LG Gas Dryer Igniter Replacement

Is replacing the LG dryer igniter worth it?#

Yes. The igniter is a low-cost part, and an LG gas dryer that still tumbles just needs its heat restored — far cheaper than a new dryer. It is a moderate DIY job for anyone comfortable shutting off a gas supply and working at the burner.

The key is diagnosis: "no heat" on a gas dryer can be the igniter or the gas valve coils, and watching the ignition sequence tells you which.

How the gas ignition sequence works#

When the dryer calls for heat, the igniter glows red-hot, and once it is hot enough a flame sensor lets the gas valve coils open the valve so gas flows over the igniter and lights. That sequence is the whole diagnosis:

• If the igniter glows but no flame follows, the gas valve coils are usually the failure — the gas never releases.
• If the igniter does not glow at all, the igniter itself (or the thermal fuse ahead of it) is the suspect.

Watching one cycle at the burner is worth more than any parts guess.

Signs the igniter is the culprit#

• The drum turns and the cycle runs, but the clothes come out cold
• No glow at the burner during the heat call
• The dryer heats intermittently — sometimes lights, sometimes not, as a weakening igniter struggles
• Long, drawn-out drying times as ignition becomes unreliable

Because a blown thermal fuse also kills the heat circuit, check it too before assuming the igniter is dead.

Replacing the igniter yourself#

Shut off the gas supply and unplug the dryer. Access the burner assembly (usually through the front or a lower panel, depending on model), then remove the igniter carefully — it is a brittle carbide element that cracks if you touch or bump it. Handle the new one by its bracket only, never the glow tip, since skin oils create hot spots that shorten its life.

Reconnect, restore gas and power, and run a heat cycle to confirm it lights. If the igniter glows but still will not ignite, replace the gas valve coils instead — that is the other common no-heat cause.

Repair or replace the dryer?#

Replace the igniter (or coils) on any LG gas dryer that runs well — it is an inexpensive fix that fully restores heat. A new dryer only makes sense if the machine is old and other parts are failing at the same time. One ignition part is never a reason to scrap a working dryer.

LG gas dryer igniter: FAQ#

Is my no-heat problem the igniter or the gas valve coils?#

Watch the burner during a heat call. If the igniter glows but no flame follows, the gas valve coils are usually at fault; if it does not glow at all, the igniter or the thermal fuse is the suspect.

Why does my LG gas dryer tumble but stay cold?#

The drum motor and the heat circuit are separate, so the dryer can spin normally while ignition fails. A failed igniter, weak gas valve coils, or a blown thermal fuse are the common reasons for heat but no flame.

Can I touch the new igniter with my fingers?#

No — handle it only by its metal bracket. The glow element is brittle carbide, and oils from your skin create hot spots that make it fail early, so keep your fingers off the tip entirely.

Do I need to shut off the gas to replace it?#

Yes. Turn off the gas supply valve and unplug the dryer before opening the burner area. Working on a gas appliance without shutting off the supply is not safe.

The igniter glows but the dryer still will not heat — now what?#

A glow with no flame means gas is not being released, which points to the gas valve coils rather than the igniter. Replace the coils, since a glowing igniter proves that side of the circuit is working.

How long does a gas dryer igniter last?#

Typically many years, but igniters grow brittle with age and eventually crack or weaken. Rough handling and restricted airflow that makes the dryer cycle harder are what shorten their life.
