New Dryer Smells Like Gas? Here’s the 1-Minute Safety Check
The arrival of a new appliance should bring convenience, not concern. Yet, when a new dryer smells like gas, it can immediately trigger alarms. Understanding the difference between a normal initial “burn-off” smell and a genuine gas leak is critical for your safety and peace of mind.
While some odors are a normal part of the manufacturing process, a distinct gas smell always warrants immediate and careful attention. This guide will help you identify the cause of the odor, perform essential safety checks, and know exactly when to call a professional.

First Things First: Is It a Gas Leak?
Natural gas and propane are odorless in their natural state. Utility companies add a chemical called mercaptan to give it a distinct and unpleasant smell, often described as rotten eggs or sulfur. This is your built-in safety warning.
If you detect this specific “rotten egg” smell, you must act immediately. Do not operate any electrical switches, use your phone, or create any sparks. Exit the building, and from a safe distance, call your gas company’s emergency line or 911.
Distinguishing Normal New Smells from Dangerous Gas Odors
New dryers often emit smells during their first few uses. These are typically caused by the heating of residual oils, coatings, and adhesives from the manufacturing process. These “burn-off” odors are normal and temporary.
Unlike the smell of mercaptan, these initial smells are more likely to be described as an oily, chemical, or burning plastic scent. While unpleasant, they do not indicate a gas leak and usually dissipate after running the dryer for a 20-30 minute cycle without clothes. It’s similar to how you might notice a new dryer heating element smell in an electric model, which is also a normal part of the initial operation.
Immediate Action Plan for a Suspected Gas Smell
If the smell is sharp, persistent, and resembles rotten eggs, do not hesitate. Your safety is the absolute priority.
- Do Not Operate Electronics: Do not turn any lights or appliances on or off. A tiny spark from a switch can ignite gas.
- Ventilate: If you can do so quickly and without flicking switches, open doors and windows to air out the area.
- Turn Off the Gas Supply: Your dryer should have a dedicated gas shut-off valve on the supply line behind it. If it’s safe to reach, turn the valve handle so it is perpendicular to the pipe to shut off the gas flow.
- Evacuate Immediately: Get everyone out of the house.
- Call for Help: From a safe location away from the house, call your gas utility’s emergency number or 911. They are equipped to handle these situations safely.
Never assume a gas smell will just go away. It is always better to be cautious and have a professional confirm that there is no leak. A persistent smell of gas could indicate a serious hazard.

Common Causes for a Gas Smell in a New Dryer
Once you’ve ruled out an immediate emergency, you can investigate other potential causes for the odor. Often, the issue is related to the installation or initial operation of the appliance.
1. Normal Manufacturing “Burn-Off”
As mentioned, the most common reason for an unusual smell from a brand-new dryer is the burn-off of manufacturing residues. New parts are often coated in oils or sealants to protect them during shipping.
These substances will vaporize and create a noticeable odor during the first one or two heating cycles. This smell is typically oily or chemical in nature and should not be confused with the distinct sulfur smell of a gas leak. To resolve this, run an empty cycle on high heat for 20-30 minutes with the laundry room well-ventilated.
2. Improper or Incomplete Installation
An improperly installed gas line is a primary cause for concern and a significant safety hazard. A loose fitting or a connection that was not properly sealed can result in a slow, but dangerous, gas leak.
Every gas connection is a potential leak point if not secured correctly. DIY installations without the proper tools or knowledge can easily lead to these issues. It’s crucial that a licensed professional handles gas appliance installations to ensure all connections are tight and leak-free.
3. Issues with the Dryer’s Igniter
A gas dryer uses an igniter to light the gas from the valve. If the igniter is slow to light or is malfunctioning, a small amount of unburnt gas can be released into the drum at the beginning of the cycle. This can cause a brief whiff of gas on the clothes or inside the dryer door.
While a small, brief smell at the start of a cycle can sometimes occur, a persistent smell that lingers indicates the igniter may be failing. This requires professional service to repair or replace the faulty component.
4. Clogged or Incorrect Venting
Proper airflow is critical for a gas dryer’s safe operation. If the exhaust vent is clogged with lint, crushed, or has too many bends, it can lead to poor combustion. This incomplete burning of gas can produce fumes and odors, including carbon monoxide.
Ensure your dryer vent is made of rigid or semi-rigid metal, is as short and straight as possible, and terminates outside. Never use flimsy plastic or foil venting, as these are fire hazards and can easily trap lint.
Decoding Different Dryer Smells
Not all strange smells are the same. Identifying the specific odor can help you diagnose the problem more accurately. Here is a table to help you distinguish between common new dryer smells and their likely causes.
| Smell Description | Potential Cause | Action Required |
|---|---|---|
| Rotten Eggs or Sulfur | Gas Leak (Mercaptan) | Evacuate immediately and call your gas company. |
| Oily or Metallic | Normal “burn-off” of manufacturing oils on new parts. | Run one or two empty high-heat cycles to dissipate. |
| Burning Plastic or Rubber | Protective coatings on new electrical components or belt friction. | Run an empty cycle. If it persists, have a technician inspect the belt and motor. |
| Chemical or “Fishy” Smell | Off-gassing from new sealants, plastics, or adhesives. | Ventilate the room and run a few empty cycles. Should fade over time. |
The Importance of Professional Installation
While it may be tempting to save money with a DIY installation, the risks associated with gas appliances are too high. A professional installer ensures safety and compliance with local codes.
A certified technician will perform a leak test on all gas fittings using a special solution or an electronic gas detector. This step is non-negotiable and provides peace of mind that your appliance is installed safely. Improper installation can not only lead to dangerous gas leaks but may also void your manufacturer’s warranty.
When to Call for Professional Service
You should call a qualified appliance technician or your gas company if:
- You smell the distinct “rotten egg” odor of gas.
- The gas smell persists after the first few cycles.
- You suspect the gas line connection is loose or was improperly installed.
- The dryer operates with a yellow, sooty flame instead of a clean blue one.
- You hear a hissing sound near the gas connection.
Even if you have a specific model, like a GE gas dryer that smells like gas, the safety principles are universal. These symptoms can apply to any brand and signal a potentially serious issue that needs expert attention. Similarly, if you notice a rotten egg smell elsewhere, such as when your garage smells like rotten eggs, it’s crucial to investigate the source immediately, as it could be a gas line issue unrelated to your dryer.
