Motor Getting Hot
I have a fridgire washer thAT WILL WASH and spin very well until the motor gets hot. What could it be ? I openned the motor and the bearing are ok. checked the coils and no sign of coil burned. Motor has only 3 wire. ONE to run forward (washing) and one for reverse( SPIN) a the common Ground. Iknow I can buy a new one or send to repair but that defeact the purpose of this forum . What I really want to know is why the motor is getting too hot after running very well for a minute or two then it shoot it off wait a while and start working. I aready change the capacitor. I will like to know why are the causes regarlees the brand or model. This way I wiil make my how conclusions. Thanks.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Washer motor overheats and cuts out after a short run
- The problem
- A Frigidaire washing machine would wash and spin normally for a minute or two, then the motor became hot and shut down until it cooled. The original poster had already opened the motor, found the bearings apparently OK, saw no obvious burnt coils, and had replaced the capacitor.
- Likely cause
- The strongest supported diagnosis was excessive mechanical load from the drum seizing or not turning freely, causing the motor to overheat. Other suggestions mentioned possible armature/brush faults, a thermal cut-out issue, or heat damage at the motor connector, but these were not confirmed.
- What fixed it
- Recommended action was to check that the drum turned freely and was not partially seized. The discussion also suggested checking armature pad resistance, brush alignment, and whether the motor overheated when run outside the machine, but no completed repair was documented.
- Checks to try
- Motor bearings inspected and reported OK
- Motor coils checked visually with no obvious burn marks
- Capacitor had been replaced
- Advice to check drum turns freely and is not seizing
- Advice to check armature pad resistance and for shorts between adjacent pads
- Advice to check brushes are not bridging two pads
- Advice to inspect wiring/connector for heat damage or blackening
- Parts or tools mentioned
- Capacitor
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Make sure the drum is free too. If it's seizing up for any reason it would cause the motor to overheat.

If you have checked the bearings and they are fine, have you checked the resistance of the armature pads where the brushes touch each side to see if the resistance is the same all the way around, also check the resistance of the armature pads and their neighbours to make sure they are not shorting out, eg nothing conductive between adjacent pads
Also check the brushes are not touching two sets of pads on either side.
Have you run the motor outside the machine and see if it overheats, does it actually get hot! , to confirm it`s not a faulty thermal fuse.
I dont know if any of this will help.
The motor has 3 wire one neutral, one that run forwaq and one that run on rerverse. The electrony board has 2 speed that worked very vell but motor get hot and shut donw when is getting too hot I can not belive is the motor cause is running like new; the bearing are fine (I put the motor apart )I'm use to repair whasher machine en U.S. But in P.R. don not reppair they justtry to sell a new one or a new part. It is make a different a replacea 45uf 250v capacitor with 233- 280 muf 110vac '"b""04-2002
Not sure if it's related, but when my machine motor was getting too hot, I checked the wiring looms. I found black traces around one of the wired which is in the motor connector plug. I hate spade connectors. I trimmed all the wires and connected them using a different means and hey presto, a cooler motor.
