Best Seller
Manufacturer Part
4.89 (64)
By: Whirlpool
Part Number: OEM18041883
Manufacturer Part Number: WP9756824

This wire harness connects the control/switch assembly to the appliance's thermal cutoff and control circuits, restoring reliable electrical connections for proper operation. It's a direct-fit replacement when the original wiring is damaged or corroded. What it does:

  • Provides the factory routing and connectors between the control/switch and TCB/thermal cutoff
  • Re-establishes lost or intermittent power caused by damaged wiring or broken terminals
  • Helps stop failures that cause controls to be unresponsive or cycles to stop unexpectedly
  • Uses OEM-style terminals and insulation to match original fit and function
What's included:
  • One wire harness (switch TCB) as shown
Install notes:
  • Disconnect power before starting — verify the appliance is completely de-energized
  • Take photos of existing wire routing and connector locations to ensure correct reassembly
  • Plug connectors fully and secure the harness along original clips or tie points; avoid sharp edges
  • If terminals are damaged at mating parts, inspect and replace those components rather than splicing connectors

The triple burner on your unit does not have the same square ignition switch as the other burners and just has a microswitch on it that only comes with the valve part number WP9760519.

The ignition switch would be the most likely cause for the issue.
