Put more freon, so that the high-pressure sensor going to close and your compressor will run.
No A/C system holds 80 lbs . or are you talking about static pressure , Looking at manifold gauges . How do you know that's low , if the system is running ? The compressor isn't kicking in ?

needs looking at because it could be switch that allows it to turn on if sufficient gas is present ,or a problem with the clima compùter ,but to do anything you will need the special machine to empty the system then check things out so take to an authorised AC garage ,because these systems are a potential accident and you could lose a finger with frostbite in a matter of less than 2 seconds .therefore i will not tell you how to look for a soloution because of the dangerous nature of playing with air con

Either the system is still low of freon,or the sensor (one of them)is bad.The sensors are on the high side of the system,liquid line.If you will get on chat,I can help you with this,it will take a while,I will need to know how much freon was added.And what the system is doing,is the ac clutch engaging,etc?Ask for ronicon,when you click on chat with,type my name in,roniecon,with your text,that you are writing .

Did you replace the expansion valve?
Also try adding just a little more freon and see if that makes a difference....is there a sight glass you can view with the system activated to be sure you have it completely air free?
SOURCE: will ac compressor make noise when freon is low.
yes it can. this may mean the death of the compressor is inevitable, has been filled with the wrong refrigerant/lubricant, or it is low on refrigerant. you have to determine what type of refrigerant is needed, (usually R12 or R134) and use the correct lubricant, if the refrigerant does not have the lubricant already in it. every time a compressor is filled with refrigerant, it also needs th be filled with lubricant, and most, but not all, commercial refrigerants include lubricant. if there is a leak in your system, you can use soapy water in a spray bottle to find the leaky hose/connection.
