If you've got an LG gas dryer that runs but won't heat — drum spinning, motor humming, timer counting down, clothes coming out stone cold — the igniter is one of the first three things we look at. It's the component that glows red-hot to light the gas burner at the start of each cycle. When it fails, the gas flows but nothing lights it, and you get a full cycle of cold air. We handle these calls constantly across Los Angeles County, Orange County, and Ventura County. Worth knowing upfront: the igniter is only on gas dryers. If you have an electric LG, this isn't your repair — that's more likely a heating element or thermal fuse. If you're not sure which you have, gas dryers have a flexible gas line at the back and a standard 120V plug. Electric models have a large 240V plug and no gas connection.
What a Failing Igniter Actually Looks Like
Complete failure is straightforward: dryer runs a full cycle, zero heat, everything else sounds normal. But we also see partial failures that are trickier to read. The dryer starts up, you hear the burner trying to light — sometimes there's a faint clicking sound from inside the machine during the first minute or two — then it shuts off without heating. That's the igniter glowing but not getting hot enough to open the gas valve. The safety system detects no flame and cuts the burner. Some customers in Burbank and Pasadena have described their DLGX running for a few minutes, stopping, trying again, then giving up entirely. That cycling pattern is classic partial igniter failure.
On some LG models the control board will log an error code when this happens. Others just run cold with no indication anything is wrong. Either way the diagnosis is the same — we test continuity on the igniter and check the no-heat symptoms systematically before replacing anything.
How We Diagnose It
First thing is a multimeter test on the igniter — a cracked or failed igniter reads open, no continuity. You can often see the failure visually; the ceramic element is cracked or the tip is corroded. But we always test before we trust our eyes.
We also check the gas valve solenoid coils while we're in there. They sit right next to the igniter and fail for the same reasons — thermal stress over years of use. A good igniter with bad coils still won't light the burner. We had a job in Newport Beach last month where the igniter was fine and both coils had failed. Easy to miss if you only pull one part. We test both every time on gas dryer no-heat calls.
The Repair
We show up with OEM igniters for all major LG gas dryer models on the truck — DLEX3570W, DLGX3571V, and the rest of the common DLGX and DLG series you find in Beverly Hills and Glendale homes. First thing is disconnecting gas and power — we don't skip this step. Then we pull the front panel to access the burner housing, remove the old igniter and harness, and install the new OEM assembly. We reconnect everything, reassemble, and test-fire the burner multiple times to confirm proper ignition and flame. Total time is usually 45–75 minutes on-site.
Before we call it done, we check the gas connection at the back for any signs of wear and verify the exhaust vent is clear. A restricted vent makes the dryer run hotter than it should and shortens igniter life. If we find restriction, we clear it — that's part of the job on any gas dryer visit.
What It Costs
Igniter replacement runs $280–350 total for most LG gas dryers. The OEM igniter assembly is $45–85 depending on the model. Labor is $200–250, which accounts for the gas appliance safety protocol, proper testing, and the time to access and reassemble the burner housing correctly. The $65 diagnostic fee comes off the bill when you approve the repair.
If we find the gas valve coils also need replacement, that adds $60–90 for parts — we'll quote it separately before we proceed. Even with both parts the total stays well under a new gas dryer, which starts around $800 for comparable LG models. If your dryer is also dealing with other issues like a thermal fuse, we'll walk you through the combined cost honestly and let you decide whether repair makes sense.
LG Gas Dryer Models We Work On
We replace igniters on all LG gas dryer models — DLGX series (DLGX3471V, DLGX3571V, DLGX5001V), DLG series, LG Signature gas models. Igniter part numbers vary by model so we confirm the correct assembly before we arrive. Give us your model number when you call and we'll have the right part on the truck.

Questions We Get on These Calls
My LG gas dryer runs but has no heat — is it the igniter?
It's one of three things we check first: igniter, gas valve coils, and thermal fuse. All three produce the same symptom — drum spins, no heat. We test systematically before replacing anything so we know exactly what we're dealing with.
Can I keep using the dryer while it's not heating?
Mechanically you can run it, but it's not worth it. The control board keeps cycling the gas valve trying to get ignition, which stresses the valve and solenoids. Better to stop and get it diagnosed than create a secondary repair on top of the igniter.
How long do LG dryer igniters last?
Usually 8–12 years with normal use. Heavy use, power surges, or poor venting that makes the dryer run hotter than normal can shorten that. On a machine that's 10+ years old, igniter failure is expected — it's a wear item, not a defect.
Do you service Thousand Oaks and Simi Valley?
Yes — Ventura County is fully covered. Thousand Oaks, Simi Valley, Moorpark, Camarillo, Westlake Village, Newbury Park. Same-day service, usually within 4–6 hours of your call.
How long does the repair take?
Usually 45–75 minutes on-site from arrival to test cycle. We fire the burner multiple times before we leave to confirm it's lighting correctly and holding flame.
What warranty do you provide?
1-year warranty on both the OEM igniter assembly and our labor. If anything related to the repair fails in that window, we come back and handle it.
Can you come today?
Yes — call (323) 990-7550. Same-day service across Los Angeles County, Orange County, and Ventura County, typically 2–4 hours from your call.
