If I reset the breaker the control surface for that burner will go on but the element wont heat up and 30 seconds later it will all kick off

Hello and thankyou for using this service!

I am sorry to hear about the problem you are having with your cooktop

Let's work together to find out what is wrong :)

You need to take the top glass off and access the connections to the burner and check for voltage to it. If you are getting voltage then the burner is bad, if you get voltage momentarily and then it goes off, you need to replace the computer board. Of you get no voltage, you need to replace the computer board.

To remove the glass top, pull the cooktop out of the counter and remove the screws around the perimeter bad and the glass will lift off and give you access to test the components.

I have removed the glass top. The problem is that the touch screen control for that burner when pressed wont light up so it wont even go on which means there is no voltage there. The control for that burner will only work if the breaker is reset.

I would say you have a problem with the control board. It would make sense with the fact that it reactes when you reset it.

I would still check to see if you have voltage to the element as that would cause it to time out if it did not get hot. You should be able to just follow the heater ribbons on the burner to there respective connectors on the outside of the heater housing and then use your voltmeter to see if you are getting 220v to the terminals. If you do, then replace the burner. otherwise replace the control board.

The control appears wrong on the picture but if yous earch on the part number, it comes up on other sites.
