Product review (5 stars): GE Harmony WPGT9350C0WW fixed using this part
I used this part to replace a  6501KW2001A sensor on a GE Harmony WPGT9350 series washer. LG supplies the components to GE for this washer. The error code generated was that the motor was not turning properly and this sensor is a common cause of that error. It is easy to troubleshoot the sensor with a voltmeter and is pretty easy to replace. GE parts was asking $76 delivered for this sensor and I got it here for less than $20 delivered.

It takes longer to unhook the hoses and lay the machine on it's side to access this sensor than it did to replace. You will need a 24 mm socket and 10 mm socket to remove the stator and then you can swap out this sensor. You can find the GE service manual online that details the trouble shooting process.
