Whirlpool Surface Burner Control Switch (WP3149400)

The Whirlpool Surface Burner Control Switch controls power to a surface burner and adjusts heat output as you turn the knob. It routes electricity to the burner at the setting you choose so the element can heat, cycle, and maintain temperature. This switch can fail from normal wear, heat exposure behind the control panel, electrical arcing at the contacts, moisture intrusion, or loose/burned wiring connections. Over time, internal contacts can pit or stick, which can cause the burner to stop responding to knob changes or behave unpredictably. These symptoms can help you decide if this switch matches your issue: Surface burner will not heat even though other burners work. Surface burner stays on high and does not respond to temperature changes. Surface burner turns on only at certain knob positions or cuts in and out. Burner will not turn off, or heat continues after the knob is set to off. Control knob feels loose, binds, or does not click/stop as it should. Sparking, burning smell, or heat damage noticed behind the knob area. Intermittent heating that returns when the knob is wiggled or pressed.
