Common Symptoms & Causes

If your LG DLGX5501V exhibits any of the following symptoms, it’s likely that the gas valve solenoid has failed, preventing proper ignition or heating.

• The dryer runs but produces no heat after the drum starts spinning.
• You hear the igniter glow, but the burner never lights or shuts off immediately.
• The dryer repeatedly attempts ignition in short cycles without sustaining a flame.
• Clothes remain cold and damp after a complete drying cycle.

Typically, this issue arises from worn solenoid coils inside the gas valve assembly. As these coils weaken over time, they lose the magnetic force necessary to open the valve and allow gas to flow to the burner.

Safety First

• Unplug the dryer from the power outlet before starting any repair — never work on a live appliance.
• Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
• Take photos with your phone before disconnecting any wiring harnesses or connectors.
• Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

Before you dive into any internal components, unplug the dryer from the wall outlet and close the manual gas shutoff valve on the supply line behind the unit. Skipping either step puts you at risk for electric shock or gas exposure. Let the dryer sit unplugged for at least 5 minutes to ensure any residual charge in the capacitors has dissipated. Keep in mind that the LG DLGX5501V uses an electronic glow-bar igniter with no standing pilot light, so there’s no pilot flame to extinguish.

Step 2

Remove the rear panel by unscrewing the five ¼-inch hex screws and setting the panel aside. This gives you access to the full burner and gas valve assembly. Locate the gas valve; it’s identifiable as a steel housing mounted along the burner tube with two or three cylindrical solenoid coils clipped onto the valve body. These solenoids are the most common failure point on this model: when a coil burns out, it remains closed and prevents the burner from receiving gas, even if the igniter glows correctly.

Step 3

Disconnect the wire leads from each solenoid coil one at a time and test each one using the Rx1 ohms setting on your multimeter. The primary coil should read approximately 1,300 ohms, while the secondary coils should read between 90 and 600 ohms. If any coil reads infinite resistance (open circuit), that coil has burned out and needs replacement. These coils are sold as a kit and snap directly off and onto the valve body, allowing you to replace only the coils and keep parts costs down.

Step 4

While you have the burner area accessible, check the igniter — the glow bar mounted just below the burner tube. A weak igniter is the second most common cause of symptoms similar to gas valve solenoid failure. Set your multimeter to Rx1 and probe the igniter terminals; a healthy igniter should read between 50 and 400 ohms. If you get a reading above 600 ohms or an open circuit, the igniter can no longer reach the temperature threshold needed to signal the solenoid coils to open. A pro tip: even if the igniter visibly glows during a cycle, a high resistance reading means it’s not glowing brightly enough to trigger the solenoids, mimicking a solenoid failure.

Step 5

You’ll also need to test the radiant flame sensor — the small bi-metal safety device clipped near the igniter. A failed sensor will prevent the solenoids from opening, regardless of the condition of the coils or igniter. At room temperature, the sensor contacts should be closed; use your multimeter set to Rx1 to confirm you get a continuity reading near zero ohms. If you get an open reading at room temperature, the sensor has tripped permanently and needs replacement. This sensor is designed to fail safe, so never bypass it or reuse a sensor that has already opened.

Step 6

Before reassembling the rear panel, make sure to close the manual gas shutoff valve so that gas cannot flow while you secure the screws. Once the panel is back in place with all five screws tightened, reopen the gas shutoff valve, plug the dryer back in, and run a full heated cycle. Watch or listen for the burner to ignite within the first two to three minutes of the heat cycle — a successful ignition with a steady flame indicates that the solenoids, igniter, and sensor are all functioning properly. If the burner still fails to light, double-check your solenoid resistance readings and ensure all wire connectors are fully seated.

Where to Buy Replacement Parts

You can find genuine OEM and aftermarket replacement parts for your LG DLGX5501V (Gas) on Amazon:

When to Call a Professional

If the issue persists after following all the steps above, the problem might involve a failed main control board, a defective heating element, or wiring that requires specialized diagnostic tools. In such a case, it’s best to contact a licensed appliance technician. For gas dryers, avoid working on the gas valve or supply line yourself; that work is typically restricted to licensed gas fitters in most regions.

How Much Does This Repair Cost?

Replacing a gas valve solenoid on the LG DLGX5501V yourself usually costs between $35–$80 for the replacement part. A professional service call for this repair typically costs $150–$300, including labor and parts. Tackling this repair on your own can save you $100–$220 or more, making it a worthwhile fix for confident home repair enthusiasts.

Frequently Asked Questions

How do I know if the gas valve solenoid has failed on my LG DLGX5501V?

The most common signs include a dryer that runs but produces no heat or a burner that ignites briefly and then shuts off. You may also hear clicking without any flame igniting.

Is it safe to replace the gas valve solenoid myself?

Yes, as long as you disconnect the dryer from power and shut off the gas supply before starting. If you smell gas at any point, stop immediately and call a professional.

How much does a replacement gas valve solenoid kit cost for the LG DLGX5501V?

Replacement solenoid coil kits typically range from $20 to $50, depending on the supplier. Opting for an OEM kit ensures proper compatibility with your specific model.

The OEM Gas Valve That Stops the Intermittent Heat Cycle on Your LG DLGX5501V

On this LG model specifically, the solenoid coil failure almost always traces back to the gas valve itself wearing out over time. Grabbing the OEM replacement valve assembly is the most direct path to a permanent fix — no guesswork, no compatibility headaches.

What works

• Direct OEM fit — no adapter kits or workarounds needed; the valve seats exactly where the failed one came out, and gas connection points line up perfectly on first try.
• Solenoid coil is factory-sealed and pre-tested, so you eliminate the risk of getting a defective replacement coil kit that leaves you troubleshooting a second time.
• Eliminates the intermittent heating symptom completely — heat comes back consistently and stays stable throughout the dry cycle, no more mid-cycle shutdowns.

What doesn’t

• More expensive than a standalone coil kit, so if your actual failure is just the coil (rare on this model), you’re paying for parts you didn’t strictly need.
• Requires shutting off gas supply at the meter and potentially bleeding lines afterward — not a five-minute swap if this is your first time working with gas appliance connections.

I’ve seen plenty of DIYers grab a cheaper coil kit first, only to realize the valve body itself was cracked or the connector was corroded — then they end up ordering this OEM valve anyway. If you’re confident the solenoid is the only problem, a coil kit saves money; but on the DLGX5501V, I almost always reach for this OEM gas valve because the failure usually involves more than just the coil.
