I had "humming but not starting" syndrome on my washer motor. Replaced capacitor, no help. Pump was clear. Put motor on bench with wiring jig and it worked fine!! So that ruled out motor and switch. I finally saw some mention of these series 90's having a weird phenomenon of the red start wire at harness going bad. I had checked continuity before but never between the cap and harness plug. Eureka!!! open circuit despite looking perfect externally. I spliced in a new 4" section of wire and it's good as old!! 99% of experts recommended new motor with my symptoms. Never give up lol
