I had a new compressor installed 4 months ago. Everything was fine until a few weeks ago. They AC started cycling. Worked ok for 10 seconds, shut itself off for 10 seconds etc.. Now it goes off almost the instant I turn it on. I'm going to bring it back to the shop that put in the compressor. Any idea what's wrong with it ? I'm thinking one of the temp sensors ? The external temp sensor has been flaky for a while. Often times it will show 75 degrees when I know the real outside temp is ~100. But from what I've read, the AC only shuts itself off if it detects the outside air is below freezing.

It sounds like you may have a small leak in the system. Have you checked the charge in the system? Just a thought.

Compressor won't run if refrigerant pressure is low/zero.
