Product review (3 stars): Instructions unclear.
It is necessary to re-wire the hookups.  There are instructions included with the motor but the codings are different and I have not figured out yet how to plug them in.  The old switch has a panel with six colored dots on it.  The new one has numbered blade connectors, about nine in all, and three of the wire ends need to be replaced with the included 1/8" ones.  I'm still thinking and may have to get professional help. This same motor fits many(!) different models and brands of dryers.
