A gas dryer relies on an intricate ignition system to create a flame for drying clothes. At times, you may notice the igniter glowing brightly yet, surprisingly, no flame arises. This can be due to a range of causes.
For instance, brands like Maytag and Kenmore have been reported by some users to showcase this issue when there’s a malfunction in the gas valve solenoids. These solenoids control the gas flow to the burner assembly; if they fail, the igniter might glow without leading to a flame.
In other scenarios, you might experience the igniter not glowing at all. This indicates a completely different set of problems, such as a broken igniter or issues in the electrical pathway.
On the contrary, if the dryer igniter works effectively and still doesn’t produce a flame, the problem could lie in the flame sensor or the burner assembly itself. Regular inspection and timely intervention can help address these concerns, ensuring your dryer remains functional and efficient.
Whether you’re a DIY enthusiast or prefer professional intervention, it’s crucial to diagnose the problem accurately to apply the right solution.
Gas Dryer’s Ignition System
The ignition system in a gas dryer plays a pivotal role in determining how efficiently your clothes dry. This system comprises several components that work in tandem to create a flame. At the heart of the ignition process is the igniter.
Acting like a glow stick, the igniter heats up until it’s white-hot, igniting the gas released by the valve solenoids. The flame sensor then monitors this flame, ensuring that it remains consistent throughout the drying process. If any of these components malfunctions, it can disrupt the entire drying cycle.
Familiarity with this ignition process can be beneficial, especially if troubleshooting is necessary. For optimal performance, periodic maintenance checks on these components can prevent potential drying hitches.
Key Symptoms & Initial Observations
Observing your gas dryer’s behavior can offer clues about underlying issues. Some red flags include clothes taking longer to dry or the dryer running hot without producing results.
If the igniter glows but there’s no accompanying flame, it’s a clear sign that the ignition system is compromised. Such observations can serve as a starting point for targeted troubleshooting, saving time and potentially expensive repair costs.

Common Causes of the Issue and How to Solve Them
Gas dryers are crucial appliances in many households, streamlining the laundry process. Yet, a frequently reported issue is the igniter glowing without producing a flame. To efficiently address this, one must identify the common causes and their respective solutions.
1. Broken Gas Valve Solenoids
Gas valve solenoids are responsible for controlling the flow of gas to the burner assembly. If they malfunction:
Solution:
- Inspect the solenoids for any visible wear or damage.
- Use a multimeter to check for continuity. If they’re defective, replace them to ensure a consistent gas flow.
2. Obstructed Burner Assembly
Over time, the burner assembly can get clogged with lint or other debris, preventing the gas from reaching the igniter.
Solution:
- Turn off and unplug the dryer.
- Clean the burner assembly thoroughly, ensuring all passages are free of obstructions.
3. Faulty Flame Sensor
The flame sensor monitors the igniter and detects the heat it produces. If it fails, it won’t signal the gas valve to release gas.
Solution:
- Check the flame sensor for any signs of wear or corrosion.
- Test the flame sensor with a multimeter for continuity. If found defective, replace it to ensure proper monitoring of the igniter.
4. Malfunctioning Igniter
Even if the igniter glows, it might not be hot enough to ignite the gas. This can happen if the igniter is nearing the end of its lifespan.
Solution:
- Inspect the igniter for any visible damage.
- Test the igniter with a multimeter to ensure it’s functioning correctly. If not, a replacement is in order.
5. Gas Supply Issues
It’s possible that there’s an issue with the gas supply itself, which can be due to multiple reasons like a closed valve.
Solution:
- Ensure that the gas valve supplying the dryer is fully open.
- Check for any potential leaks or blockages in the gas line.

Why Gas Dryer Igniter Glows Then Shuts Off
This scenario is not uncommon and can be quite puzzling. The igniter glowing and then shutting off without a flame can be due to faulty gas valve solenoids. These solenoids, responsible for controlling the flow of gas to the burner assembly, may be malfunctioning.
In cases like this, the solenoids might allow the igniter to glow initially but then fail to release the gas, leading to the igniter shutting off.
The solution typically involves checking the solenoids for continuity using a multimeter and replacing them if found defective.
Gas Dryer Ignitor is Not Glowing!
An igniter that doesn’t glow at all indicates a completely different set of challenges. It could be due to a broken igniter or an interruption in the electrical pathway that powers it. In some cases, a faulty thermal fuse might be the culprit, cutting off the power to the igniter.
To resolve this, one must first inspect the igniter for visible damage. If it appears intact, testing it with a multimeter for continuity can confirm its functionality.
If the igniter is in good shape, checking the thermal fuse and other associated electrical components might unveil the root of the problem.
