Quick answer
Do not locate, tighten, adjust, test or replace a gas-adjustment screw yourself. Treat any gas odor, hissing or suspected gas leak around an LG dryer as an immediate safety issue: do not light an appliance, touch electrical switches or use a phone inside; clear everyone from the area and call the gas supplier or fire department from outside. If the dryer gas shutoff is plainly accessible without moving the dryer or entering an unsafe area, follow LG's instruction to close it; otherwise leave it for the gas supplier. Keep the dryer out of service until a qualified installer, service agency or gas supplier inspects it. The screw allegation is not proof of a specific failed part, and the available evidence does not support a model-free adjustment or restart procedure.

Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
If gas is smelled, heard or suspected around the LG dryer, stop using it and clear the room, building or area of all occupants. Do not light any appliance, touch a switch or use a phone inside.
Expected result: Gas odor, hissing, an abnormal flame report or uncertainty about the gas path is present.
Next step: Leave immediately and call the gas supplier or fire department from outside or a neighbor's phone.
Why this matters
Why: This is a possible gas leak, not a condition to diagnose by touching or operating an adjustment screw.
-
Check 2
Only if the dryer gas shutoff is plainly reachable from a safe position without moving the dryer, entering the suspected gas area or touching electrical controls, close it as directed by the gas supplier or responder. Do not approach it when doing so is unsafe.
Expected result: The valve is safely accessible without entering a hazardous area, or reaching it would require approaching the dryer or suspected leak.
Next step: If safely accessible, report the shutoff to the gas supplier and remain outside. If not, leave it untouched and wait for the gas supplier or emergency responder.
Why this matters
Why: LG identifies the individual gas valve as the shutoff point, but a shutoff instruction does not authorize unsafe re-entry or appliance movement.
-
Check 3
From outside the building or a neighbor's location, call the local gas supplier. If the supplier cannot be reached or there is immediate danger, call the fire department or emergency services.
Expected result: The gas supplier or emergency responder provides instructions or confirms the area is safe to approach.
Next step: Follow those instructions exactly. Do not return to operate, inspect or test the dryer before the all-clear.
Why this matters
Why: The gas supplier or responder controls the emergency shutoff and re-entry decision; a homeowner cannot safely identify a loose adjustment screw from the symptom alone.
-
Check 4
After the gas supplier has declared the area safe, give a qualified LG service agency, installer or gas supplier the complete dryer model and the event timeline. Include whether the report followed installation or LP conversion and whether any odor, hissing or abnormal flame was observed.
Expected result: The model and history can be documented without moving or operating the dryer, or the model remains unknown.
Next step: Keep the dryer out of service until qualified inspection. Do not open the cabinet, adjust the screw, change an orifice, test pressure or restart the dryer to reproduce the symptom.
Why this matters
Why: LG's gas-dryer documentation is model- and gas-type-specific. The reported screw may be misidentified, and no model-free adjustment or part fit can be inferred.

Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
Gas odor, hissing or suspected leakage is present near the LG dryer.
Do this next
Leave, avoid switches/phones/flames inside and call the gas supplier or fire department from outside.
Why this path and its safety boundary
Why it matters: Treat this as an active gas emergency; the alleged adjustment screw is not a safe user diagnostic target.
-
PATH 02Next step
What you see
The individual gas shutoff is already reachable from a safe location without moving the dryer or approaching the suspected leak.
Do this next
Close it only when safely accessible and consistent with gas-supplier/emergency instructions, then stay outside for inspection.
Why this path and its safety boundary
Why it matters: LG identifies the valve behind the dryer as the gas-supply shutoff, but the valve must not be reached at the cost of re-entering danger.
-
PATH 03Next step
What you see
Reaching the shutoff would require moving the dryer, entering the room with gas odor, touching switches or otherwise approaching the suspected leak.
Do this next
Do not attempt it. Evacuate and let the gas supplier or emergency responder control the shutoff and inspection.
Why this path and its safety boundary
Why it matters: The shutoff is not safely accessible to the occupant.
-
PATH 04Next step
What you see
No gas odor is present now, but someone reports a loose gas-adjustment screw or prior abnormal flame and the dryer has not been inspected.
Do this next
Do not adjust or test it. Keep the dryer out of service and arrange qualified gas-appliance inspection with the exact model and history.
Why this path and its safety boundary
Why it matters: The report is not a confirmed component diagnosis, and an odor-free moment does not prove that the dryer is safe or that the screw is the cause.
Helpful context
Understand the symptom
Treat a suspected adjustment screw as a gas-safety issue
A report that an adjustment screw is loose does not establish that the screw is the source of a leak or that it is user-adjustable. If there is gas odor, hissing, flame outside the normal burner pattern or uncertainty about the gas path, stop the dryer and clear the area. Do not open the cabinet or try to confirm the screw by touch.
Evacuate before calling
LG says not to try to light an appliance, touch an electrical switch or use a phone in the building when gas is smelled. Clear all occupants, then call the gas supplier from a neighbor's phone or another safe location; if the supplier cannot be reached, call the fire department. Do not re-enter to ventilate, inspect, move the dryer or retrieve a phone.
Close the shutoff only when safely accessible
LG's support guidance says to turn off the gas supply at the valve behind the dryer, but this does not mean moving the dryer or entering a gas-filled area. If the individual shutoff is already reachable from a safe position without operating electrical controls, follow the gas supplier's or emergency responder's instructions. If reaching it would require approaching the suspected leak, leave it alone and evacuate.
Leave the screw and gas train to qualified service
LG's gas-dryer safety and installation documents require qualified installation and service, warn against dryer disassembly, and place gas conversion and connections under qualified service or gas-supplier control. Do not tighten the alleged screw, set gas pressure, change an orifice, apply leak fluid, relight the burner or run the dryer to compare flames. After the gas supplier declares the area safe, provide the exact model and the observed timeline to the qualified technician.
When checks do not resolve it
Need a professional?
Have this ready
- complete LG dryer model and serial information after the area is safe
- whether the dryer is natural gas or LP and whether conversion or installation was recent
- which area was described as having a loose screw
- whether gas odor, hissing, abnormal flame or smoke was observed
- the gas supplier or emergency responder's instructions and findings
Common questions
FAQ
Can I tighten the loose gas-adjustment screw on my LG dryer?
No. The screw may be misidentified, and adjusting a gas-control component without the exact model and qualified procedure can create fire or explosion risk. Keep the dryer out of service and arrange qualified gas-appliance inspection.
Should I close the gas valve behind the LG dryer?
LG says to turn off the gas supply valve if gas is smelled, but only do so when it is safely reachable without moving the dryer or entering a hazardous area. Otherwise evacuate and let the gas supplier or emergency responder handle the shutoff.
Can I test the screw with soapy water or a flame?
Do not use a flame or return to test the alleged screw during a suspected leak. Leave the area and call the gas supplier; qualified service should select the inspection method after the area is safe.
What if the gas smell has stopped?
A stopped odor does not prove that the dryer is safe or that the screw was the cause. Keep the dryer off and obtain a gas-supplier or qualified-technician inspection before using it.
