I was doing an AC maintenance and ran into this packaged AC not cooling. Found the compressor not running and windings open. The air conditioners compressor was extremely hot. I return the following day to see if windings closed. Also troubleshoot the faulty compressor.
When I approached the air conditioner, first thing I did was turn on the power at disconnect. I heard the compressor start up and run. I noticed the suction line was warm. I checked pressures and they were about equal. The compressor didn’t sound good. I changed the power/ phase into the units contactor, to see if the compressor was running out of phase. After this the compressor started pumping correctly. The compressor was out of phase. After the video I cleaned the condenser coil.
