LG dryer won't stop running

[boardslide]

Hello all, I've been searching and searching but have not been able to find anyone posting with this issue.  My LG DLE2516W works, but won't stop spinning after it's done.  The only way to make it stop is to open the door and/or unplug it.  The display will count all the way down and then turn off and the heat will stop, but the drum will continue to spin.  The moment I close the door it will start to spin again, and if I push the power button the display will turn on and I can select a program.  If I press the start button it will begin to heat and work like normal until it's done and the display turns off yet the drum is still spinning.
 

I cleaned out the lint and the moisture sensors.  Running the diagnostics the moisture sensors will count up to 255 and the temperature will go up if I let the heater test run.

Any ideas?  TIA...

Most likely cause is the motor relay is stuck on the main control board.

Id have to agree with scrapiron. It's a main pcb fault in the relay: either stuck points or shorted relay circuitry holding the relay closed.

Thanks guys.  Manual didnt show much in the way of motor relays or switches so I'll start here.  PCB on the way.

Just an update for future searches, it was indeed the main PCB.   . Very easy to replace.

Thanks!!!

Good to know, thanks for the update.

I've had this same problem. I'm not a technician, but savvy with general handyman type jobs. Is this a part I could order and replace myself? Thanks for the help!

Great, thanks so much for the help!

Is this something I can reasonable do myself? Any tips for getting to the control board? Anything else I should try before buying this part? I already cleaned the lint trap and sensors as people on other forums suggested and that didn't fix the problem.

This is for a gas dryer, but disassembly is IDENTICAL. You only need to watch up to 1 minute and 30 seconds or so. The main PCB is mounted to the display PCB on the rear of the control panel...

Hey everyone,  I just got a call on a 14 month old Kenmore electric dryer (made by LG) with the same exact problem.  The motor won't shut off but you can run the cycle by powering up the board, selecting a cycle and pressing start but it won't shut off without opening the door or unplugging it.  I guess I will order and replace the board.  Thanks!!!
