A replacement control knob that restores safe, reliable selection of settings on the appliance. Fits the original shaft design to provide a secure, easy-turn interface for temperature and function selection. What it does:

• Replaces cracked, stripped, missing, or loose control knobs so settings can be selected and held securely.
• Engages the control shaft spline to transmit user input to the selector or valve.
• Provides a tactile grip and clear pointer for accurate setting selection.
• Helps resolve symptoms like a knob that won't turn, won't stay set, or spins freely without engaging the control.

• Disconnect power to the appliance before starting any repair.
• Align the knob to the control shaft spline and push straight on until fully seated; do not force.
• If the knob does not seat easily, verify shaft and spline condition before proceeding.
