What to check, in order
- Check the gas valve
Find the gas supply valve for the dryer and make sure it's fully open.
- Check the gas line
It should be connected, and not kinked or bent.
- Newly installed?
If opening the valve doesn't fix it, or the gas line looks damaged, contact the installer.
When to call an engineer
If the dryer isn't new and the valve is fully open, LG says to contact LG for service.
Quick answers
What does the LG gAS error code mean?
A gas dryer isn't getting any gas, so it can't heat.
Can I fix LG gAS myself?
Very easy (about 5 minutes). Start with: check the gas valve; check the gas line; newly installed?. If the dryer isn't new and the valve is fully open, LG says to contact LG for service.
Is LG gAS worth repairing?
Usually free. Often a valve that's closed or only part open. Anything beyond that involves the gas supply, so it's for the installer or LG.
