Cafe Induction range CHS900P2M1S1 suddenly stopped working

[Joe_Fire]

My 3 year old cafe´Induction range top stopped working correctly. Using the usual cookware it will heat for about 10 seconds then just shut down. Tried the "precision" cookware too, no joy.  Even pulled the battery from the pan in case that was causing an issue. First acted up lat night while boiling a pot of water fan started running more than usual then shut down. Was able to finish cooking using different burner. But this morning, nada. Tried turning the breaker off for 5-10 minutes,no help. The wifi connection is up.I can see the controls and it shows the percentage of the knob setting then just shuts off. 

So any ideas? I'm aware the control board could be an issue, but it's.....

a.) very expensive and

b.) unavailable

Thanks

wellI managed to find a replacement, i think it was the only one in stock anywhere. Anyone have a link to a disassembly guide  or service manual?
