My LG dryer will turn on but will not start and the dry light blinks.

Clean your lint filter, and clean the entire line vent from the dryer to the outside export port, also look inside the dryer vent hook up for obstructions and remove any lint. Keeping these parts lint free will save you energy and also drying time and maintenance repairs. My dryer is 18 years old.

Hi,

If your dryer is not drying like it once did or if you just have nottaken the time to give yourself a clean dryer in a long time then youneed to do that. At least once a year the dryer cleaning should takeplace. Lint build up in the dryer duct is one of the main causesfor your dryer to fail.

The valve resistance is 1995 ohms and the ignitor is 185.
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 the 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 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.
*****************************************

LG gas dryers are more sensitive to venting length and air flow resistance. The gas burner can cause a rapid increase in temperature compared to an electric burner.
Rapid temperature rise in a gas dryer leads to premature burner shutdown (longer time required to dry laundry).
The gradual temperature increase of an electric element is more "forgiving" in homes where the dryer venting is less than ideal.

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.

check the lint filter and check venting clear

The vent is clogged.  To make sure, disconnect the vent from the dryer and run the dryer normally.  If your clothes dry normally, then have a professional vent cleaning company take care of the vent.  
The cooling light will always stay on during the run.  When it is blinking, the heat has stopped and is in the cooling process.
If there is no heating, you have a problem with the high limit switch or something else electrical and needs to be addressed by a qualified LG technician.

Check the vent and make sure it is not plugged with lint. Make sure the vent hose is clear. The light is telling you something blocking the airflow. You might not be able to see it easily.
