Part Number: OEM18042393
Manufacturer Part Number: WP9762441

A rotary selector switch that accepts the control knob and routes user selections to the appliance control circuitry, restoring reliable selection of functions and settings when the original selector fails or becomes intermittent. What it does:

  • Routes electrical signals from the control knob to the appliance control board so selected functions or settings engage properly.
  • Common symptoms indicating replacement: knob won't turn or stays between positions, settings do not change, or selector works intermittently.
  • Replaces a worn, damaged, or non-responsive selector to restore consistent user control.
  • Designed for panel-mounted installation where the knob mates to the switch shaft.
What's included: One rotary selector switch. Install notes:
  • Disconnect power (unplug or shut off circuit breaker) before attempting any service.
  • Access typically requires removing the control panel or console; keep screws and fasteners organized.
  • Match the switch orientation and connector pattern to the removed part; do not force connectors.
  • After installation, restore power and test all selector positions for correct function before reassembling fully.

Looking at the wiring diagram below the LF (infinite switch) drawing, you'll see a rectangular box made up of dashes, inside the drawing it will have the numbers and letters 1,2,3 and A, B and the wire color to attach to the terminals. This is how the L2 power to the element(s) is controlled for the accusimmer circuit.
