Arrived at home found breaker for cook top in off position. Performed diagnoses on circuit. Checked ohms on wire for problems everything checked out. Turned breaker on. But had no voltage at cooktop. Turned breaker off and on rapid a couple times breakers contacts made connection. Had power at breaker and cooktop. Cooktop still would not come on. Checked power at cooktop eye had 15 volts being put out. Cooktop is bad or controls are bad. Also recommend replacing breaker due to problems at beginning. While at panel noticed double tapped neutrals and breakers which both are a hazard and safety risk advised customer and left qoutes for needed repairs.
