Cx complaint unit intermittantly loses cooling. Was able to access unit and found 39F in RC and 6F in FC but FC had no items. Removed evap cover and found good frost pattern and unit began a defrost. Verified compressor and all fans and damper operation. During test 4 compressor is loud and clicks off. Ohmed out and found 10.6 Ohms 6.4 Ohms and 17 Ohms. At time of visit unit is operating and cx will need to monitor and call back if issue returns. Collected for service only
