LG Dryer gAS Error
Gas dryers only — an electric dryer has no gAS. And note the cross-reference: on gas dryers, LG's US list says a d80 display may also indicate a lack of gas supply.
What to check first
- gAS = the dryer is not receiving gas (LG UK).
- Checks: supply valve fully ON (both shutoffs); gas line not kinked.
- Smell gas → stop, ventilate, leave, call the emergency line. That outranks this page.
- Connected properly + valve ON + still gAS → repair service.
A gAS code means, in LG's UK wording, the dryer is not receiving gas. LG's checks are two, and they are both outside the machine: check that the gas supply valve is turned ON, and check that the gas line is not kinked. Its endpoint is equally plain: if the appliance is connected properly with the gas valve ON, it will require a repair service. Gas dryers carry two shutoffs (the house supply and the dryer's own), and LG's manuals for them ask for both to be fully open — a half-open valve is a supply problem wearing a disguise.
Safety first
- Gas is the one dryer supply where the standard stop condition is not enough: if you smell gas at any point, do not run electrical checks, do not relight anything, and do not keep troubleshooting — turn the supply off if you can do so safely, ventilate, leave, and call your gas supplier's emergency line. That instruction outranks every step on this page.
- Never open the dryer's gas valve train or the sealed line connections yourself — LG routes a correctly-connected gAS to a repair service, and gas-fitting work belongs to qualified gas technicians in every jurisdiction.
- Stop condition: stop using the machine and unplug it — and do not run it again until it has been checked — if you smell burning, see smoke, find damaged electrics (a scorched plug, a melted or cut cable), or water is leaking in quantity.
Common causes
The supply valve is off or half-open
LG's first check: the gas supply valve turned ON. Dryers get serviced, moved and reconnected; a valve left closed — or opened a quarter-turn and forgotten — is the classic gAS. Both the house shutoff and the dryer's own shutoff need to be fully open.
A kinked gas line
LG's second check: the gas line not kinked. A flexible connector bent sharply when the dryer was pushed back restricts the flow exactly like a closed valve reads to the dryer.
Step-by-step checks
- Check the gas supply valve is ONConfirm the supply valve is turned ON — fully open, at both the house shutoff and the dryer's own shutoff valve.
- Check the gas line is not kinkedFollow the line's visible run: no sharp bends, no section crushed by the dryer's feet or frame when it was pushed into place.
- Connected properly + valve ON + still gAS → repair serviceLG's endpoint, verbatim in effect: if the appliance is connected properly with the gas valve ON, it will require a repair service.
When to call a technician
Service is LG's stated endpoint once the valve and line check out. Quote gAS, and say plainly that the valve is ON and the line unkinked — on a gas appliance that sentence is the whole triage, and it gets the right (gas-qualified) technician sent.
Model differences
| What you have | What changes |
|---|---|
| Gas dryer showing d80 instead | LG's US list gives gas dryers a second supply reading: a d80 display may indicate a lack of gas supplied to the unit. Work the valve and line checks on this page alongside the vent checks on the d80 page. |
| Electric dryer | No gas supply, no gAS. Its supply codes are nP and PS. |
One-page checklist — gAS
- Code read as gAS (gas dryer confirmed)
- No smell of gas — if there is, stop everything and call the gas emergency line
- Supply valve fully ON at both shutoffs
- Gas line checked: not kinked or crushed
- Still gAS → repair service booked, checks quoted

Frequently asked questions
Can a gas problem show as d80 instead of gAS?
Yes — LG's US list states that on gas dryers a d80 display code may indicate a lack of gas supplied to the unit. If your gas dryer shows d80 and is not heating, run this page's valve and line checks as well as the d80 page's vent checks; LG documents both readings.
The valve is on and the line looks fine. What is left?
LG's own conclusion: if the appliance is connected properly with the gas valve ON, the gAS code will require a repair service. Inside the machine — the valve train, the igniter circuit, the sensing — is the technician's territory, and on gas appliances that boundary is absolute.
I smell gas near the dryer. Same checks?
No. A gas smell ends troubleshooting: turn the supply off if you can do so safely, open windows, leave the area, and call your gas supplier's emergency line from outside. Do not operate electrical switches or run the dryer. Return to this page's checks only once the emergency side has cleared the scene.
