Possible Causes
Grease buildup around valve stems, Worn valve internals, Damaged knob or shaft, Misaligned control panel
How to Fix / Troubleshooting
Safety first: Turn off gas and power before removing knobs or panels.
- Remove knobs: Pull the control knobs straight off the shafts. Clean the knobs and surrounding panel with mild detergent.
- Inspect valve stems: Check for grease or debris around the stems. Wipe clean with a cloth; do not flood with solvent.
- Lubricate if allowed: Some gas valves can be lubricated internally, but this usually requires disassembly and should be done by a technician using approved high-temperature grease.
- Replace worn valves: If stiffness persists or the valve does not stop correctly at OFF, replace the gas valve for that burner or oven function.
Warning: Incorrect reassembly of gas valves can cause leaks. Gas valve replacement should be performed by a qualified gas technician.
