My LG DLE4870W dryer would not stop running. The only way to stop the dryer from turning was to i'ther open the door or unplug it. As soon as I would plug it in, it would start running again. Called LG customer service and that was just a waste of time. Called a service repair man and they wanted $90 to come look at it. The guy I spoke too even stated that it would probably be better to purchase a new dryer than to have them repair it. He also stated that the problem was probably the PCB board and it cost $195 and it would cost $179 to install it. So $90 + $195 + $179 = $464 (plus taxes). After doing some research on the internet, I determined that he was probably correct and the most likely cause was a stuck breaker in the control panel. I found the part on AppliancePartsPros for approx $160. Considering my dryer was not even 2 years old, I was a bit nervous about taking it apart, but it was actually very easy. I only needed a phillips and a flat screw driver. I also would like to note that the customer service of AppliancePartsPros was very helpful, not only in helping me order the right part, but they were also able to tell me where the part was located within the dryer. There seems to be a bunch of different problems related to this board going bad including Dryer not starting and dryer not heating. Don't be afraid to tackle this yourself, thanks to AppliancePartsPros and youtube, repairs are easy. I also made a repair video and added it to my youtube channel. Good luck!
