Try a timed dry cycle instead of an automatic cycle. If that works, then you will need to clean off the moisture detection bars inside the dryer to get the auto cycle to work again. Look for two curved metal bars, about 3/16 inch wide and 4 inches long, about an inch apart, located just inside the front of the dryer, near the right side of the lint filter. (you'll have to stick your head in the dryer drum to see them) Often times, use of dryer sheets will result in a waxy coating forming on these bars, preventing the dryer from detecting the moisture in the clothes. The dryer sees no moisture, it goes into the cool down mode and then stops. Clean the bars off, and you should be back in the laundry business.

you can't get any parts for this dryer the computer board is no longer available,must be old technology replace it.

AD is auto dry you may need to clean the sensor or you may have a fauilty one ...Auto Dry Loads dried using the Towels, Heavy Duty, Normal, Perm Press, and Delicates cycles will dry automatically at the selected temperature to the desired dryness level. The dryer uses sensing bars to sense the moisture level of the load as it tumbles through heated air. Auto Dry cycles save time and energy and protect fabrics. The estimated drying time will be displayed for about 5 minutes, then the outside of the display will light up in a circular track to indicate the drying time is automatically being determined by the sensors. When the load has reached the selected dryness level, it will continue to tumble, unheated, during a Cool Down period. This helps reduce wrinkling and makes items easier to handle during unloading. The estimated Cool Down time will be displayed. Drying time varies depending on size and dampness of load and fabric type. If the load is too small or almost dry, the sensing bars may not detect enough moisture to continue the cycle and the cycle may end after a few minutes. Select a Timed Dry setting to dry such loads. Room temperature and humidity, type of installation and electrical voltage or gas pressure can also affect drying time. For cycle selection turn the knob on the front of the dryer control panel. The light will illuminate next to the cycle selected. The following is a brief description for what cycles should be chosen for certain items and materials to be dried.

Check the timer, and the sensor. Sounds like it is having a problem with the timer or sensor no noticing that the clothes are still wet. Please rate if satisfied. Thank you

Call the mfr and ask them about it. This problem may be pretty complicated. There may be a problem with your board that tells it to go to cool down. Can you set the timer for 45-60 minutes and it stay on heat for that long?

Try cleaning off the two curved metal bars (about 4 inches long) on the inside near the lint filter. They are what senses the moisture on automatic dry. When you use fabric softener sheets, the stuff from the fabric softener sheets can coat the bars, which makes the dryer think the clothes are already dry, and puts the dryer into cool down. (using time dry will also take the moisture sensor out of the cycle, if you'd like) This should be a Fix-Ya for your problem.

Shelly on some of the older models they used a inline resistor on the dryers timer. It looks like a inline fuse comming off the timer. If it goes bad the timer will not stop. Check the attachment. Cost around 17.00, Catriver, post back. Part number 3401076

I'm sorry to hear of your problem with your LG dryer. I have one as well and it works very well. I found my owners manual. It has a web site WWW.LGSERVICE.com. They also have a toll free number 1-877-714-7486. Perhaps either of these will help you find an answer. Good Luck
