John B for Model Number DLE0442W I have an electric dryer (LG model DLE0442W), about 5 or 6 years old, that will occasionally continue to run, even after the power switch is turned off and all panel lights go out. It will stop when the door is opened. Unplugged the unit for a couple hours, and it starts right back up again when you plug it back in, even with the panel lights still off. This happened about 3 or 4 months ago for the first time, and then again today. So, both times, I plugged it back in again, and, while it was running, went through the motions to start a load of clothes - hit the power button (which turned on the panel lights), then selected the 'Normal' cycle, and then hit the button to start drying. After about a minute, I hit the cycle button again to pause the dryer, and it worked from then on out, as if somehow going through the motions reset the "computer" or something. Power button now turns the unit off, too. And the dryer heat works as well. Trying to determine if the problem is the main PCB? I'm sure it will happen again.
Answer John, While it is possible to have the relay sticking on the control board, you will also want to check the motor to make sure that there is not heavy lint build up around it. If there is then the centrifugal switch could be sticking on the motor. If heavy lint build up then clean it out and if the issue happens again then the control board would be the issue. Read More...
