Carrier air cooled unit

Condenser fan runs fine and then goes off when compressors kick in

Can't get both to run together

Off course compressors will also stop on thermal shutoff I guess

Any ideas what's up

Changed freon filters both compressors c 164 s

Freon cked again after 164 installed today

Thanks

History?

Let's say this was a new install with the same lines and suppose some dirt or a bug crawled into the line because it wasn't capped. So, I'm suggesting it's cutting out on one of the pressure switches.

Reason could be debris or incompatible oils. Need history.

Not sure if that info is available at the Infinity Stat or if your outside unit uses the ABCD bus. If you have both, then the info is likely in the error logs of the Infinity control.

Otherwise, do the troubleshooting the hard way.
