Check each screw on your compressor to ground (compressor case). Should be very high resistance Then check the resistance across your teminals on the compressor to be sure it is not shorted. Then check the wiring to your capacitor (The big one). I ran across this just last week. The mechanic didnt have the capicator wired correctly. If it is brand new it will have a wiring schematic somewhere on it.
Dont leave the compressor on very long, but turn it on long enough to get a voltage reading across the terminals. I assume it should be 240 volts. If you have check all of this, they make a jump start gadget to start a stuck compressor. They sell it just about everywhere. Let me know how this comes out..

I don't think you can turn of the beep. Not without tearing it apart and removing the internal speaker, is it really that important? The temp sensor is in the unit.

Check the disconnect switch and make sure that both the fuses are good and not shot. If one is shot then the system wont work. There are two fuse. Also be careful due to you will be working around 210 volts

Contact a qualified service technician and have them replace this sensor.

65 psi is the ideal pressure remember its not exceede from this pressure.
and it is valid for all season
