Hello,

Is there a way to run a test using an multimeter to check a washer motor and a dryer motor. Are there certain levels that the motor should test for to indicate a healthy motor?

Also, are there any good video tutorials out there which would help with visual instruction?

Thanks

Dryer Motors are only one speed, so then you could usually just apply 120v AC to the Run windings,
but before you do that, try turning the Motor Shaft by hand.
Does it turn easily smoothly ?
Can be "spun" and the Shaft continues to turn somewhat ?

Washer Motors are more complex and may be one speed or up to 3 or 4 speeds.
But the Run windings are separate from the Start winding and would need to be powered, also.
Polarity of the Start winding determines Motor direction.

You could just do an OHM meter check of either Motor, but that's not a guaranteed test.

The motor shaft turns fine on both the washer and dryer motor. The dryer sounds a bit scratchy but I think that is just lint. Otherwise it spins fine.

How do you apply the 120V AC to the run windings? And what would I be looking for after that?

Also, how would you run the OHM meter check?

Thanks

Dryer 120v to Run windings.. depends on Dryer or Motor model number.
If powered-up correctly, it should "run", but not a definite test unless you'd let it run for a few hours, and may also need a (torque) load
OHMs may be anywhere for 1 to 4 OHMs

Depending on model, some front-load Washers use a 3-phase Motor & Controller
