Dometic Duo-Therm Model 57915.622 Fan will not start.

Dometic Duo-Therm Model 57915.622 sounds like it's starting (hum) but the fan never starts. Fan will not operate in any of the "fan only" positions either. Both the fan and run capacitors have been replaced, no help. Fan turns freely also and no smell.
