My AC is working fine, almost. The AC Unit starts up, all is well but after about an hour or so the Outside condensor fan stops running. It is still cooling just fine. I checked the capacitor, and they appear to be fine.
Historically, I have had the capacitors replaced once, and one the wires on the connector panel has burnt of 3 times. It is about 4 years old.

Communication problem. You say condenser stat and power are fine? if that means the condenser runs but the air handler doesn't that means the communication is good and the blower is not running. That may be a capacitor (you must have ammeter capable of checking microfarads) if not that check power it may be board driven. If no power to blower the board is bad assuming power is at board. If that is ok the blower motor is bad.
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.
This model of Goodman A/C the condenser coil get extremely dirty and what happens is when your condenser runs for a long period of time it pops the capacitor. This is the starting component for the compressor and the fan outside. the coil needs to be cleaned with a non acid condenser cleaner. Open up the side compartment of A/C look at the silver cylinder thats the capacitor if is looks swelled replace it.
Turn off power, if this is a complete outdoor unit, remove the blower door Turn Unit back on see if the blower motor is working. If belt driven belt is loose or off, if direct drive and the fan is not working, its possible the capacitor is bad or fan is bad.
If fan is operating, then either a damper is closed, something is obstructing the duct or it is at to low
first disconnect the green stat wire wire could be bad if still runs change the board on the indoor unit pull board and take to goodman store with model number and serial number its under warrenty they will give new one hope this helps also look at dip switches and instructions to make sure ok
Many outside AC units have just one capacitor that starts the compressor and the fan. Some units however have two. Just follow the wires from the motor to the capacitor, pull it and test it. Make sure you disconnect the power from the unit by pulling the fuse block first. If the capacitor is good the motor may have siezed up or burned out.
I believe you have 1 of 2 problems going on here your system may be overcharged causing the compressor to cut out on a overload relay circuit internally, or it also could be tripping out a high pressure switch which could be from an overcharged system or a dirty condenser. I would have the tech come out on a 90 degree day and put the gauges on and check the pressures while it is operating under a full load.
Whats the amp breaker? Is this for the inside unit or the outside condenser? If the inside and gas heat you have a bad fan motor, If its an electric furnace , the same, but if its the outside unit, the fan could be going bad, locking up and the compressor still runs and pulls high ampsand tripps breaker or the compressor is just pulling too many amps due to plugged coils with dirt , grass or weeds blocking airflow.(firstname.lastname@example.org)
