Looking for condenser fan mounting

there is a run capacitor is probably bad.
you can purchase a replacement one from slakey brothers. However the capacitor will still have a charge after the power and wires are removed. after turning off the breaker use a long bladed screw driver and ground the electrical leads to discharge the capacitor before removing. take it with you to the supply house along with the model and serial number of the condensing unit.

Ok first thing is it sounds like a wiring problem. So first step is to make sure the thermostat is properly connected. Which... the main thing here is there needs to be 24v dc power coming from your control board (transformer) going to the thermostat..generally that is the red wire. All the thermostat does is connect that "red" wire (power) to one of the other wires to complete a circuit. So make sure you have 24 volts... (generally about .5amps) . if you have power than switch thermostat to fan only should energize the green wire only. then switch to ac and move temp low enough that the ac should turn on and that should energize the yellow wire. for sure one of those wires is incorrect now or the fan wouldn't be on OR THE THERMOSTAT IS NOT CONNECTING THEM AND IT IS BAD. Now about the compressor and fan.... those same wires run out to the compressor unit... ok the yellow for ac.. greeen does not go to compressor unit that is for fan only (vent).. red carries the same 24 volts... one difference here is that most carrier units only have the one transformer....so you run the red wire is the +pos 24 volt..and then a "common " wire is needed which is the Ground or neg... that wire on a carrier is brown usually but could be different depending installer. The orange wire goes to the pump reversing valve it is always energized when on ac mode...when heater is on in the winter it is heat pump and is not energized so just connect the orange and yellow together... tell me more specifics if this doesn't help and i'm sure I can help you... thanks Chuck
If it is just the condenser fan that means you have a fan relay that has welded shut. Turn power off to your unit and trace the wires from your condenser fan back into the control panel at the unit. You'll have 3 wires going to it. 2 go to the run capacitor and one goes to the fan relay. The one that goes to the fan relay is the part that needs to be replaced. If you have no fan relay and it goes to the main contractor, half of your main contractor is welded shut and will need to be replaced.
