This replacement timer knob restores manual timer control on compatible Whirlpool appliances, giving a secure grip and smooth turning for accurate time or cycle selection. Easy-to-replace part for worn, broken, or stripped knobs. What it does:

  • Replaces a cracked, worn, or missing timer knob so you can set and adjust time or cycle settings.
  • Fits onto the appliance timer shaft to provide a secure, easy-to-turn control surface.
  • Helps when the knob spins freely, won't engage the timer, or is difficult to turn.
  • Restores tactile feedback for precise timer/cycle selection.
What's included: Includes: 1 timer knob. Install notes:
  • Disconnect power to the appliance before beginning any service.
  • Most installations require no tools; pull old knob straight off the shaft and push the new knob on until it seats.
  • Align splines on the knob with the timer shaft—do not force; forcing can damage the timer shaft.

Questions & Answers

For Whirlpool Knob, Timer (Control Knob), Single (Part Number: OEM18017358)

1 Answer

Joe, If your timer looks like this WP21001522 then, you do have a retractable locking shaft in the back side of the timer." Remove the timer knob as follows: Locate the hole with the timer knob shaft at the rear center of the timer. Using a small,flat blade screwdriver, pry the rod located in this hole up to release the timer knob. The knob and skirt will then pull straight off." If you have a "metal bodied" timer like this WP21001341 then you will need to unscrew(turn counterclockwise) the knob from the threaded timer shaft. Thanks and Good Luck
