Kenmore 70 washer intermittently stops spinning

It sounds like the problem may be related to the washer's lid switch. The lid switch is a safety feature that prevents the washer from spinning if the lid is open. If the switch is malfunctioning, it could cause the intermittent spinning issue you're experiencing.

Although you mentioned that the problem occurs in the middle of a cycle without touching the lid, it's possible that the switch is still the culprit. The lid switch may be loose or worn out, causing it to intermittently lose contact and prevent the washer from spinning.

You may want to try testing the lid switch by manually activating it while the washer is running. You can do this by opening the lid and using a small object to depress the switch. If the washer starts spinning, then the lid switch is likely the problem.

If the lid switch is indeed the problem, you can replace it relatively easily and inexpensively. However, if the issue persists even after replacing the lid switch, it may be time to call in a professional for further diagnosis and repair.

If by gently tapping the timer it starts to spin, perhaps it may be a dirty contact inside the timer.

Do not try opening it up to fix it as you will have contacts and cams everywhere.

There are about 12 cams and 24 contacts inside the timer arranged like a clockwork mechanism.

With the power disconnected from the machine try liberally spraying some electronic contact cleaner (example only - do not use regular WD40) through any openings in the timer, allow it to fully dry (read the label on the can), reconnect the power to the machine and check if it works OK and is not intermittent.

If still no good then if you determine that it is the timer, search online for WP66149 (examples only) to find suppliers that suit you best.
