Whirlpool W11458879 Main Wire Harness Ceramic Cooktop

Product Description

The Whirlpool W11458879 is a main wire harness designed for ceramic cooktop assemblies. This harness routes low-voltage control signals and line-voltage power between the main control board and the surface heating elements. It is an OEM replacement component used by appliance technicians servicing Whirlpool-brand ceramic glass cooktops. The harness is a direct-fit part that restores factory wiring integrity when the original harness is damaged, burned, or shows signs of failed connector pins. Proper installation ensures accurate element cycling, consistent heat output, and safe operation of the cooktop surface.

This wire harness is suited for residential ceramic cooktop applications. The part code structure references a 4-surface, no-probe configuration with a specific connector layout matched to the LCX1 control platform. Appliance service technicians performing component-level cooktop repairs will find this harness applicable to the relevant Whirlpool ceramic cooktop production runs. Consult the model-specific wiring diagram before installation to confirm connector orientation and circuit routing.
