LG Dryer Error Code gAS
The gas dryer is not getting gas, most often because one of its shutoff valves is closed. Open both the house and dryer gas valves fully and confirm other gas appliances work; if you smell gas, leave and call the utility instead.
Also shown as: GAS
Common causes
- Dryer's own gas shutoff valve closed
- House gas shutoff valve closed
- Gas service interrupted by the utility
- Gas line kinked or not connected on a new installation
What to check, in order
- Confirm that both the house gas shutoff and the shutoff valve behind the dryer are fully open
- Check that other gas appliances in the home, such as a stove or water heater, are working normally
- If the dryer was just installed, ask the installer to check the gas line connection
- If both valves are open and other appliances work but gAS returns, book service
- If you smell gas at any point, do not touch electrical switches: leave the house and call your gas utility
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code gAS, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
