EvertechPRO Infinite Surface Element Switch – Compatible with WP9759474 This EvertechPRO aftermarket infinite switch is designed for electric ranges that originally use WP9759474 / 9759474. The infinite switch regulates power to the surface heating element, allowing precise temperature adjustment during cooking. A failing infinite switch may cause a burner to stay on high heat, not heat at all, or cycle inconsistently. This replacement switch is engineered to restore proper surface burner control, helping improve cooking accuracy and safety. Compatible with select electric range models from Whirlpool family brands including Whirlpool, Maytag, KitchenAid, Jenn-Air, and Kenmore, this switch is manufactured to meet or exceed OEM performance standards while offering a cost-effective alternative to branded OEM parts.
