When turned on fan comes on when you lower thermostat to turn on the cold air nothing happens

are both your fans coming on but not the compressor? if so maybe your compressor needs a power boost attached to your capacitor to help jump start the compressor,

I hav a miller p3rd-030k when i turn the thermostat on fan comes on but not the compressor

Could be the compressor leads burned off the terminals at the compressor, or contactor switch is bad, or capacitor is bad, or compressor locked up.If you can use a multimeter you can find the problem. If not call a service man.

Any capacitor of the same rating as old one will work, it doesn't have to be a Intertherm part. I would say its 25-35 ufd 370v.

Compressor will not stay on.

very good possibility that it is low on freon. If indoor unit is blowing ambient air, not cooling is happening. If this is the case and you are sure the compressor is running and then shutting off, the compressor could be overheating and the internal overload is taking out the compressor. If outdoor fan runs and compressor runs, probably cause. If capacitor is bad, unit would most likely not run that long. While unit is running, feel the large line at the condensing unit. If it is cold, and stays cold, could be something else going on. If stays warm, most likely low on freon.

Need copy of the wiring diagram

I am sure there is one to download. If google is no help, just ask some deep web specialists, e.g. - this is a manual search agency and if they don´t find it, it does not exist in the Internet.
