Step-by-Step DIY Fix Guide
- SAFETY: If you smell gas at any point, do not operate any electrical switches. Leave the house immediately, leave the door open, and call your gas utility company from outside. Do not re-enter until cleared by the utility.
- With no smell of gas present, check that the gas shutoff valve behind the dryer is in the fully open position — the valve handle should be parallel to the gas line.
- Confirm gas is flowing to other gas appliances in the home (stove, water heater) — if none of them work, the issue is with the gas supply to the home.
- If the gas supply is fine but GAS persists, unplug the dryer and do not attempt internal repairs.
- Call an LG-certified technician — gas valve solenoid, igniter, and flame sensor replacement on a gas dryer must be performed by a qualified technician.
If the code comes back
- GAS appears on any cycle — do not attempt internal gas component repairs yourself
- You smell gas near the dryer at any time — treat this as an emergency
What This Error Means
Error GAS on your LG dryer means: The dryer has detected an issue with the gas supply. Either the gas is not flowing when the igniter calls for it, or the gas valve solenoids have failed. This code appears on LG gas dryers only. The dryer's self-diagnostic system has detected this condition and stopped or paused the cycle.
The most frequent cause is gas supply valve behind the dryer not fully open — turned partially closed during installation or servicing. Work through the causes and fix steps below in order — many LG dryer errors are resolved without a service call.
LG's official guidance classifies GAS as a technician-only fault. A power reset is the only DIY step — if the code returns, contact LG Support at 1-800-243-0000.
Gas-related dryer codes require immediate attention. Always check for the smell of gas first — if detected, evacuate and call the gas utility emergency line. If no gas smell is present, the issue is most likely a mechanical component failure such as a solenoid or igniter, which requires a qualified technician.
Most Likely Cause by Symptom
The LG dryer may stop, pause, or refuse to complete the cycle normally.
Likely cause: Gas supply valve behind the dryer not fully open — turned partially closed during installation or servicing
Check first: SAFETY: If you smell gas at any point, do not operate any electrical switches. Leave the house immediately, leave the door open, and call your gas utility company from outside. Do not re-enter until cleared by the utility.
Common Causes
- Gas supply valve behind the dryer not fully open — turned partially closed during installation or servicing
- Gas supply to the home interrupted — utility outage or main shutoff closed
- Gas valve solenoids inside the dryer have failed — the valves are not opening to allow gas flow to the burner
- Igniter failure — gas is present but the igniter is not lighting it, causing the valve to cut off as a safety measure
- Flame sensor (radiant sensor) failure — sensor is not detecting the flame and cutting gas off immediately after ignition
What Not to Do
- Do not attempt to replace gas valve solenoids, the igniter, or any gas line components yourself — gas appliance repairs must be performed by a qualified technician
- Do not ignore the smell of gas — evacuate immediately and call the gas utility emergency line
Model and Display Variation Notes
Model-family notes
- LG dryer display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Service option
LG service visit if the warning returns after the basic checks are complete.
Manual and model check
Check your exact model and manual before ordering any LG dryer parts.
Common parts
- Gas valve solenoid kit if solenoids have failed ($20–$60)
- Igniter if igniter is broken ($15–$40)
- Radiant flame sensor if sensor has failed ($10–$25)
This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.
When Not to Keep Troubleshooting
GAS appears on any cycle — do not attempt internal gas component repairs yourself
- You smell gas near the dryer at any time — treat this as an emergency
How to Prevent It Recurring
- Have the dryer's gas connection and components inspected by a qualified technician every 5 years as part of routine maintenance
Related Error Codes
nP
The dryer is running but the heating element is receiving no power. Clothes will tumble but will not dry — the air is not being heated. This code indicates an electrical supply problem rather than a failed element.
tE1
The dryer has detected a fault in one of its thermistors (temperature sensors). tE1 typically indicates the exhaust thermistor, tE2 the inlet thermistor, and tE3 a secondary thermistor — all three variants indicate the same class of problem at different sensor locations. The dryer has stopped to prevent overheating.
