Help wanted on electrolux induction range EW30IS65JSA

[jplloyd]

Oh great wise ones, 

I'm looking for some help on my electrolux induction range (7 year old model EW30IS65JSA ).  A few days ago the burners stopped working with error code E35/E75 AC input voltage too low (first one, then the other), so I followed the service manual instructions and replaced the filter circuit board(p/n 318347000), which had an obvious failure on the board.  Unfortunately (and $600 later) that board went pop when I installed it and tried it out. 
 

I now realize that the original issue with the filter board was that hard-wired fuse on the board had blown, so probably should have expected that was what would happen.  So now I figure I need to replace at least the generator circuit board (318347102), possibly more.  New ones seem to be expensive and/or not in stock, but I can get a used generator board on ebay for $175, or even a whole assembly of the induction boards with two generator boards and filter board new in box for $500.

Currently, it shows E31 (Internal generator error, sync Induction Housing Assembly / Left side cooking zones. ), although it was the right side unit that I powered up when the filter board went pop.

Any advice welcome.  The main thing I am wondering is whether I should replace any burner units, or whether the problem is likely to be contained just to the generator boards, and whether I should replace both generator boards, or try and get away with just one?

Best,

James
