Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Knob spins without reliably turning the control shaft.
• Knob is loose, wobbly, cracked, or missing.
• Cycle or timer markings no longer align with the selected position.
• The appliance control cannot be set because the knob no longer grips the D-shaped shaft.

Check Before Replacing

• Disconnect appliance power before inspecting or removing the knob.
• Visually inspect the knob for cracks, missing sections, or a damaged internal D-shaped opening.
• With power disconnected, gently compare the knob’s internal opening with the control shaft; it should engage the shaft without excessive looseness.
• After reinstalling, verify that the knob seats fully and that its pointer aligns with the control-panel markings. Do not force the knob or rotate the shaft beyond its normal range.
