Surface element fails to regulate heat correctly. Surface element remains on or cycles abnormally. Check Before Replacing With power disconnected, compare the replacement switch's terminal layout and markings with the original before transferring wires. If the element will not heat, verify that the control knob and switch shaft operate normally and that wiring terminals are secure. Use the appliance's wiring diagram and a qualified electrical test procedure to check switch continuity; do not work on an energized range.
