Symptoms

  • Rotten egg or sulfur smell near the dryer
  • Smell noticeable when the dryer starts a cycle
  • Smell lingers even when the dryer is off
  • Hissing sound near gas connections

Likely causes

  • PossibleGas valve or line leakA failing valve, fitting, or connector can leak gas, which is intentionally scented for detection.
  • PossibleIgniter failing to light gas promptly, allowing brief gas buildupA weak igniter can let gas flow briefly before ignition, producing a brief smell during startup.
  • PossibleLoose or improperly connected gas line fittingA connection that wasn't fully tightened during installation or a move can leak slowly.
  • Less commonDamaged flexible gas connectorAn old or kinked gas connector hose can develop a leak point.

What to do

  1. 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.
  2. If the smell is faint and only near the dryer, do not operate the dryer.
  3. If you know the location and it's safe to do so, shut off the gas supply valve to the dryer.
  4. Do not attempt to inspect, tighten, or repair any gas line fittings yourself.
  5. Ventilate the area by opening doors if it's safe to do so without using any switches or the dryer.
  6. Contact a licensed gas appliance technician or your gas utility to inspect and repair the leak.
  7. Do not use the dryer again until a professional confirms the gas connections are safe.

When to call a pro

Always call your gas utility or a licensed gas appliance technician for any gas smell; never attempt to diagnose or repair gas line issues yourself.
