Breaker in panel tripped and won't turn back on

You may have a short circuit to ground fault in the electric cook top. Divide and conquer. Unplug the cook top and try to reset the breaker. If the breaker resets, then you have a problem with the electric cook top. If it doesn’t, then the problem is at the electrical panel side. Either problem will require a qualified technician’s assistance. I hope this helps. Good luck.

Unplug the cooktop and anything else that may be on the same circuit. Any items on the same counter top for example. Try to reset the breaker and remember that to reset the breaker, you must first turn it to the off position and then to the on position. Hope this helps
