Dryer Ignitor Not Glowing

The dryer ignitor not glowing indicates a malfunction in the ignitor, which may require replacement or repair. If the ignitor fails to glow, it is likely due to a faulty ignitor, a defective temperature switch, or a broken heating element.

Possible Causes For A Dryer Ignitor Not Glowing

In case your dryer ignitor is not glowing, there are several possible causes that need to be considered. One probable cause could be a faulty ignitor. The ignitor is responsible for generating the heat required to ignite the gas in the dryer. It will fail to glow and ignite the gas if it becomes defective.

Another potential cause is a defective thermostat. The thermostat regulates the temperature inside the dryer, and if it malfunctions, it may prevent the ignitor from glowing properly. Lastly, a broken thermal fuse could be the culprit.

The thermal fuse is a safety device that shuts off the dryer if it overheats. If it is blown, it will interrupt the circuit and prevent the ignitor from glowing. It is essential to check these three components thoroughly to identify and resolve the issue with your dryer ignitor.

Signs Of A Dryer Ignitor Not Glowing

One of the common issues with a dryer is when the ignitor fails to glow. This can be indicated by a few key signs. Firstly, if there is no heat in the dryer during a cycle, it could be due to a faulty ignitor. Secondly, an unresponsive control panel could also point towards a non-glowing ignitor. Lastly, if your clothes are staying wet even after a complete drying cycle, it may be caused by a malfunctioning ignitor. It is important to address this issue promptly to avoid further damage to your dryer.

Testing The Dryer Ignitor

Safety precautions:

Before starting any work on your dryer, it is essential to ensure your safety. Make sure to disconnect the power supply to the dryer by unplugging it or switching it off at the circuit breaker. Additionally, it is recommended to wear protective gloves and goggles to prevent any potential injuries.

Inspecting the ignitor for visible damage:

To begin troubleshooting the issue of a dryer ignitor not glowing, visually inspect the ignitor carefully. Look for any signs of physical damage such as cracks or breaks. If there is visible damage, the ignitor will need to be replaced.

Using a multimeter to test the ignitor’s continuity:

If there is no visible damage, the next step is to use a multimeter to test the ignitor’s continuity. Set the multimeter to measure resistance and touch the ignitor’s terminals with the multimeter leads. If the ignitor is functioning properly, it should show a reading of around 50 ohms. If the reading is significantly different or shows zero resistance, it indicates a faulty ignitor that needs to be replaced.

Replacing A Faulty Dryer Ignitor

When your dryer ignitor is not glowing, it is an indication of a faulty component that needs to be replaced. To successfully replace the ignitor, you will need a few tools and replacement parts. Here is a step-by-step guide to help you through the process:

Gathering The Necessary Tools And Replacement Parts

To begin, make sure you have the following tools and replacement parts:

ToolsReplacement Parts
ScrewdriverNew ignitor (compatible with your dryer model)
Needle-nose pliers 

Disconnecting The Power Supply

Prior to starting any repair work, ensure that the power supply to the dryer is disconnected. This guarantees your safety throughout the process.

Removing The Old Ignitor

Next, locate the old ignitor, which is typically positioned near the burner assembly. Use your screwdriver to remove any screws or brackets holding the ignitor in place. Once loose, carefully disconnect the wires attached to it and set the old ignitor aside.

Installing The New Ignitor And Reconnecting The Wires

Take the new ignitor and connect the wires in the same manner as the previous ignitor was attached. Use your screwdriver to secure the ignitor back into place with any necessary screws or brackets. Once everything is securely in position, connect the power supply back to the dryer.

By following these steps, you can successfully replace a faulty dryer ignitor and have your dryer up and running again in no time.

Checking And Replacing A Defective Thermostat

Understanding the role of the thermostat in the dryer: The thermostat is a crucial component responsible for temperature regulation within the dryer. It ensures that the dryer doesn’t overheat or stay too cold. In case of a malfunction, the thermostat may prevent the ignitor from glowing, indicating a faulty thermostat as a possible cause of a dryer not heating up.

Testing the thermostat for continuity: To check if the thermostat is defective, use a multimeter to measure its continuity. Disconnect the dryer’s power supply, locate the thermostat, and remove its wires. Set the multimeter to the continuity or ohms setting and touch the probes to the thermostat’s terminals. If the multimeter shows no continuity, the thermostat is faulty and needs replacement.

Safely replacing a faulty thermostat: Begin by disconnecting the dryer from its power source. Remove any components blocking access to the thermostat, carefully detach its wires, and remove the old thermostat. Install the new thermostat in its place, reconnect the wires, and reassemble any removed parts. Finally, restore power to the dryer and test if the ignitor glows.

Examining And Replacing A Broken Thermal Fuse

Understanding the function of the thermal fuse: The thermal fuse is a safety device that is designed to prevent overheating in the dryer. It is a small, rectangular component located near the heating element. When the dryer temperature reaches an unsafe level, the thermal fuse blows and interrupts the electrical flow to the heating element, shutting off the dryer.

Testing the fuse for continuity: To determine if the thermal fuse is the cause of the dryer not heating up, you can perform a continuity test. Start by unplugging the dryer and removing the back panel to access the thermal fuse. Using a multimeter set to the continuity mode, touch the probes to the terminals of the thermal fuse. If you get a reading of infinite resistance, then the thermal fuse is blown and needs to be replaced.

Replacing a blown thermal fuse: If the continuity test indicates that the thermal fuse is blown, it is important to replace it. Start by ordering a replacement thermal fuse of the same specifications. Once the new fuse arrives, unplug the dryer, remove the back panel, and disconnect the wires from the old fuse. Install the new fuse and reattach the wires. Finally, reassemble the dryer and test it to ensure that the ignitor is now glowing and the dryer is heating up properly.

Additional Troubleshooting Steps

The dryer ignitor not glowing could be a result of various issues. When troubleshooting, it is important to consider additional steps to identify the problem.

Checking For Blockages In The Venting System:

Inspect the venting system for any debris or obstructions that may be blocking airflow. Clear any blockages found to ensure proper ventilation.

Verifying Proper Voltage Supply To The Dryer:

Using a multimeter, check the power supply to the dryer. Ensure that there is a consistent flow of electricity and that the voltage matches the manufacturer’s specifications.

Inspecting Other Potential Issues:

Examine the timer or control board for any signs of damage or malfunction. Replace any components that are worn out or defective.

By following these additional troubleshooting steps, you can pinpoint the cause of your dryer ignitor not glowing and take appropriate action to fix the problem.

Preventive Maintenance To Avoid Ignitor Issues

Preventive maintenance is key to avoiding ignitor issues in your dryer. Regularly cleaning the lint filter is the first step to prevent lint buildup, which can inhibit the ignitor from glowing. Lint buildup can also occur in the venting system, so it’s important to clear it out regularly to ensure proper airflow and prevent overheating.

Conducting routine inspections of dryer components, such as the ignitor, thermostat, and wiring, can help identify any potential issues before they become major problems. Replacing worn or faulty parts in a timely manner can prevent the ignitor from failing and prolong the lifespan of your dryer.

By taking these preventive measures, you can maintain the efficiency and performance of your dryer and avoid the frustration of a non-glowing ignitor
