Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am APPLIANCE-HVAC GURU a very experienced tech on here and I try to get to as many customers as I can. I just picked up your question now.

Please allow time for me to respond, sometimes I get the questions or responses late so please be patient as I have no control over the site issues. NOTE, I have nothing to do with your payment to the site and did not receive that money.

Answer:

Typically when that happens the speed sensor is dirty or failing. That tells the board the speed of the motor and if it is not working right it will have pause the motor longer before going in the opposite direction. It is part #911 at this link.

Let me give you a little more info I found.. I put my meter on the capacitor while it tries to agitate and I get 150 volts when it goes in one direction and some times I get as low as 5 volts when it tries to go in the opposite direccion those 5 volts will vary some times it will be 150 ,130,50,70 does this support the speed sensor failure???? Just asking because I want to have a little more certainty before I order the part
Customer: replied 1 year ago.
not only pauses the motor it also seems like it does not have enough force to agitate, it barely moves

Have you checked the motor windings with a ohm meter to see what they read?

Customer: replied 1 year ago.
they both read 6 ohms but I don't know what they should be at

Please watch this video I removed the cover and recorded the way it agitates
Expert:  Appliance Guru replied 1 year ago.

If you are getting that low of power to the winding when it rotates you either have a bad capacitor or a bad control board. I would change out the capacitor watching the video it looks like a failed capacitor.

Customer: replied 1 year ago.
The original capacitor is a 45 micro farad and I swapped it with a 48 micro that I had and it did the same do you think the difference in capacity will matter, some Body told me that the problem could be the tub bearing but that did not made sense to me. What do you think is there any chance that a bearing will cause that?.. Is there a way to check the board??

If you take the belt off does it rotate fast?

Customer: replied 1 year ago.
it does
Expert:  Appliance Guru replied 1 year ago.

Does the center pulley spin freely by hand it should, if it is bound up that could be the issue.

This one shows the motor with no belt
Customer: replied 1 year ago.
What do you think should I go ahead and order the speed sensor??? Or should I check the board some how?
Expert:  Appliance Guru replied 1 year ago.

I would try the speed sensor

Customer: replied 1 year ago.
OK I will order it and see what happens
Expert:  Appliance Guru replied 1 year ago.

ok sound good

Customer: replied 1 year ago.
OK so I got the speed sensor today I changed it but it made no difference, I found this diagram that came with the machine it says that the windings should be at 4 ohms I checked mine and both are at 6 ohms
Customer: replied 1 year ago.
Do you see something else on the diagram that I should test???
Customer: replied 1 year ago.

The 6 ohms should be ok so this basically leaves the board as the only thing
