W10917724 Whirlpool Range Surface Element Switch – The direct fix for a Whirlpool electric range burner that won't heat at all, won't adjust temperature (stays on high regardless of knob position), only works on certain settings, has inconsistent or erratic heat, cycles on and off irregularly, or has a control knob that turns but the burner doesn't respond. The surface element switch — also called an infinite switch — is the variable heat control behind each burner knob that regulates power to the surface element. It provides continuously variable heat from Low to High by rapidly cycling 240V power to the element on and off in timed intervals. When the switch fails, it can no longer regulate power properly. Common failures include: internal contact burnout (element gets no power — burner completely dead), stuck contacts (element stays on high regardless of knob position — can't turn down), erratic cycling (element heats inconsistently — temperature swings wildly), and partial failure (element works on some settings but not others). If you've confirmed the surface element itself is good (swap test with a working same-size element) and the burner still won't heat or adjust properly, the infinite switch has failed. Built with high-quality materials for reliable, long-lasting operation. This genuine OEM Whirlpool part directly replaces W10437094. Easy to install — designed for quick repairs without professional help. Fits Whirlpool, KitchenAid, Maytag, Amana, Jenn-Air, Roper, and Kenmore electric ranges and cooktops. 15–30 minute DIY repair.
