Arrived at location on 2/11/22 - Found compressor not running when I arrived, Checked all starting components and compressor and all tested to be good, I found that the contactor when I tapped it pulled in and all components came on and were working, I tapped contactor again and it chattered and went off until tapped again, I determined contactor to be bad which I replaced from truck stock, Unit compressor is very hot while running causing unit to come down in temperature slowly, unit condenser is still full of grease, compressor may need to be replaced in the future but condenser coil will also need replaced because of being compacted with grease, unit is working for now at 18 degrees when I left.
