- Oven or burner knob will not move, rotate, or turn
- Can the oven or burner control knob or burner valve stem be lubricated to prevent sticking?
- Burner knob or oven knob is loose
- Burner knob or valve stem spins freely on Gas Cooktop, Rangetop, Range, or Dual Fuel
- Control knob or stem is stuck
- Burner does not turn on
- Knob insert left on valve stem
Steps to Verify Issue:
- Make sure correct knobs were ordered and received.
- GR Gas Range and Dual Fuel Range Oven Control knobs look very similar but are different and are not interchangeable.
- The knobs for the surface burners are interchangeable.
- See also, Dual Fuel and GR Gas Range Knob Compatibility.
- Verify the knob installation is correct.
- Knobs may fit in more than one location. For example, a burner knob may fit where the oven knob should be.
- Extra knobs come with the Dual Fuel Range.
- Knobs slip onto the burner shaft. To remove, pull the knob out. To reinsert, push the knob onto the shaft.
- If the burner shaft is bent, contact Factory Certified Service for repair.
- It is normal for the Griddle Knob to Be Slightly Looser than the burner knobs.
- Dual Fuel Range and GR Gas Range surface burner knobs have a black metal insert.
- When removing the knob, the insert may stay on the valve stem shaft, causing the new knob to sit out too far and be loose.
- Remove the black insert from the valve stem if needed.
- Inspect the burner control knob for chips or cracks and replace the knob if broken.
- Make sure the knob is being pressed down for cooktops or pressed in for ranges and Dual Fuel before attempting to rotate the knob.
- Turn the knob on and off several times to work valve grease in if the knobs are hard to turn.
- If the surface burner will not shut off, replace the broken knob with one of the other knobs and turn the burner to the off position.
- Lubricant is not recommended for surface burner knobs if stuck on any Wolf appliance.
- Discontinue use of burner until serviced.
