How to Fix / Troubleshooting

Safety first: Immediately shut OFF the generator and close the gas supply valve. Do not operate the unit or create sparks or flames.

  • Ventilate area: Allow gas to dissipate before approaching.
  • Visual inspection only: Look for obvious damage to gas piping, flexible hose, and regulator. Do not tighten fittings while gas is on.
  • Do not use open flame: Never use matches or lighters to check for leaks. A soap-and-water solution can be used by qualified persons once gas is turned back on.

When to call a technician: Any suspected gas leak must be addressed by a licensed gas fitter or generator technician immediately.
