Washer motor cuts out at start of spin (Speed Queen/ Amana)

My Speed Queen (Amana) 2-speed washer (15 years old) cuts out at the beginning of the spin cycle. It starts to spin the tub and then quits. After a wait of several minutes the motor will try again. If the machine is turned off to allow a complete cool down, the intermittent spin recurs when turned back on. I replaced the worn out belts and the pump (bad bearing). I also replaced the timer. In this model the spin cycle starts with a full tub of water so the motor has to grunt to spin all that mass. There is no clutch to allow pump-out before the spin. The motor reverses to spin and this activates the pump-out. Agitating seems normal. The brake works fine. When moving the belt by hand the tub can be spun easily (when empty).
It seems to me that the most likely culprits are the motor switch that switches off the start winding or the thermal protection switch. The centrifugal activator of the motor switch oves freely and can be seen to move when the motor starts. I suppose the switch could be damaged inside though. What about the thermal protector? Can it be replaced? Is the thermal protector built in to the motor or is it part of the motor switch? It looks easy to replace the motor switch. Is belt tension an issue? There is limited adjustment of tension and the belt has a spring loaded idler pulley anyway. Thanks for your thoughts. Milt

Have you checked the cut-off switch that is usually activated by the lid. Maybe it has a loose connection and when the spinning and vibration start, it cuts out? just a thought.

Thanks SkyBlue, the lid switch seems OK.

It more than likely is the motor.

Just a guess, but most washers have an out-of-balance switch which activates during the spin cycle. That might be faulty - worth checking.

Distinct possibility, saw this several times on Amana washers when I was "in the trade". Word of warning, that assembly is part of the lid switch and from memory, ins in about six separate pieces - changing it out is NOT for those of a nervous disposition :-(

In an attempt to fix this problem or did the problem only occur after that?
Did you install a plain rubber belt or the correct one for your model from an appliance parts supplier??
Many washers use a 'low friction' belt which is suppose to slip at the start of a spin cycle which acts as a clutch. If you've installed a plain rubber belt in place of one of those, you are likely putting too much strain on the motor during the spin. That would cause excessive amperage draw, overheating of the motor and likely it to cut out on the motor's internal overload protector.

On Speed Queen clothes washer models without a mechanical clutch, a low friction belt acts as one. Such a belt *must be* replaced with the proper one designed for that washer model and not just a plain rubber automotive type belt!

I also replaced the timer. In this
