Customer Questions and Answers for Range Terminal Block by Whirlpool

Daniel, No the terminal block would not be the issue, since the other elements work. Since you have radiant elements, you most likely have a damaged wire under the cooktop glass, or possibly the rear burner switches WPW10244639 right rear and/or W10861720 left rear switch, may be damaged. You'll need to lift the cooktop out of the counter, remove the glass cooktop and frame to investigate.
