The WS01L15700 is a genuine OEM 5.5-inch radiant surface element used in GE-family smooth-top (glass-ceramic) electric ranges. This element is a coiled resistance heater mounted in an insulated metal carrier; when energized on 240V it heats the glass cooktop above it and transfers heat to cookware. The 5.5" size is typically used for small “single” burners or warming/low-output positions (exact wattage varies by platform; confirm by model). Common failures include an open heating coil, hot spots from coil fatigue, warped carrier causing poor contact to the cooktop, or heat-damaged terminals from loose connections. Symptoms: burner won’t heat, heats intermittently, heats unevenly, trips breaker, or visible scorching/warping under the glass. IMPORTANT: Match by part number and burner position/size. CRITICAL: Turn off the double-pole breaker (240V) before servicing.
