I read this genius post

http://appliantology...roubleshooting/

right here on Appliantology.org and determined that my MCU must be the part causing my Whirlpool Duet to fail. Anyway, I pulled the MCU and found a pretty significant burn mark on the back of the board. My question is...is this unit toast and I should toss it or is there a way to salvage it?

 

Thanks for the great site!

Got the replacement MCU plugged in and all seemed to operate properly.  Ran a cycle and noticed that the final spin never gets over about 50-60 rpm. I ran a diagnostic and it spins to full speed. Any suggestions????

You ran a cycle with clothes? Full load? Just a towel to test? Empty?
By the way if it's working in test mode the mcu is fine... it usually means you had an off balance load. Ie trying to test it with 1 towel or rug or something...
It is never a bad thing to leave it to the professionals. Inexperience can lead to more damage or risk of injury. You can always call A&E Factory Service (1-800-905-9505), Sears(1-800-469-4663), or local service man you can trust (servicemagic.com).
