Hello Guru,

I have a Kenmore Front Load washer, model number 417.40042990. Speed control board 131770700.
The drum will no longer spin. I have gone through all of the technician trouble shooting and all systems pass.
I can manually forward the machine through a cycle, it fills and drains correctly, just won't spin in any cycle. Reading blogs it seems like the speed board is the most likely culprit, but it passes voltage, resistance, and fuse test. Is there anything else that it could be other than the speed board?

Thanks!

_{Drum/motor does not move at all, tumble or spin. Thanks for the new diagram, I am not sure if I tested pins 5 to 1&9. I will try tonight.
I did inspect the speed control board thoroughly and did not see any damaged or heat affected components, of course one of the IC's could have fried on the inside.
Anything else I should try tonight?}

Rogdog, if I may ask, what browser type and version were you using when you made your last post? And was it the same as for your opening post?

Reason I ask is that we're randomly seeing the occasional post in the x2 ^superscript or x2 _subscript. For example, your last post is shown written in x2 ^superscript. So we're trying to track down this bug, whether it's in this forum software or with just a particular type of browser (brand and version).

Domo for your help!

Same system as original post.

The two most common no-spin makers on this machine are the motor control board and the door latch. The troubleshooting procedure can be tricky to follow, but if you're not getting an error code, chances are pretty good that the problem is the motor control board ==> http://www.repaircli...er=417.40042990

But the good news is that you're not really taking a chance at all! If, by some freak of nature, the motor control board doesn't fix the problem, return it for a refund!

This might sound dumb but check the belt first .. They rarely break but I always check that first... If it does everything but motor doesnt move more then likely motor control

Check the wire harness from the speed control board to the motor...the last wire restraint mounted to the floor near the motor is known to pull the terminal loose and/or pull a wire out of a terminal at the motor.......

Appliance Guru!

Thanks for the rapid advice and additional trouble shooting diagram.
With Repair Clinics wonderful return policy on electronics, I purchased the speed control board with conficence.
Five minutes after arrival, it was in the washer and the washer ran like a champ.
Thank you for everything, you run a great service here!
