Check your warranty. Should be covered for 1 year.

take it back its still under warranty dont pay to fix it

You may need to do some cleaning:



To the right of my hand is your tripped limit. It is the second most replaced part besides a heater element.

I have a service manual and more here

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.

half of the heater coil bad

Hi


Thanks for using FixYa. The first thing that should be checked is the Thermal fuse which is mounted to the exhaust duct inside the back cover. If this fuse goes bad the dryer will not heat and you’ll have to replace it as it cannot be repaired. If this I fine then you’ll need to check the thermostat, igniter and coils. Also as its only 3 months old so it is recommended to use the warranty to avoid any further issues. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

That oil is transmission oil. Not to worry there will be lots left inside

Clean off the moisture sensor bars. They are the silver curved strips about 4 inches long inside the drum near the lint fitler. If you use fabric softner sheets, a waxy build up will coat the bars. The dyer can no longer sense the damp clothes, so it goes into the cool down and then shuts off. Time dry bypasses the moisture sensor.

This is some basic info I could find on your dryer. I will need you Serial Number in order to determine the year it was produced. Please post back with comments and let me know.
