WC pro 55 jamming in inverter section

[nmfaxman]

I noticed the inverter motor is chattering when trying to reverse.

I found a whole inverter unit online and need to know if the motor is a part of the inverter or the duplex unit.

First one of these I have worked on and don't want to order the wrong unit.

Thanks for any info.

First check inverter drive PWB.
