Troubleshooting Made Easy: How to Check Gas Dryer Igniter Like a Pro

Is your gas dryer refusing to heat up? The culprit might be a faulty igniter. Learning how to check gas dryer igniter is a valuable skill for any homeowner. This blog post will guide you through the process, helping you diagnose the issue and potentially save you the cost of a service call.

Understanding the Gas Dryer Igniter

The igniter in your gas dryer plays a crucial role in the drying process. It’s a small, ceramic component responsible for generating a spark that ignites the gas burner. When the igniter fails, the burner won’t light, and your clothes will remain damp.

Signs of a Faulty Igniter

Before you start troubleshooting, it’s important to identify the symptoms of a faulty igniter. Here are some common signs:

• No heat: The most obvious sign is that your dryer isn’t producing any heat.
• Clicking sounds: You might hear a clicking sound coming from the dryer as the igniter tries to spark but fails.
• Smell of gas: If you smell gas, it’s a sign that the igniter isn’t working correctly and the gas is not being ignited.
• Blinking lights: Some dryers have error codes displayed by blinking lights. Consult your dryer’s manual to see if a specific code indicates an igniter issue.

Important Note: If you smell gas, immediately turn off the dryer and the gas supply. Ventilate the area and call a qualified technician.

Safety First: Disconnecting the Gas and Power

Before you start checking the igniter, it’s essential to take safety precautions.
1. Turn off the gas supply: Locate the gas valve for your dryer and turn it off.
2. Unplug the dryer: Disconnect the dryer from the electrical outlet.

Checking the Igniter: A Step-by-Step Guide

Now that you’ve ensured safety, follow these steps to check the igniter:
1. Locate the igniter: Open the dryer door and locate the igniter. It’s usually a small, ceramic component near the burner.
2. Inspect for damage: Carefully examine the igniter for any visible signs of damage, such as cracks, burns, or broken wires.
3. Test the igniter: If the igniter looks intact, you can test it using a multimeter.

• Set the multimeter to the ohms setting.
• Touch the probes to the two terminals on the igniter.
• If the multimeter shows a reading of 0 ohms, the igniter is good. If the reading is infinite, the igniter is faulty.

Replacing the Igniter

If the igniter test reveals a faulty component, you’ll need to replace it.
1. Purchase a new igniter: Obtain a new igniter that’s compatible with your dryer model. You can find replacement parts at appliance stores or online retailers.
2. Disconnect the old igniter: Carefully disconnect the wires from the old igniter.
3. Connect the new igniter: Connect the wires to the new igniter, ensuring they are securely attached.
4. Reconnect gas and power: Turn the gas supply back on and plug the dryer back into the outlet.
5. Test the dryer: Run a test cycle to ensure the dryer is heating properly.

Troubleshooting Other Potential Issues

While a faulty igniter is a common cause of heating problems, other issues could be at play.

• Gas valve: The gas valve might be malfunctioning, preventing gas from reaching the burner.
• Thermocouple: The thermocouple is a safety device that shuts off the gas flow if the flame goes out. A faulty thermocouple can prevent the burner from staying lit.
• Burner: The burner itself might be clogged or damaged, preventing proper combustion.

Time to Call a Professional?

If you’re not comfortable troubleshooting your dryer or if the issue persists after replacing the igniter, it’s best to call a qualified appliance technician. They have the expertise and tools to diagnose and repair complex dryer problems.

Moving Forward: Keeping Your Dryer in Top Shape

Regular maintenance can help prevent dryer problems and extend its lifespan.

• Clean the lint trap: After each use, clean the lint trap to prevent lint buildup that can restrict airflow and cause overheating.
• Clean the dryer vent: At least once a year, clean the dryer vent to remove lint and debris. A clogged vent can reduce efficiency and increase the risk of a fire.
• Inspect the dryer: Periodically inspect the dryer for any signs of damage or wear and tear.
