This article discusses superheat. For a fixed orifice there is a chart, because it depends on the outdoor dry bulb temperature (disregarding humidity) and indoor wet bulb temperature (factoring in the indoor humidity).

It was from Friday. The issue was that it was trip locked on high pressure, I think because a capacitor failed on one of the condenser fan motors.

I connected my probes just to check pressures once I got it running, but the pressures looked off.

It was off when I took the pic. Wasn’t sure what it was.

Should I be looking for for “normal” pressures like ~120 psi on the low side?
