Gas Dryer Igniter Troubleshooting Made Simple: A Step-By-Step Guide For Beginners

The gas dryer igniter is a crucial component in the operation of a gas dryer. It generates the spark that ignites the gas, enabling the dryer to heat up and dry clothes. When the igniter malfunctions, the dryer will not be able to generate heat, leaving clothes damp or wet. If you encounter such an issue, it’s essential to know how to check the gas dryer igniter. This comprehensive guide will provide you with step-by-step instructions on how to diagnose and troubleshoot igniter problems.

Safety Precautions

Before attempting to check the gas dryer igniter, ensure that the following safety precautions are observed:

• Disconnect the dryer from the power source.
• Turn off the gas supply to the dryer.
• Allow the dryer to cool down completely.

Tools Required

To check the gas dryer igniter, you will need the following tools:

• Multimeter
• Screwdriver
• Flashlight

Step 1: Locate the Igniter

The igniter is typically located inside the dryer drum, near the burner assembly. To access it, open the dryer door and remove the lint filter. Use a flashlight to inspect the interior of the drum and locate the igniter.

Step 2: Visual Inspection

Once you have located the igniter, perform a visual inspection. Look for any signs of damage, such as cracks, breaks, or corrosion. If the igniter appears damaged, it should be replaced.

Step 3: Test the Igniter with a Multimeter

Disconnect the igniter wires from the terminal block. Set your multimeter to the ohms setting. Place one probe on each terminal of the igniter. The multimeter should read between 100 and 200 ohms if the igniter is functioning correctly.

Step 4: Check the Igniter Gap

The igniter gap is the distance between the electrode and the burner. The correct gap is typically between 1/8 inch and 1/4 inch. Use a feeler gauge or a business card to measure the gap. If the gap is too wide or too narrow, adjust it by bending the electrode slightly.

Step 5: Clean the Igniter

Over time, the igniter can accumulate dirt and debris, which can interfere with its operation. Use a soft brush or a vacuum cleaner to gently remove any buildup.

Step 6: Test the Igniter Circuit

If the igniter passes the previous tests, the problem may lie in the circuit that supplies power to the igniter. Use a multimeter to test the voltage at the igniter terminal block. It should read between 110 and 120 volts when the dryer is running.

Step 7: Replace the Igniter

If all the above tests fail, it’s likely that the igniter is faulty and needs to be replaced. Disconnect the wires from the old igniter and remove it from the dryer. Install the new igniter and reconnect the wires.

Final Thoughts: Troubleshooting Success

By following these steps, you can effectively check the gas dryer igniter and troubleshoot any issues. Remember, safety should always be your top priority when working on any electrical or gas appliance. If you encounter any difficulties or are unsure about any step, do not hesitate to consult a qualified appliance repair technician.
