LG Washer Error Code gAS

The gAS code on an LG gas dryer model indicates that the appliance is not receiving an adequate gas supply to complete its ignition cycle. Although it may appear in the context of an LG washer setup, this code applies only to gas dryer units. The most common reason is that one or both gas shutoff valves in the supply line are closed or not fully open. Correcting the valve position typically resolves the error.

The error itself is a protective indicator rather than a sign of a gas leak. However, any time you are working around gas appliances, you should check for the smell of gas and use a leak detection solution on all connections. If you smell gas at any point, leave the area immediately, avoid operating electrical switches, and contact your gas utility provider. Do not attempt repairs while a gas odor is present.

Performing a reset by unplugging the dryer or cycling the power will temporarily clear the displayed code, but the error will return on the next cycle if the underlying gas supply issue has not been resolved. The code will only stay cleared once the dryer can successfully complete an ignition cycle with adequate gas pressure. Always address the root cause before relying on a reset.

Start by locating the appliance shutoff valve on the gas line directly behind the dryer and confirm the handle is parallel to the pipe, meaning fully open. Then check the main gas shutoff at your home's meter and verify other gas appliances are working. If supply is confirmed but the error persists, inspect the flexible connector hose for kinks and consider testing the internal gas valve solenoid coils for continuity.

If the issue is simply a closed shutoff valve, there is no repair cost involved. If the flexible gas connector hose needs replacement, parts typically run in the range of $15 to $40. A failed internal gas valve solenoid coil assembly can cost between $30 and $80 for the part, with professional labor adding $75 to $150 depending on your location and the technician's rates.
