Is This the Right Part?

Common Symptoms

• Knob spins without changing the burner setting
• Burner cannot be turned on or adjusted because the knob is stripped or broken
• Knob markings are worn or illegible
• Knob is cracked or physically damaged

Check Before Replacing

• With power disconnected and the range cool, inspect the knob for cracks, missing pieces, or a stripped internal socket.
• Pull the knob straight off and compare its internal socket with the control shaft; this part is documented for a D-shaped shaft.
• If the knob is intact but the shaft does not respond normally, the underlying control may require separate diagnosis.
