What to do
- If the gas smell is strong, leave the house immediately and call your gas utility or 911 from outside; do not use light switches, phones, or anything electrical inside.
- If the smell is faint and only near the dryer, do not operate the dryer.
- If you know the location and it's safe to do so, shut off the gas supply valve to the dryer.
- Do not attempt to inspect, tighten, or repair any gas line fittings yourself.
- Ventilate the area by opening doors if it's safe to do so without using any switches or the dryer.
- Contact a licensed gas appliance technician or your gas utility to inspect and repair the leak.
- Do not use the dryer again until a professional confirms the gas connections are safe.
