Customer Questions and Answers for Indicator Light by Whirlpool

John, A "hot surface " light remaining on is usually due to a stuck switch on the element sensor (Terminal 1B to 2B on the sensor should be an "open" circuit, when cool) if it's a closed circuit when cool, the switch is stuck and causing the light to remain on. You will need to raise and remove the glass cooktop, to access the burners and wiring and will need a multi meter TJMA-DMT3 to test the circuit on the sensor. To raise the cooktop, you'll need to remove power to the range, open the oven door and remove the two(2) 1/4 in. hex head screws(one on each end) of the flange, on each corner edge, of the oven opening, and raise the cooktop glass. remove the wires from the two terminals and check for the "open" circuit across the 1B and 2B termianls. Thanks and Good Luck
