I’m a service tech and have been in the business two years. I know my way around most appliances but obviously still learning. I ran into an interesting customer complaint. The motor on his speed queen was humming really loud. The customer told me it was eddy current in the motor and that I needed to replace the motor for him. I’m curious if anyone else has run into this before? The washer still worked fine, spins, agitates drains etc. just the motor is noisy. I wasn’t sure what all to check.

Need to know... The output of the motor control circuit should only put 120VAC on one winding (CCW or CW) at a time? If I measure the output of the control board I seem to get 120VAC on both windings, at the same time.The start capacitor checks good, so I'm thinking the Triac circuitry may have gone bad. It there a way the triac for the motor control can be replaced, instead of the whole control board? Whenever the motor is supposed to drive (spin, agitate) it just hums. As I said, there is 120VAC on both windings at this time. I would assume during spin, it should only have 120VAC on one winding (CW or CCW).... Have run the diagnostics and it keeps saying replace main control board. Seems there is a less expensive way to repair, $220.00 may be more than it is worth....
