Customer Questions and Answers for Control Knob, 1 Piece by Whirlpool

This control knob attaches to a control shaft so you can select settings on your appliance. Replace a cracked, stripped, or missing knob to restore smooth, accurate operation and a clean factory appearance. What it does:

• Fits onto the control shaft to turn the underlying switch, timer, or valve
• Provides an easy-to-grip interface and clear pointer for setting selection
• Restores proper engagement when the original knob is worn or damaged
• Common symptoms: knob spins freely, falls off, feels loose/wobbly, won't turn the control, broken pointer or insert

• Disconnect power to the appliance; if servicing a gas unit, also shut off the gas supply
• Pull the old knob straight off the shaft—avoid prying against the control panel
• Align the new knob with the shaft orientation (flat/D shape) and press firmly until fully seated
• Proper engagement and pointer alignment before use
