I just replaced the fan motor for the condenser. i was told that to make it restart i would need to reset the high pressure witch to make it turn on.
I can push in the contact and start the unit manually. I was told it was not starting by itself because the high pressure was triggreed. I have looked all over the unit for the switch to push it back in. Any suggestions on where this switch is located?

What's probably happened is that your outdoor unit has overheated due to a high pressure/high temp situation. The reset button at the base of the o.d. unit is a HIGH PRESSURE RESET. This safety is factory installed to prevent the unit from operating under an excessive(per design) pressure.
•The o.d. coil needs to be cleaned
•The o.d. fan motor needs to be replaced
•The run capacitor(s) at the o.d. unit need to be replaced
•There is a restriction in the refrigerant cycle
Its also possible that a component has faulted, along with a high pressure issue. 1 problem can cause another. The reset opening sometimes let's us know something is wrong and its time to repair the problem before it gets worse. Its hard to say what to do now. If it was still opening the pressure switch you could try washing the o.d. coil. Call a tech!
you need to replace your condensing fan motor. the noise you are hearing is the compressor working against a lot of pressure because the heat is building up in you condensing unit. Prolonged operation without an operating condensing fan motor will cause your compressor to burn up, and then you will have the cost of a compressor changeout to the cost of a condensing fan motor.
Either the condenser fan has bad bearings, or it has a defective fan capacitor.
Turn off the breaker to the outside unit.
Spin the fan blade by hand.
If the fan blade spins easily and will spin a few revolutions with no problem the fan bearings are good.
If not, replace the fan motor due to bad bearings.
I am pretty sure you fan motor is bad because with a bad capacitor the fan motor will not get up to speed and may just sit and overheat.
I'm leaning toward a bad fan motor.
Condenser coil is dust blocked.-Clean it. Rpm of fan motor is less-Replace capacitor. If over charged gas- release some gas. Check for continuity for high pressure switch, if no continuity, replace high pressure switch. Thanks.
E3 Outdoor activation of high pressure switch due to over charged gas. and also due to less rpm of outdoor fan motor. High pressure due to non condensable gas. Remove all gas and flush out. Then vacumize and gas charge. If motor less rpm, replace capacitor or fan motor.
Is the condenser fan (outside) turning? You mention that it's hot but don't say if it's turning or not.
These fan motors normally run pretty hot, but not so much that they shut down due to internal thermal overload protectors.
Both the compressor and the fan have termperature overload protectors to keep them from burning out the motor in the event of an overheated condition. The condenser fan must be running or high freon pressure will put an excessive load on the compressor and it will 'kick out' the high-temp overload protector.
Turn off the unit by pulling the outside disconnect (in a small box near the outside compressor unit) or flip the AC breakers in the breaker box. Wait about 30 minutes for the unit to cool off and turn it back on. If the compressor and fan both run for awhile then kick back off, or the fan motor seems to be working under excessive strain, you've probably got a bad motor start condenser (inside the unit) that little round can that is connected through the fan motor wiring. If it's swollen or leaking, it's almost surely defective and even if it's not, excessive load on the motor is a classic sign of a bad start condenser.
You can usually find these at electrical supply stores, well-stocked hardware stores, or most certainly at an HVAC parts house. Be sure to replace the old one with one of the EXACT same value (in voltage and Microfarads (mF) capacity. The shape may be a little different, but as long as the electrical characteristics are the same and is rated at the same or higher voltage than the original, it will work.
Connect the new condenser, mount it to the frame, and restart the unit. This should take care of the problem.
