Repairing partially working induction hub

Repairing partially working induction hub

I’m trying to repair an induction cooktop where 1 of the 4 induction coils stopped working while the other 3 still work fine.

What I tested so far:

  • Swapped induction coils between working/non-working zones
  • Confirmed the coils themselves are good
  • Measured the IGBTs with a multimeter and they seem consistent with the working side
  • Found a cracked capacitor

The same board still works for the upper coil so I'm hoping that replacing the cracked capacitor will fix the non working section.

I can easily find the full board, but sourcing the right capacitor seems more challenging.
Any tips on which different capacitor I could use that might be easier to source?

Can I get this done as a Newbie?

I’m trying to repair an induction cooktop where 1 of the 4 induction coils stopped working while the other 3 still work fine.

I thought replacing it would be quite straightforward… then I spent almost an entire day fighting the PCB.

I'm working with this bad boy: https://www.amazon.fr/dp/B09TVL186R

What I tested so far:

  • Swapped induction coils between working/non-working zones
  • Confirmed the coils themselves are good
  • Measured the IGBTs with a multimeter and they seem consistent with the working side

The cracked capacitor is marked:
Z110267339 P10
U12 J 900 C6

Having trouble to find a replacement piece for it online.

Started with a flat tip and later switch to a more beefy tip with helped but I'm still not able to get the solder that's in the board to melt, the fresh solder melt easily but it's like the board solder and the new solder are repelling each other.

Ended up getting the piece out by braking it's legs, but the PCB is still there, even with better access to place the tip I can't seem to get it done.

Any recommended techniques for a induction cooktop PCBs?
