I have not open up the surface element glass yet to check the power control board and main board. I’ve only just found out that there are control boards under the glass top.

My question is which board would most likely be the culprit for all the burners to stop working? Each replacement boards are around $300 each and I replacing each individual board would be an expensive trial and error fix.

Any advice would be greatly appreciated.

This could depend on what response occurs on the interface when a switch is operated. If an LED illuminates to indicate a switch has been engaged, the cooktop main control would be the likely cause of failure. DE92-03657A Range Main Pcb Assembly | Genuine Samsung OEM In Stock
