Burner flame does not change when turning the knob — D-shaped shaft hole is worn out or stripped, preventing engagement with the valve stem.
Knob cannot be set to a specific heat level (Lo/Hi/LITE) due to cracked or broken internal mount — burner stays on one setting or won't light.
Knob is seized, stiff, or locked in position due to grease buildup fusing the damaged plastic to the shaft, requiring full knob replacement.
Stainless-look coating has bubbled, peeled, or flaked off — often caused by soaking or harsh cleaning agents — making heat markings unreadable and unsafe.
Knob rocks or pulls off too easily because the D-hole has enlarged from repeated use, no longer gripping the valve shaft securely.
💡 Pro Tip: Is Your Knob the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Knob spins freely without changing the burner flame level
⚠️ Burner flame stays the same from Lo to Hi — knob stripped from shaft
⚠️ Visible cracks, chips, or the stainless coating has peeled off
⚠️ Knob feels loose, wobbly, or does not click into the OFF position
🛠 Diagnosis tip: With gas OFF, remove the knob and inspect the D-shaped shaft. If the plastic D-hole is rounded out or cracked, the knob is definitely the cause. Measure your shaft: it should be 0.22" × 0.25". Always turn gas supply off before servicing any range control knob.
