I had a shop check the Freon level and they told me it's perfect. That the compressor isn't getting power. After that it did start working for about 15 minutes and then went back out. What should I do?

Good afternoon,

The first thing I would check is the pressures. I need the high and low side pressures. That is critical in the operation of the system..

When it worked, did it blow cold?

I attached a wiring diagram of the system and we need to do some checks. Do you have a voltmeter or test light for some testing?
