No recalls that I know of.  The switch for that burner has shorted and will need to be replaced.  It will be fine once it is repaired.

It sounds like the burner needs to be replaced. When they burn out sometimes they short out to ground. The cooktop will have to be removed from the counter and the glass top opened. You will probably be able to see where the element is burned out. Replace it and you should be fine. If it is too expensive to fix just disconnect the wires to the burner where they attach to the control . Then you can use the remaining burners. I really don't know what a replacement burner costs. An open coil is around $30.

The cooktop will need to be removed from the counter. Turn it upside down and remove the screws. The biggest problem will be removing the cooktop from the counter. Sometimes it is not worth fixing as the part could cost around $400. NEVER use a cracked top as it could suddenly explode. This is tempered glass and very unstable if cracked or chipped.

If you can hear the clicking sound but are not getting a spark then there is probably a short in the ignition system. Check for any loose wires on the ignition system. Make sure all the wires are properly seated. Make sure the spark module is properly grounded. As far as testing the spark module it should be generating a spark of course. The problem is that the average voltage for the spark module is 15,000 VDC so actual testing of that voltage can be difficult. Is the spark erratic?(should spark evenly). An erratic spark timing is a sign of a bad spark module. Is the spark slow? Check the polarity of the electrical plug. If it is clicking evenly then it is probably arcing somewhere inside the cooktop and you just need to find out where. Also be aware that if you get water into the cooktop that can cause possible grounding of the spark module or ignition system.
