My ac fan went out on a carrier ac unit. Need wiring help

My ac fan went out on a carrier ac unit. I am replacing the motor with a new one but the new one has 4 wires and the old one has 3 wires. The new motor has 2 wires going directly to the capacitor where the old one had one wire to the capacitor and then split off to many other wires.

How do I wire the the wires from the old capictor inline since there isnt the same wires.

    thanks for the quick reply
    not sure if the model # is correct since not at the house with that ac right now. there is no heat pump

    The capacitor has at least 5 wires coming off of it with one brown wire going to motor. the new motor has 2 wires that go to the capicitor cutting out the old one still having all the other wires connected to it.


    after connecting the capacitor that leaves 2 wires, but the brown to the old capacitor is now dead. How do i tie the brown wire from old capicitor back into the loop?

Use a seperate capicitor for the fan only pick up 1 leg of power from common side of the compressor cap and the other from the contactor or the board in a heat pump situation

Pull off one of the wires to the fan. If it still blows a fuse the compressor is shorted. If not replace the fan motor.

Condenser fan replaced one year ago, fan not turning but can hear motor


the answer to your problem is most likely the motor start capacitor. A AC motor can run in both directions. The start capacitor is used to cause the current to lag behined the voltage which determines the direction the motor will turn. Its posible the start and run capacitors are in one can. so changing one will change the other. However look for a wiring diagram. Do not asume that both capacitors are wired in properly. They may be fighting one another causeing premature failure.

There is probably only 1 wire leading to the F or FAN terminal on the capacitor. You remove the 1 wire to the fan side of the capacitor and connect it to the new fan capacitor. Then you take an extra wire that you will need to make, buy, or find, and connect it from the opposite terminal on your new capacitor. Meaning the other side that of the capacitor. Then connect that new wire from the new capacitor back to the old capacitors C or COM terminal. Clear as mud I know, but basically you run your fan capacitor wire to the new capacitor, then the other side of the capacitor runs back to common on the old capacitor. And beware! Those things can hold a charge!!! Disconnect all power & discharge the capacitor! Hope this helps

Carrier 48NMX042 IFM wont stop, condenser fan motor and compressor wont run


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

Fan motor runs backwards


Make sure the capacitor is connected to the start lead, not the run lead(s). Also some fans come with some wires you can switch to reverse the direction. If your motor has them there will be 4 and the label on the motor will tell you how to connect them. Let me know if you need more assistance or if this helps.

My AC is running inside but the outside unit is not.


could be seized fan motor, failed capacitor, faulty contactor, bad wiring. Turn the breaker off to the unit and try to spin the fan with a long screw driver or something similar but be careful not the bend the fan blade, If the fan will not move don't force it you need a new motor,If the fan spins freely move on open the cover and check the wiring but becareful the capacitor can still have a full charge and shock you even with power off. Other the that you will need a volt meter that can check volts, amps, and capacitors to futher test the unit I suggest calling a local HVAC contractor and having the unit repair and tuned up by have a tune up done you can recoup the cost of the repair with the energy savings from the tune up.

New motor runs but doesn't blow air through the registers


Is the blower wheel turning? Did you by chance have to remove the motor from the blower wheel to work on it? If you did, did you put the blower wheel back on in the correct direction of air flow? Also, did you put the correct capacitor back on the unit so it can get up to the required rpm's? These are things that you will need to check for. If the motor is running and the blower wheel isn't and the wheel is tight on the shaft, then you will have to replace the motor. The brushes may be bad on the unit and it's not turning the shaft. Hope these ideas help.
