SOURCE: error codes 10 12 16 on kenmore induction cooktop

We purchased a 36" elite model on ebay for our house we are building. I finally installed a year later only to have error codes 39 & 40. I completely dissasembled it and put it back together. No luck. However after much searching I found the service manual for the 36" Icon by Electrolux (same manufacturer as the Elite). The guts look mostly the same. Manual states your codes 10 16 12 are for defective key sensors. I found out that on my cooktop if I held a key for maybe 20 sec or more it would beep once - indicating the key was not defective.

SOURCE: Kenmore Elite Induction Cooktop Error Code 41

I realize this is over a year old. I have the same unit with the same error code. Last night, mine made a popping noise followed by smoke and then displayed the 41 and all E's. I pulled the breaker immediately. I'm sure that at least one controller board is toast.
I called Sears and it is under warranty but for parts only, so I guess I will give them a call and schedule the repairman. This should be fun.

Anyone else experienced this failure??
