I can't figure it out. I keep having to let refrigerant out
of my Adler Barbour. It runs great with the suction-side
pressure set at 15 psi. But, every month or so it will
commence to cycle off and on after being off for the night.

I put a gauge on it and the suction side pressure is in the
beginning of the red range(55 psi). It turns on and the
compressor starts compressing, the pressure starts going
down but it only gets to about 45 psi until the compressor
*clicks off* and the voltage gauge goes up a volt or two
because the load comes off the circuit.

Then it turns itself off and back on and the compressor
starts to compress again and the pressure goes down to about
45 psi, then it cycles off again.

So, I let out some pressure until it only starts out around
45 psi and it will finally keep compressing until it draws
down the suction side to about 15 psi where it stabilizes.

So where does the extra pressure come from. I've had to
let out ten pounds of pressure about half a dozen times
this summer. I can understand leaks but this is ridiculous!

You have a closed system connected to a compressor. One side to the
suction side and the other to the pressure side. Think why the suction
side would be at a higher pressure, or conversely, why the low
pressure side is at a lower pressure in a properly operating system.
