Today our Duet Dryer runs anytime the door is closed even if the dryer isn't "on" according to the front panel. The only way to get it to stop is to either open the door or interrupt power at the breaker. It is not warm, it's just spinning. While it's spinning with the door closed and "off" I can turn it on with the power button on the front panel, select a cycle and run it at which point it runs normally with heat, the cycle ends according to the display, but then doesn't stop spinning.

What can I do to fix this? How can I verify the root cause of the issue?

Thanks!

I think the relay on the main board is stuck. You will have to replace the main board. I am not sure exactly how to tell you a test to confirm but I would think that's what it is.

Hi Brian, Yes Shawn is correct.

This is the part you will need to replace on yours:
WPW10174745 Electronic Control Board


These are the terminals that makes the motor run--->Motor P9-1(light blue wire) and MTR CS P8-5(black/white wire) on the Electronic Control Board.

Here's the tech. data sheet that shows you that too.

Thank you both! What I'm first going to try to do is to replace the stuck relay on the existing board and if that doesn't work then I'll replace the entire board. I'll let you know how it goes.

I looked at the board, and indeed look at this big burned mark on one of the main relays! I ordered a replacement relay; it's an Omron G8P-1A4P-ACD.

Yes, I see that. That's the problem!

Let us know how it goes.

It worked! After some de-soldering braid and solder sucker use, the relay came out pretty easily. The new one fit great. Check out some pics along the way.

Thank you all for the great advice!

Excellent, good job.

Thanks for the update!
