I know 0 code but we had the same issue and took 4.5 hours to fix it. Try downloading the example compressor code from first and running that- if it works, than you have a code issue. If not, it's electrical.

Our issue turned out to be a combination of electrical and coding. Simple problem is that the pwm from the small blue rectangle box (sorry brain art on the name) to the spike might be plugged in the wrong slot. Also the pwm can be slightly bent in the spike-ours was mangled-like someone got an arm stuck in a blender.

Also, try shorting the circuit while the code is enabled by taking a wire and connecting it to each side of the little sensor that measures when the compressor should turn off. If that makes it work, than your issue is with that little nameless guy.

After trying some of these tests, repost on here with your results.
