The WPW10345407 is a genuine OEM Whirlpool range coil surface element designed for Whirlpool, Kenmore, KitchenAid, Roper, Estate, and Inglis electric ranges and cooktops. This critical component provides heat for cooking by converting electrical energy into thermal energy through resistance heating. The coil surface element is essential for range operation—without a functioning element, the burner won't heat, cooking is impossible, and the range cannot be used for stovetop cooking, resulting in complete loss of burner function and inability to prepare meals. The WPW10345407 is a complete coil element assembly that includes the heating coil, pigtail terminal ends, and mounting bracket necessary for installation. The range coil surface element is constructed from premium materials including a nickel-chromium alloy heating coil (Nichrome wire) that provides efficient resistance heating and long service life, high-temperature insulation (magnesium oxide powder packed inside the coil tubing) that provides electrical insulation and thermal conductivity, stainless steel or chrome-plated outer tubing (protects the heating coil and provides structural support), pigtail terminal ends (looped wire terminals that plug into the range receptacle), and a support bracket (provides structural support and maintains proper coil spacing). The WPW10345407 features a 6-inch diameter coil design with 1250-watt power rating, making it suitable for small to medium burners on electric ranges and cooktops. The element operates at 240V AC (standard for electric ranges) and draws approximately 5.2 amps at full power (1250W ÷ 240V = 5.2A). The pigtail terminal design allows for easy plug-in installation without tools—the looped terminal ends simply plug into the range receptacle and the element lifts into place. The coil element is designed to heat evenly across the entire 6-inch diameter, providing consistent cooking performance for pots and pans. The WPW10345407 replaces older coil element part numbers including W10345407, 9761348, 660532, 74003019, AP6019975, PS11752445, EAP11752445, and similar elements and features improved heating coil alloy for better heat distribution and longer lifespan (heats 15% more evenly than previous generation), enhanced insulation for better electrical safety and thermal efficiency, upgraded terminal ends for better electrical contact and corrosion resistance, optimized coil spacing for better heat distribution and cooking performance, improved outer tubing for better durability and resistance to warping, and reinforced construction for better reliability across all compatible range models. The range coil surface element operates through electrical resistance heating: when the burner control is turned on, electrical current flows through the heating coil; the high resistance of the Nichrome wire causes it to heat up; the coil glows red hot (approximately 1200-1500°F / 650-815°C depending on power setting); heat radiates from the coil to the cookware placed on top; the burner control regulates power to maintain the desired temperature; when the control is turned off, current stops and the coil cools. Common failure causes include normal wear from age and repeated heating cycles (typical element lifespan 5-8 years with average use), coil breakage from thermal stress or physical damage (most common failure), terminal corrosion from moisture or spills (causes poor electrical contact), coil warping or sagging from overheating or heavy cookware (reduces heating efficiency), element burnout from electrical overload or short circuit, manufacturing defects, or premature failure from low-quality replacement elements. When the range coil surface element fails, symptoms include burner doesn't heat at all (broken coil or open circuit, most common symptom), burner heats unevenly or has hot spots (coil damage or warping), burner glows in some areas but not others (partial coil breakage), burner sparks or arcs (damaged insulation or short circuit), visible damage to coil or terminals (cracking, breaking, or burning), burning smell from burner area (insulation breakdown), or burner trips circuit breaker (short circuit or electrical overload). The WPW10345407 is a direct replacement coil element that provides reliable, even heating for optimal cooking performance and long service life. IMPORTANT: When the coil element fails, verify the range receptacle is not damaged—damaged receptacles cause poor electrical contact and premature element failure. CRITICAL: Always unplug the range or turn off the circuit breaker before working on coil elements to prevent electrical shock. This repair involves working with 240V electrical components—if uncomfortable with this repair, hire a qualified appliance technician.
