Have been regularly using the above cooktop for 6 years without a single issue. After being away from home for 4 months, we tried to turn the cooktop on but it was completely unresponsive. No lights, beeps, error codes, etc. Just...nothing. The circuit in the breaker box is fine, and I tested the wires in the junction box and they are all hot. The glass is spotlessly clean and looks brand new. I turned the breaker off over night, but when turned on in the a.m. no change.

I know there are several control boards inside this model...does anyone have any idea which one might be the culprit? Any other troubleshooting I can do? Thanks
