You might look at it that way, but that figure alone is rather meaningless to me. Just like a low suction pressure by itself doesn't necessarily mean under charge.
You got us going, clean the coil with a water hose with the power off, run the unit for awhile so it stabilizes and then put your guages and thermometer to work and report the results. You are willing to learn, right?
I will go back later this week and get more information, also to clean the coil.I have to admit I don't have hardly any test instruments,I have a Fieldpiece with a tempature readout, I'm sure this is fairly accurate ?I will read the amps, pressure etc.
Are you checking temps with the unit doors on? If you have the doors off it will really effect the high side pressure as the condensor will not be drawing air over the coils. Also I don't care how you do it or whether you think it needs it or not, clean the condensor coils. I have seen amazing pressure changes after cleaning coils that I could have sworn were clean.
