LG WM-3677HW dryer cycle does not dry and lasts for 3 minutes

Check the heating element for continuity. Here is the part if you find it bad.

You have a restricted exhaust vent in the house and needs to be professionally cleaned.

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.
***************************************************************
Hold down on the 'More Time' and 'Less Time' buttons and press the 'Power' button. if it comes up with tE1 or tE2 you have a thermistor error.

Clean off the two metal bar inside the drum, near the lint filter. (these are the moisture sensors, which can become coated with fabric softener sheet residue, preventing the dryer from "seeing" that the clothes are still wet)

make sure there is power getting to the pump if so then your pump has stopped working or may be blocked if not than it will most likly be your pcb

CD means cool down, press the pause start button, the door lock will open. It is an anti crease cycle. It mentions it in the owners manual, but it is hidden deep in the drying section.
