Product review (2 stars): WH01X10310 GE Washer Control Knob Assembly
This washer control knob assembly is not the same size as the one it replaces.  The stem is a little longer and the machine will not start just by pulling the knob out like the old one did.  This one needs to be turned till its put on the correct setting.  You can get the machine to work this way but its definitely not the same.
