Why doesn't my rockworth compressor fill up when it's running it's brand new

This could be an assembly error at the company. There are three valves in a compressor, one is an intake, one is an exhaust, one is an unloader. The easiest way to check is to put your hand on the intake air filter to check for suction. If there is suction then the valve is ok on the intake, if it flutters then it is bad or missing. Locate the on off switch and there should be a valve that unloads the pressure from the compressor, see if that is leaking.

Just bought a campbellhausfeld fl3307 compressor at an auction did not realize that it has mc94 2 hp moter which is wired for 230volts but my garage is not On the compressor it says engine can run on 120...

The wiring diagram to change the voltage is on the name plate on the motor. The motor leads are numbered. Go by the diagram and reconnect the numbered leads the way it says for 'low voltage'

Air conditioner does not work. I turn it on and it tries to start, will not start, turns off. When I turn the thermostat off you can hear a click back by the A/C unit. This is on an 03 Weekend Warrior...

the click you hear is possibly the contactor switch on the unit. This swith is activated by the thermostat which in turn sends voltage to the compressor. First things first, You need to check the contactor swith to insure you are getting power from the switch on.. Activate the thermostat the contactor will activate you shoud get the same voltage reading from l-1 and l-2 as you get from the t-1 t-2 sides of the contactor. if these readings carry the same volts then your problem is towards the compressor. Next item to check is the capacitor. this is a round or oval shaped metal cylinder that has several wires going to it, Some of these capacitors are dual, in other words they run both compressor and condensator fan motor in one unit sometimes each peice , compressor, fan motor, has a seperate capacitors If it is a dual capacitor the will be 4 or more wires going to it. since these aren't as costly I would recommend that you replace the capacitor and see if that has cured your problem., If it hasn't then you are possibly looking at a bad compressor and an a/c tech would need to be called to check that for you. Good Luck
