What to Do When You Suspect a Dryer Gas Leak

A gas leak in your dryer can be a serious safety concern that needs immediate attention. Gas leaks pose health risks and fire hazards. If you suspect a dryer gas leak, follow these essential steps to address the issue safely, and know when to reach out to Vancouver Appliance Service Pros for expert assistance.

1. Inspect for Supply Line Leaks

One of the primary sources of dryer gas leak could be from the supply line. To check for leaks:

• Turn on the gas valve and allow the room to sit undisturbed for 15 minutes.
• Use a fan to blow fresh air into the area for 5 minutes.
• Apply soapy water or a leak detection fluid generously to all fittings on the gas supply line, starting from the gas shutoff valve and moving toward the dryer. Look for bubbles, which indicate a leak.

If bubbles form, you’ve identified a leak. Shut off the gas, repair the leak, and recheck to ensure the problem is resolved.

2. Check for Gas Valve and Internal Component Leaks

Gas valve leaks or issues with internal components can lead to gas smells. Here’s what you should do:

• Inspect the gas valve and associated fittings for any loose connections. Tighten any loose fittings to ensure a secure seal.
• Look at the gas valve solenoids and control board relays, as malfunctioning components can cause dryer gas leaks. Solenoids may become weak or damaged, and relays may stick, preventing the gas valve from functioning correctly.

If you suspect internal components are causing the problem, it’s advisable to consult a professional to address these technical issues.

3. Address Ignition Problems

Faulty ignition components can also lead to gas leaks. Follow these steps to diagnose and fix ignition issues:

• A weak igniter or flame sensor may not ignite the gas properly, causing it to leak. Check the igniter for signs of wear or damage and replace it if necessary.
• Ensure the burner assembly is clean and free from obstructions. A dirty burner or incorrect air mixture can prevent proper ignition.

Adjust the igniter’s position if needed to ensure it is close enough to the gas-air mixture for proper ignition.

4. Check for Low Fuel Levels

For propane dryers, low fuel levels can affect the ignition process, leading to a gas smell. Here’s what you can do:

• Check the fuel level in your propane tank. If it’s low, refill the tank to ensure the dryer receives an adequate fuel supply.
• Be aware that low fuel levels can affect the performance of other gas appliances in your home, potentially causing a gas smell.

By addressing the fuel level, you can often resolve the issue of gas smell and ensure proper dryer operation.

5. Inspect for Home Gas Piping Leaks

If the smell persists after initial checks, there could be a problem with your home’s gas piping. Here’s how to address it to prevent potential dryer gas leak:

• Locate and shut off the gas valve for your dryer.
• Ventilate the room by blowing fresh air into it for 5 minutes. Run the dryer on a no-heat setting for 10 minutes, followed by a heat setting (with the gas valve still closed) for another 10 minutes to exhaust any residual gas.
• Allow the room to sit undisturbed for 30 minutes. If you still detect a gas smell, there may be a problem with the home’s gas piping, and you should consult a plumber for a professional inspection.

6. Avoid Exhaust Recirculation

Improper airflow can cause a recirculation effect that leads to gas smells. Ensure that:

• The intake air for your dryer is not coming from areas where the exhaust is vented. For example, if a window in the laundry area is open, it could be drawing in exhaust air.
• Close any windows near the dryer and open a window on the opposite side of the home to ensure proper ventilation and separation of intake and exhaust air.

Proper airflow is crucial for preventing gas smells and ensuring the dryer operates efficiently.
