My Speed Queen Top Loader heavy duty washer is from around 1988. It has long worked well, but now has problems. First it stopped completing tha wash cycle, halting in the soak cycle. Turning the knob a little would cause it to resume. Now it is even more off - Last time I started the machine it immediately began the spin cycle. I stopped that, turned the control knob and restarted. The full cycle began, completed, and then restarted again. There is something wrong with the controller. I opened it up but the closest thing to a part number is RSFC 29966. Thanks for any help.

First unplug the machine, now take off the front panel, two screws at the bottom of the front panel, front panel swings up and off.

check to make sure the six springs are still in place.

Under the tub is bearing housing between the tub and base usually white in color, under this is a plastic ring, does it seem to float easily when you move the tub. it could be broken. Also look around for loose or missing screws.

If all seems fine, make sure you have all four rubber feet on, level machine, in the front first side to side, then pull machine toward you to bring rear legs off floor, these are self leveling, have someone assist and make sure they are not stuck, use a pliers and break loose if they are. So with the machine on its front feet and the back feet off the ground set the machine down on all four feet check level front to back adjust as needed on the front legs. You should reset rear legs as you adjust the front. now with machine level tight the nut between the front legs and the base locking them.

This should help, if machine still shakes it could be the balance ring, has lost if solution its filled with a salt water solution, the hard part is you need to find it under the tub cover. we will go into the detail if we need to. ask more questions later
