Do not use switches, the dryer's controls or anything that can spark while you are inside. Let the utility confirm the house is safe, keep the gas shutoff to the dryer closed, and book the repair only after that. ## What it usually means. Natural gas and propane are odorless, so utilities add a sulfur scent that smells like rotten eggs precisely so a leak cannot go unnoticed. Near a gas dryer that smell has two very different meanings. A brief whiff as the burner lights can come from a slow ignition, while a steady smell, or one present with the dryer off, points to gas escaping at the flexible connector, the shutoff valve or the valve assembly on the burner. Nobody can tell which from the laundry room, which is why the first step is always to leave and let the gas utility check. The 5 causes, cheapest first Answer these first 01 Is the smell there when the dryer is off, or only when it runs? 02 Is it a short puff when the burner lights, or a steady smell that stays? 03 Was the dryer recently moved, installed or pushed back against the wall? 04 Can you hear a hiss behind the dryer, near the gas line? 05 Does the burner click several times before it lights, or not light at all? ## Check these before you book. Dryer smells like gas: 5 checks, and none of them costs anything. 01 If the smell is steady or strong, leave the house now, leaving lights and switches as they are, and call the gas utility from outside. 02 Do not start the dryer, unplug it or flip any switch while the smell is present. 03 Once the utility has cleared the house, note whether the smell came only at ignition or all the time. ### Also worth checking - Check whether the dryer was moved recently and whether the flexible line behind it is kinked. - Keep the gas shutoff behind the dryer closed until a technician has checked the connection. ## The causes, cheapest first. 5 things dryer smells like gas turns out to be, from loose or damaged gas connector to smell from another appliance. [The cost guide](https://dryerrepair.center/cost/) 1. 01 low ### Loose or damaged gas connector The flexible line between the shutoff valve and the dryer can loosen or crack when the dryer is moved. This is the most common source of a steady smell, and the utility or a qualified gas technician should confirm it before anything else. [Fixed by gas burner and igniter repair](https://dryerrepair.center/services/gas-burner-and-igniter-repair/) 2. 02 low to moderate ### Slow ignition from a weak igniter A glow igniter that heats too slowly lets gas flow for a moment before it lights, which releases a brief puff of odor at the start of each heat cycle. [Fixed by gas burner and igniter repair](https://dryerrepair.center/services/gas-burner-and-igniter-repair/) [On a gas dryer](https://dryerrepair.center/types/gas-dryer-repair/) 3. 03 low ### Flame sensor not reading the flame The sensor tells the valve whether the flame is lit. A failing sensor can cause repeated ignition attempts, each with a short whiff of gas. [Fixed by gas burner and igniter repair](https://dryerrepair.center/services/gas-burner-and-igniter-repair/) 4. 04 moderate ### Gas valve coils not closing cleanly The coils on the burner's valve open and close the gas. When they weaken, the valve can behave unpredictably, and the burner may light late or cycle oddly. [Fixed by gas burner and igniter repair](https://dryerrepair.center/services/gas-burner-and-igniter-repair/) 5. 05 varies ### Smell from another appliance A water heater or furnace sharing the room or the gas line can produce the same smell. The utility's check covers the whole line, not only the dryer. [Book a diagnostic visit](https://dryerrepair.center/services/diagnostic-visit/) 6.

Do I still need to leave? If you are unsure how strong it is, treat it as a leak and leave. A brief smell right at ignition is often a slow igniter, but that is a conclusion for after the gas utility has checked, not before. Utilities generally check a reported gas smell without charge. ### Can I tighten the gas connector myself? It is not a good idea. Overtightening can crack an old flare fitting, and the right fix is often a new connector rather than a tighter old one. Close the shutoff valve and leave the connection to the utility or a qualified technician. ### Is it safe to use the dryer on air-only until the repair? Not with the gas valve open. If the utility has cleared the house and you close the dryer's gas shutoff, an air-only cycle does not use gas. Ask the technician before relying on it. ### Do I need a carbon monoxide alarm near a gas dryer? It is a sensible precaution for any home with gas appliances. A gas dryer vents its exhaust outside, and a blocked or disconnected vent is one way combustion gases can enter the house. --- **[Read on the site: Dryer Smells Like Gas: Causes and Fixes | DryerRepair.center](https://dryerrepair.center/problems/dryer-gas-smell/)** **[Book a visit with DryerRepair.center](https://dryerrepair.center/schedule/)**
