Arrived on site and checked in with customer verifying complaint. Was directed to reach in ice cream freezer. Unit was unplugged. Opened unit up and tested compressor for direct shorts to ground. No direct shorts to ground. Tested compressor winding insulation with megameter and it was in caution. Tested start components and they seemed to be fine. Attempted to put on hard start 3n1. Unit showed locked rotor amps of 36 amps. Compressor bad.
