I think the part # TCA38091801 comes with the Compressor and software jig as a kit.
You can get the software jig separately as part number CJT30000002
NOTE:When servicing an LG fridge that will have the compressor replaced with their new Universal Compressor (TCA38091801), control boards manufactured prior to 2014 WILL NOT WORK with the update jig. This means that any fridge made 2013 and prior must have the control board replaced AND reprogrammed with the jig before running the compressor. Failure to do this will result in a dead compressor which must be replaced again.
