LG Dryer 9A5 — What It Means & How to Fix It
Also shown as gAS on some models.
9A5 — which spells 'gAS' on an LG dryer's display — appears on gas models when the dryer isn't receiving proper gas supply, so the drum turns but the clothes stay cold, and after checking that the gas valve is open the remaining causes are burner parts for a technician.
What this code means
On a gas dryer the burner needs a steady gas supply to light, and 9A5 is LG's way of saying that supply isn't reaching it. The seven-segment display renders the letters G-A-S as '9A5'. The safe things to check are external — a shutoff valve that's closed and a kinked or disconnected supply line — while the igniter, flame sensor, and gas valve inside are technician-only parts.
9A5 is specific to gas LG dryers; an electric model won't show it. Once you've confirmed the gas is turned on and the line is sound, there's no safe user repair — the burner assembly must be serviced by a qualified technician.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Gas shutoff valve behind the dryer closed or only partly open | Common | Yes — check supply only |
| Kinked, crushed, or disconnected gas supply line | Occasional | Partly — inspect only |
| Low gas pressure to the home or appliance | Occasional | No — professional job |
| Failed igniter, flame sensor, or gas-valve coils | Common | No — technician job |
What you can try yourself
- Turn the dryer off and confirm the gas shutoff valve behind it is fully open — this only means looking at and turning the valve handle, not touching the gas connections.
- Check that other gas appliances in the home are working, which tells you whether the whole house is affected or just the dryer.
- Look along the flexible supply line for an obvious kink or a loose connection, but don't disconnect or tighten gas fittings yourself.
- Turn the dryer off at the breaker for a couple of minutes and back on to clear a one-time reading, then try a heated cycle.
- If 9A5 stays with the gas confirmed on, stop here and book a technician — the igniter, flame sensor, and gas valve are not safe to test or replace yourself.
When to call a technician
- The dryer runs but never heats, and 9A5 stays after you've confirmed the gas is on.
- You catch even a faint gas odor — turn the dryer off, open windows to air the room out, and if it's strong, leave and phone your gas utility from outside.
- The problem started right after the dryer was moved, reconnected, or switched between natural gas and LP.
Typical professional repair cost: Gas dryer ignition repairs — igniter, flame sensor, or gas-valve coils — generally run $150–$350 with labor, depending on the part.
Frequently asked questions
What does 9A5 mean on an LG dryer?
It's the display spelling 'gAS' — the dryer isn't getting proper gas supply, so it won't heat. First confirm the gas shutoff valve behind the dryer is fully open and the supply line isn't kinked. If gas is definitely reaching it, the igniter or gas valve is likely at fault and needs a technician.
Why is my LG gas dryer not heating and showing 9A5?
9A5 means no usable gas is getting to the burner, so the drum spins but stays cold. The safe checks are the shutoff valve and the supply line. Beyond that, the igniter, flame sensor, or gas-valve coils are the usual culprits — all gas-burner parts that a qualified technician should service.
Is a 9A5 code dangerous?
The code itself is the dryer safely refusing to heat without proper gas, which is good. The caution is the gas system: never test or repair the burner, valve, or gas line yourself. And if a gas smell ever appears, shut the dryer off, air out the space, and reach your gas utility — from outside the home if the odor is strong.

- LG Dryer d80 d80 is LG's Flow Sense system telling you the exhaust duct is about 75–80% restricted: the dryer keeps running but dries slowly, so treat it as an early warning to clean the lint filter and the full vent line before the blockage gets worse.
- LG Dryer d90 d90 — and the more severe d95 — is LG's Flow Sense system reacting to a badly blocked exhaust of 90% or more by cooling the dryer down and stopping the cycle, so unlike the milder d80 you have to clear the vent before it will run properly again.
- LG Dryer dE dE tells you an LG dryer can't confirm its door is latched shut, so it won't spin the drum — usually because laundry is caught in the seal, the door wasn't pushed firmly enough, or the door switch is worn.
- LG Dryer tE1 tE1, and the related tE3, means an LG dryer has detected a problem with its thermistor — the sensor that tracks drum temperature — so a factory reset clears a one-off glitch, but a code that keeps returning points to a failing sensor for a technician.
