The WPW10434452 is the genuine OEM dual-element infinite switch for select Whirlpool, KitchenAid, Maytag, Amana, Kenmore, Roper, and Jenn-Air electric ranges. This switch controls power output to dual-circuit surface burners, allowing selection between inner coil only (small burner), both coils (large burner), and infinite variable heat from LOW to HIGH. It directly replaces W10434452, 3148951, and other superseded part numbers.

The WPW10434452 infinite switch mounts behind the range control panel with its shaft extending through to the control knob. Its precision bimetallic contact mechanism cycles power on and off to maintain your selected heat level — from a gentle simmer at LOW to a full rolling boil at HIGH. When this switch fails, your burner loses the ability to regulate temperature accurately, leaving you with a burner that won't heat, won't shut off, or heats at the wrong level.

✓ Common Symptoms Fixed

Burner not heating at any setting. Burner stuck on HIGH and won't cycle off. Burner heating at wrong temperature — too hot or too cold. Intermittent or erratic heating. Burner not responding to knob adjustment. Dual element not switching between small and large burner modes. Burning smell or sparking from behind the control panel.

✓ Installation Tips

CRITICAL: Disconnect power at the circuit breaker before beginning — electric ranges operate on 240V AC. Remove the control panel or rear access panel to reach the switch. Photograph all wire terminal positions before disconnecting. Disconnect all terminals from the old switch and remove the mounting screws. Install the new WPW10434452, reconnect all terminals to their correct positions, and reassemble the panel. Restore power and test all heat settings including both small and large burner modes to confirm proper operation.
