Hi Carl, what was the outside temperature when this happened? Also, the condenser fan should come on as soon as the A/C is turned on. Did that happen?
The idea that the low pressure went down when the fan was on could make sense because the temperature under the hood changed. But the high pressure is certainly too high. Even at 110 degrees F, I wouldn't expect it to exceed 345 PSI.
Let me know what the outside temperature was and if any other parts were replaced.
