Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
The reason these don't spin fast enough is the motor control board, this machine is actually a Frigidaire even though it says Kenmore, Kenmore doesn't make anything they have other companies make them for this one was made by Frigidaire
here is the information on the spin speed control board,
Spin control board assembly. Front load washing machine
Manufacturer NumberNNN-NN-NNNNyou will need to order and replace that, you will have to order it in Canada because most of the US suppliers do not supply Canada, on average is part runs around $165.00, this is located in the back of the machine in the right hand corner inside, thanks, Bryan
Okay that changes my analogy a little bit on this, this point more towards the timer than the speed control because of this does spin up to speed sometimes than the control board is fine they either work or they don't they never really go up to speed if they're not working correctly, inside the timer there are contacts, the contacts are burnt, they, like points in an old car but you really can't take these apart because you'll never get the timer back together and the points bend and you'll never get them in the right position again so yes you need to replace the timer I'm sorry, actually that's a lot cheaper anyway so that's good it's only around $76.00 let me get you that link, be right back.
