Error codegAS / GAS / 9A5
ApplianceDryer
Quick answer
A gas LG dryer showing gAS, GAS or 9A5 is not receiving gas. Check the valve and the gas line first.
Model compatibility: LG reuses codes across series and model years, so gAS / GAS / 9A5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Dryer not receiving gas (display reads GAS / 9A5).
If your LG gas dryer displays gAS, GAS or what looks like 9A5, the dryer is telling you it is not getting the proper gas supply. The 9A5 you see is not a separate fault: on the display it spells out the word GAS.
What to check first
Find the gas valve and make sure it is fully open.
Look at the gas supply line and confirm it is connected to the dryer and not kinked or bent.
If the dryer is newly installed and opening the valve does not clear the message, or the gas line looks damaged, contact the installer. Gas line work belongs to a technician, so do not try to repair a damaged line yourself.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
