Equalized 100 seems a bit high but high ambient i could see that happening.

Code reader will show if pressure switch is not reading. Foxwell will command compressor on regardless of conditions normally preventing like fan not working or pressure low.

That's the easiest way to test. Force compressor on with foxwell or a jumper and see if you get cold on the low pressure line.
