Customer Questions and Answers for Timer Knob Assembly (Single) by Whirlpool

Timer knob assembly restores manual control of the appliance timer so you can select and change cycle times with a secure, easy-to-grip knob. Replaces a cracked, worn, stripped, or missing timer knob to restore normal operation. What it does:

• Mounts to the timer/control shaft to allow manual selection of timed cycles.
• Re-establishes engagement when the original knob is stripped, loose, cracked, or missing.
• Provides a firm grip and tactile feedback for accurate setting of cycle times.

• Disconnect power to the appliance before servicing to reduce risk of shock.
• Pull the old knob straight off the control shaft; align splines and push the replacement knob fully onto the shaft until seated.
• If the knob uses a set screw, tighten gently—do not over-torque.
• If the control shaft is damaged or the knob will not engage properly, replace the control.
