I have a Kenmore washing machine (model 110.92273100) that doesn't spin. I've taken the gearbox off, and when I spin the input shaft (motor coupler), it seems to act the way I would expect. When I spin the input shaft one way, the outer output shaft (which attaches to the drum) spins. When I spin the input shaft the other way, the agitator shaft slowly spins back and forth. However, I can hold the output shafts still with my hand, and continue to spin the input shaft.
Does the fact that I can spin the input shaft while holding the output shaft still mean that my gearbox is bad and needs to be replaced, or is it supposed to do that?
Is there a different test that can be done to determine whether or not my gearbox needs to be replaced?
