Whirlpool Stove Burner Switch (WP3149404)

The Whirlpool Stove Burner Switch controls power to a surface burner by routing electricity to the heating element and adjusting heat level as you turn the knob. It also supports the burner indicator light circuit on many ranges so the cooktop can signal when a burner is on. This switch can fail from heat exposure, arcing at internal contacts, or wear from frequent knob rotation. Loose terminals, burned connectors, or melted housings can also cause poor electrical contact, which leads to intermittent operation or heat that will not regulate. If your burner is not behaving as expected, these symptoms can help you decide whether this switch is the cause: Surface burner will not heat at any setting Surface burner heats only on high, or heat level will not change Burner cycles erratically or cuts in and out while cooking Knob turns but does not engage heat, or feels loose compared to other knobs Sparking, buzzing, or a burning smell from the control area during use Burner indicator light stays on all the time, or will not turn on when the burner is on Visible scorching, melted plastic, or discolored terminals on the switch
