The plastic knob has cracked, chipped, or snapped off, making it impossible to turn the burner on or off safely.
The D-shaped inner socket is worn or stripped, causing the knob to spin without engaging the burner valve shaft.
A damaged knob prevents proper engagement with the burner control valve, making it impossible to start or stop the burner.
A broken or slipping knob prevents rotating the valve between LOW and HIGH positions, losing precise heat control.
💡 Pro Tip: Is Your Burner Knob the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Knob spins freely without engaging the burner valve shaft
⚠️ Knob is cracked, chipped, or has broken off from the shaft
⚠️ Cannot turn the burner on or off — knob feels stuck or stripped
⚠️ Heat level will not adjust correctly between LOW and HIGH settings
🔍 Quick Check: Pull the knob straight off and inspect the D-shaped hole inside. If the flat edge is worn round or plastic is broken, the knob needs replacement. If the metal shaft itself is damaged, you may also need part PS235440 (burner control valve). Sold individually — order quantity 4 if replacing all burners.
