How to Tell If Gas Dryer Solenoid is Bad?

To determine if a gas dryer solenoid is faulty, check for a lack of heat during a drying cycle or a dryer that won’t start. This could indicate a bad solenoid.

Gas dryer solenoids are responsible for opening the gas valve to allow gas flow, and when they malfunction, it can disrupt the heating process.

Signs Of A Bad Gas Dryer Solenoid

Gas dryer solenoid showing signs of malfunction can include a dryer that runs but doesn’t heat, a gas smell when the dryer is running, or a dryer that won’t start at all. It’s important to identify and address these issues promptly to ensure efficient and safe operation.

No Heat Or Insufficient Heat

If you notice that your gas dryer is not producing any heat or is not generating enough heat to dry your clothes properly, it could be a sign of a bad gas dryer solenoid. The solenoid is responsible for controlling the flow of gas into the dryer’s burner, which is essential for generating heat. When the solenoid is functioning properly, it opens the gas valve and allows fuel to flow into the burner, leading to the production of heat. However, if the solenoid is faulty or has failed, it will not open the gas valve, resulting in no or insufficient heat. This can leave your clothes damp or take an extended time to dry, causing inconvenience and frustration.

Gas Smell

Another clear indication of a bad gas dryer solenoid is the presence of a strong gas smell around your dryer. It is normal to detect a faint gas smell when your dryer is running, as it uses gas to produce heat. However, if the gas smell becomes more noticeable or becomes overwhelming, it could mean that the solenoid is not shutting off the gas supply properly when the dryer is not in use. This can be a dangerous situation as it indicates a gas leak, which poses a serious fire hazard. If you suspect a gas leak, it is crucial to stop using the dryer immediately, turn off the gas supply, and seek professional assistance to fix the issue.

Dryer Won’t Start

One of the most frustrating signs of a bad gas dryer solenoid is when your dryer simply refuses to start. If you press the start button and nothing happens, it could be a sign of a faulty solenoid. The solenoid is responsible for allowing gas to flow into the burner when the dryer is turned on. Without a working solenoid, the burner cannot ignite, preventing the dryer from starting. This issue can be particularly inconvenient, especially when you have a load of laundry waiting to be washed and dried. When faced with a non-starting dryer, it is wise to check the solenoid as a potential culprit.

Diagnosing And Testing A Bad Gas Dryer Solenoid

Diagnosing and testing a gas dryer solenoid for faults is crucial to determine if it is functioning properly. By following specific steps and observing certain indicators, it becomes easier to identify a bad solenoid and ensure timely repairs.

Safety Precautions

Before diagnosing and testing a bad gas dryer solenoid, it is crucial to ensure your safety. Follow these safety precautions:

  • Disconnect the gas and electrical power supply to the dryer before proceeding.
  • Wear appropriate protective gear such as gloves and safety glasses.
  • Work in a well-ventilated area to avoid gas buildup.

Checking For Continuity With A Multimeter

One of the first steps in diagnosing a bad gas dryer solenoid is by checking its continuity using a multimeter. Here’s how to do it:

  1. Set your multimeter to the continuity or ohms setting.
  2. Unplug the dryer and remove the access panel to locate the gas valve solenoids.
  3. Disconnect the wires from the solenoids and touch the multimeter probes to the terminals of each solenoid.
  4. If the multimeter beeps or shows a reading close to zero, it means there is continuity, indicating that the solenoid is in good condition.
  5. However, if there is no beep or the multimeter shows a high resistance reading, it is likely that the solenoid is bad and needs to be replaced.

Testing The Valve Coils With A Multimeter

In addition to checking for continuity, you can also test the valve coils of the gas dryer solenoid using a multimeter. Follow these steps:

  1. Set your multimeter to the ohms setting.
  2. Unplug the dryer and remove the access panel to access the gas valve solenoids.
  3. Disconnect the wires from the solenoids and place the multimeter probes on the terminals of each coil.
  4. The multimeter should show a specific resistance reading within the range specified by the manufacturer.
  5. If the resistance reading is significantly higher or lower than the specified range, it indicates a defective valve coil.

Once you have determined that the gas dryer solenoid is bad, it is recommended to replace the entire solenoid assembly for optimal performance. Always consult the dryer’s manual or seek professional assistance if you are unsure of any steps or if the issue persists.

Frequently Asked Questions On How To Tell If Gas Dryer Solenoid Is Bad

How Do You Test A Gas Dryer Solenoid?

To test a gas dryer solenoid, you can use a multimeter to check for continuity on the solenoid coil. Disconnect the dryer from the power source, locate the solenoid, and remove the wires. Set the multimeter to the ohms setting and touch the probes to the solenoid terminals.

If the reading is zero or close to zero, the solenoid is functioning properly.

How Do I Know If My Dryer Gas Valve Is Bad?

To determine if your dryer gas valve is bad, look for signs such as no heat, no ignition, or a gas smell. Check if the solenoids are faulty or if there is a blockage in the gas line. If you’re unsure, consult a professional technician for accurate troubleshooting and repairs.

How Do You Test A Gas Valve Solenoid Coil?

To test a gas valve solenoid coil, you need a multimeter. Set the meter to the ohms setting. Disconnect the solenoid coil wires and place the meter probes on the coil terminals. If the reading is within the specified range, the coil is working fine.

Otherwise, it may need to be replaced.

What Does A Gas Dryer Solenoid Do?

A gas dryer solenoid controls the flow of gas to the burner. When the dryer is turned on, the solenoid opens to allow gas to flow, igniting the burner and starting the drying process.

What Are The Signs Of A Bad Gas Dryer Solenoid?

Some signs of a bad gas dryer solenoid include no heat, no flame, and continuous clicking sounds.


To sum up, identifying a faulty gas dryer solenoid is crucial in maintaining a well-functioning appliance. By paying attention to common symptoms like no heat or intermittent heat, accompanied by a clicking sound, users can determine if the solenoid is malfunctioning.

It is recommended to replace the solenoid promptly to prevent further damage and ensure efficient drying cycles. Regular maintenance and timely replacement ensure longevity and optimal performance of your gas dryer.
