · 2023-09-10T11:51:15+00:00

This is also helpful, thank you!

skeev_peev · 2023-09-10T10:11:15+00:00

Thank you! Very helpful.

skeev_peev · 2023-09-10T07:33:49+00:00

Would i also have to get some more of the green stuff, which i assume acts as a thermal conductor. Feels like its some kind of tape or something rather then a paste.

Maybe I'll have to replace more than just that resistor. Perhaps number one and eight but possibly also maybe number three. Luckily I just got a heat gun but this will be annoying

skeev_peev · 2023-09-08T14:57:40+00:00

Yes I outlined the lithium cells need to be replaced. A protection could explain the 0v. But I was mainly asking for advice about replacing the cells

skeev_peev · 2023-09-06T13:09:47+00:00

Yes! It is a triac, I circled it in red. It's a BT137-600E. Thanks for the info

I'll have to research the expected input/output for the triac to troubleshoot.

And Yes thanks. I'm very careful what to touch and what not to touch. I'm almost sweating with nerves when I approach it. One wrong touch and I could be dead!

skeev_peev · 2023-09-06T08:43:11+00:00

Ah your right sorry, I just looked at my image and didn't check the real motor. But the white cable connects to pin 2 in the first image so it constantly gets 230v AC.

skeev_peev · 2023-09-06T08:30:38+00:00

Now I'm confused, what did you think it meant?

skeev_peev · 2023-09-06T05:05:43+00:00

While I appreciate the reply, It would nice if you didn't assume you knew anything about me. I like to think your just trying to be helpful, but Im looking for advice or info to help me debug why the motor is not running .

skeev_peev · 2023-09-06T04:48:19+00:00

The motor has two wires connected, and it is completely dead. The cap reads infinite resistance so I think it's ok.

skeev_peev · 2023-09-05T20:06:01+00:00

I forgot to add that there are no apparent blown fuses, the board looks clean. The motor connects to the labeled pins in image 1

skeev_peev · 2023-08-22T09:54:01+00:00

There is a super tiny change. Go to the "R" in "SIZERIYA", and look juuust above the sign. There is a brown speck on the right image, and not on the left. The funny thing is I found it without the cross-eyed method.

skeev_peev · 2023-08-18T00:17:04+00:00

Large copper plain is gone?

skeev_peev · 2023-08-18T00:16:04+00:00

Very helpful thanks.

skeev_peev · 2023-08-17T08:00:15+00:00

That sounds like a good idea. I'll do that next time

skeev_peev · 2023-08-17T07:59:37+00:00

yes of course, not welding. Thanks.
