LG gas dryer valve replacement costs $280–450 total in Los Angeles, Orange County, and Ventura County — $280–340 for solenoid coils only, $380–450 for the full valve assembly. OEM parts, igniter check included, gas supply verified before we start, soap leak test after installation, and 1-year warranty. The $65 diagnostic fee is waived when you approve the repair. A properly maintained LG gas dryer runs 12–15 years — most gas valve calls we get are fixable, not reasons to buy new.
Cost breakdown
How Much Does Gas Valve Replacement Cost on an LG Dryer?
Two repairs depending on what failed:
Gas valve solenoid coils only: $280–340 total. The gas valve has two or three solenoid coils that open and close electrically to allow gas flow. The coils wear out from repeated heating cycles — they're the electrical components, not the mechanical valve body. Part cost: $80–120. Labor: $180–210. This is the more common repair, especially on machines under 10 years old.
Full gas valve assembly: $380–450 total. When the valve body itself is corroded, damaged, or not seating properly — the valve leaks or doesn't fully close. Part cost: $150–200. Labor: $200–230. More common on older machines and near the coast where salt air accelerates corrosion on gas components. We see more full assembly replacements in Long Beach and Malibu than inland.
Both repairs include: gas supply line verification before we open anything, OEM parts confirmed for your specific model, soap solution leak test on every fitting after installation, igniter condition check (igniter fails alongside coils in about 30% of valve calls), and a complete heat cycle test before we leave.
Some LG models require removing the drum assembly to access the gas valve — this adds 30–45 minutes and pushes the labor toward the higher end of the range. Homes built before 2015 in Burbank and Pasadena typically have straightforward installations. Newer construction in Calabasas and Irvine with more complex laundry room configurations sometimes requires additional access work.
Gas Dryer No Heat — What We Test Before Recommending Any Parts
A gas LG dryer that runs normally but produces no heat has four possible causes that look identical from the outside. We test all four before recommending anything:
Thermal fuse — most common no-heat cause, gas or electric. Reads open on a multimeter when blown. Usually from a clogged vent — lint buildup affecting airflow also correlates with gas valve stress in Torrance and Santa Monica homes we service regularly. Cost: $280–350. We test this first.
Igniter — glows orange to light the gas. No glow = igniter failed. Faint glow that doesn't reach ignition temperature = could be igniter weakening or coils not opening. Cost: $280–350.
Gas valve solenoid coils — igniter glows correctly but gas doesn't flow because the coils aren't opening the valve. Trickier to catch visually since everything looks right. Resistance test with multimeter confirms. Cost: $280–340.
Gas supply issue — shutoff valve partially closed, pressure too low, or flexible connector kinked. We verify gas is reaching the dryer at correct pressure before recommending any parts. Free check during the diagnostic visit.
In older Pasadena and Glendale homes where gas lines haven't been touched in decades, we find supply issues more often. In newer Irvine and Moorpark construction, it's almost always the igniter or coils.
Coils vs Full Assembly — How We Decide On-Site
We replace coils only when the valve body is in good condition — clean seating surfaces, no corrosion, opens and closes smoothly. Most valve calls on machines under 10 years old are coil replacements.
We recommend the full assembly when the valve body shows corrosion or mineral deposits, or when the valve doesn't seat cleanly (gas smell or incomplete shutoff detectable with soap test). Coastal areas — Malibu, Long Beach, parts of Torrance near the water — see more full assembly replacements because salt air corrodes gas components faster. Coils on a compromised valve body fail again sooner, so the full assembly is the right call when the body is the issue.
Is My LG Dryer Gas or Electric?
We get asked this on almost every no-heat call. Quick check from behind the dryer:
Gas dryer: flexible metal gas line connected to the wall, standard 120V plug (same as a regular appliance).
Electric dryer: large 240V plug with 3 or 4 flat prongs — noticeably larger than a standard outlet. No gas line.
Gas valve and igniter repairs apply only to gas dryers. Electric dryer no heat = heating element or thermal fuse.
Can I Replace an LG Dryer Gas Valve Myself?
Gas line work involves safety risks that make this one we'd recommend leaving to a professional. Specifically: gas fittings that aren't fully tightened or properly sealed can leak slowly without being immediately obvious — and a slow gas leak in a laundry room is a serious hazard. The soap leak test we run after every installation catches fittings that feel tight but aren't. Without that test, a small leak can go undetected.
That said, the coil replacement itself is straightforward — the coils are electrical components that unplug and swap without touching the gas fittings at all on some models. If you're comfortable confirming your model doesn't require moving the valve, coil replacement is low risk. Full valve assembly replacement involves disconnecting and reconnecting the gas line — that's where we'd strongly recommend a technician.

Questions About LG Dryer Gas Valve Replacement Cost
How much does LG dryer gas valve replacement cost?
$280–340 for solenoid coils only, $380–450 for full valve assembly. Both include OEM parts, gas leak test, igniter check, and 1-year warranty. The $65 diagnostic fee is waived when you approve the repair. We determine which is needed during on-site diagnosis before recommending either.
How do I know if it's the gas valve, igniter, or thermal fuse?
All three cause the same symptom — dryer runs normally with no heat. We test all three before recommending any parts. Thermal fuse most common and least expensive ($280–350). Igniter: no glow visible when running. Valve coils: igniter glows but burner never lights. We work in order from least to most expensive.
Should I replace just the coils or the full gas valve assembly?
Coils only when the valve body is in good condition — clean, no corrosion, seats properly. Full assembly when the body is corroded or doesn't seal cleanly after soap test. Coastal homes in Malibu and Long Beach more often need the full assembly. We assess during diagnosis and recommend based on what we find.
Can I replace an LG dryer gas valve myself?
Coil replacement is low risk on models where coils unplug without touching gas fittings. Full valve assembly replacement involves disconnecting and reconnecting the gas line — we recommend a technician for that work. A soap leak test after reconnection is essential and easy to miss if you don't know to look for it.
How long does LG dryer gas valve replacement take?
Coil replacement: 1–1.5 hours including diagnosis, leak test, and heat cycle confirmation. Full assembly: 1.5–2 hours. Models requiring drum removal to access the valve: add 30–45 minutes.
Is my LG dryer gas or electric?
Gas: flexible metal gas line at the back, standard 120V plug. Electric: large 240V plug with 3–4 flat prongs, no gas line. Gas valve repairs apply only to gas dryers.
