My AC unit outsides keeps shutting off every 20 to 30

Customer Question

Hi...My AC unit outsides keeps shutting off every 20 to 30 seconds. I had a guy come out and of course it didn't happen when he was here. It looks like it has to be running for awhile and then it starts doing it and doesn't stop.

I hate when that happens.Hard to diagnose when not acting up.Let me ask a few questions.

1.Do you happen to have gauges so we can watch pressures?

2.Does indoor continue running

3.Does both compressor and fan stop at same time in outdoor unit?

1. No 2. Not sure it happens every 30 seconds so hard to tell, sounds like upstairs it stays on 3. Not sure what that meansI'm sending a short video... this is what happens over and over
