Check the washer drain hose for clogs.

check outside of house for any obstructions to the outlet. make sure the vent is clean

clean out lint filter check the vent hose make sure you are getting a air flow out your vent hose if not its blocked inside no air no dry it need air to dry cloths heat only will not dry plenty of air heat quicker drying

you could have bad gas coils.if the timer doesn't advance in auto dry most likely you're having heat problems,when the dryer heats and then the heat shuts off then the timer will advance,when the heat comes back on the timer stops,it does this until the clothes are dry.gas coils when starting to fail will work normally until they get hot and then no heat until the coils cool down then they will work again,on time dry the timer just keeps counting down until the time runs out no matter what's happening to the dryer.i've seen the coils fail after the first 10 minutes and other times for 20 to 30 minutes but usually if the load is big and in time dry the clothes will feel warm and you'll need to dry them a second time to get them fully dry,also while you're in ther you should clean out the dryer at least once a year,clean out the duct that the lint filter slides into,vacuum out the cabinet where the motor is and blow out the vent line,if it's a long run i use a leaf blower to blow out the line,remove it from the back of the dryer,stick the leaf blower into the vent line and blow it out,i've blown out birds nest out of some lines, your clothes will dry on time,you won't go through so many parts and you won't have to worry about a dryer fire,the gas coils are on top of the gas valve,remove the two phillips screws,lift off the cover and change out the coils.next time you use the dryer keep an eye on it,after it runs for 20 minutws start checking it,you'll hear a click,then another click and the flame will lite,look into the gas tube and if the flame isn't liting then you have bad gas coils.

If the flame is shutting of before it reaches the operating temperatures the likely failure is a restricted venting system. There is a high limit thermostat that will cause the flame to shut off if there is a lack of airflow due to a restriction in the vent system. Remove the lint filter screen and clean in with soap and water. The filter may appear clean but it could have a clear film of fabric softener residue covering it causing a restriction in the air flow too. After cleaning the filter reinstall it before running the next test.

For testing purposes only, disconnect the dryer vent hose from the back of the dryer and put a normal load of clothes in the dryer and start the dryer. If the clothes dry in the normal amount of time that would confirm a restriction in the vent hose or the venting system. NOTE: Do not leave the vent hose disconnected after running the test. Reconnect the vent hose.

You will likely find the clothes drying in the normal amount of time indicating a restriction in the venting.

unplug the machine for 5 minutes that should reset it

Check your vent. Inspect the dryer venting from the rear of the dryer to the outside vent hood of the home.
If there's a restriction in the vent--the clothing in the dryer takes longer to dry.
When an LG dryer is functioning normally---the time required to dry laundry is determined by the *Sensor* located on the drum side of the lint filter housing and by the main control board.
When laundry is near dry--any Time Remaining on the control panel that is *not* needed will be eliminated---except for the last 6 minutes.
The final 6 minutes of any LG automatic cycle is for cooling down the laundry before the dryer ends the cycle.
If a dryer *counts down* to the last 6 minutes but the laundry is still not dry--the computer will allow the dryer to run until the laundry has dried or defaults (not drying within the additional time allowed).
Dryer vents that are longer than 8 feet with more than (2) 90 degree turns--can affect drying performance.
Setting the DRY LEVEL selector to *Very Dry* will solve most dryability issues. In homes with abnormally long vents--even the longer run time in the *Very Dry* setting is usually not sufficient to dry laundry loads.
Reducing the length of the vent or starting a second cycle becomes necessary to fully dry the clothing.
If a second cycle was started---only the amount of time that is needed to dry laundry will be used before dropping to 6 minutes and then the cycle will end with dry laundry. Bonus:
LG DRYER

Problem:
The dryer has an auto dry feature which never fully dries the clothes so we wind up manually setting the dry time to an hour.
Solution:
LG gas dryers are VERY temperamental in long vent set-ups. If fabric softener sheets are used in the dryer--clean the two stainless steel strips of metal on the lint filter housing with a SCOTCHBRITE PAD--scrub back & forth several times to remove the waxy residue from the fabric softener sheets. Most,if not all manufacturers do *not* recommend using sheets in dryers that have a moisture sensor (electrodes).
However--using a SCOTCHBRITE pad keeps the wax off those sensors which can be seen if looking *into* the dryer drum and at the lint filter housing.
If only *liquid* fabric softener is used in the washer--clean the dryer sensors once a month. Liquid softener also contains wax which can slowly accumulate on the dryer sensors from the laundry washed in the washer.

You need to check the venting. Take the vent hose off the back of the dryer and try drying a load with it off and see if it will fully dry. If so, clean the vent hose.

the warning does not strictly mean filter only
there is a lint blockage somewhere in the vent system and there is only a single response the dryer knows to make
fan
fan housing
duct
outside vent
could all be sufficiently blocked to set off the warning
