Knob spins freely, wobbles, or has completely pulled off the valve stem due to a cracked or worn internal D-shaft adapter.
Burner flame does not respond when the knob is turned between Low and High settings, indicating the knob can no longer engage the valve stem.
Knob is stiff, jams between positions, or accidentally changes settings due to damaged internal spring clip or worn contact surfaces.
Temperature and position markings (OFF, LO, HI) have faded or peeled away, making it impossible to confirm burner setting visually.
💡 Pro Tip: Is Your Burner Knob the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Knob is loose, wobbly, or has detached from the valve stem entirely
⚠️ Knob is difficult to rotate or slips past settings unexpectedly
⚠️ Burner flame does not change when turning knob from Low to High
⚠️ Printed temperature markings are faded, cracked, or unreadable
🛠 Quick Diagnosis: Turn the knob slowly from OFF to HI. If you feel no resistance or hear no click at the ignition position, the internal plastic D-shaft adapter is likely cracked. Because the stem is only available as part of the full knob assembly (WB03K10265), a full knob replacement is the correct and only repair path.
