Compressor fan unit wiring

I had to replace a fan on my carrier unit and I did not mark the 3 wires I disconnected for the fan. One yellow, one brown, and one black. I know the yellow connects with the other yellow wires on the capacitor and I think the black goes to the output side of the power block and the brown to the other side of the capacitor, but I am not sure of these two connections.

    Replaced defective fan motor on my a/c unit. Old motor had three wires: black, yellow, brown. New generic motor has black, white, brown, brown w/white stripe. This new motor came with a new two terminal capacitor. Old cap. had three terminals. The black and white wires from motor connect across the line voltage and the other two wires connect across the capacitor. After install and trying to run the unit, found that compressor turns on for about two seconds and shuts down, but fan keeps going. This repeats every 4-5 minutes. Compressor has three wires, two for line voltage and a third that connected to old capacitor. This third wire I connected to the new capacitor, but not sure if connection is right. Could this be the problem with compressor not working properly or is it something different?

Should be OK to hook it up and try it, make sure the fan is blowing out, if not, reverse the wires..

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

I have a Ruud Air Conditioner and need to install a new capacitor, but I forgot how the wires were on the old one. Can you help me in tellilng me which wire goes where.


There should be 3 terminals on the capacitor marked "C" "F" and "H".
A wire from the high voltage contactor goes to the "C".
Another wire from "C" goes to the compressor.
These wires are usually red.
The "F" terminal has a wire going to the fan,usually a brown wire.
The "H" has a wire going to the compressor,usually yellow.
There should be a wiring diagram on the control box cover identifying the terminals,colors and number of wires.

NEED WIRING INSTRUCTION FOR CAPACITOR FOR


On top of the capacitor you will find the terminals marked. One will say C, or Com. The others will be marked fan and herm. There will be a hot wire going to C. Usually this comes of the top of the contactor and is red. Find the wire that runs to the compressor. It will likely be yellow. This will hook to the Herm. Next find the fan wire (probably brown) it will hook to the fan. Hope this helps.

How do I wire a new condensor fan motor to the new capacitor? The old capacitor is longer and it has 3 terminals. the new capacitor is much smaller and oval. It has 2 terminals. the fan motor has 3 wires,...


Before attempting any of these recommendations, First disconnect all the power sources and check your wiring diagrams on the motor and condensing unit.
On the old capacitor if you look on the top near each of the three terminals. Are they marked, fan - C - herm? If they are that is a dual capacitor and that needs to stay because that is also your compressor capacitor.
The Red wire from the conductor is Run and it's connected to C on the old capacitor.
Follow the Yellow wire and see if it goes to the S or start terminal on the compressor, if it does then that is the Start wire for your compressor and it connects to herm on the capacitor.
For the fan motor a lot of times the wiring connections are printed on the motor label.
Check the label, Purple should be run and connect to C on the old capacitor.
Black should be Common and it connects to the opposite side of the contactor as the Red wire. If the Red wire connects to T1 then the Black wire connects to T2.
The Brown wire shoud be the start wire on the fan motor and it connects to the Fan terminal on the old capacitor.
Now if you want to use the new fan capacitor. Take the Purple wire from the motor and look for any marks (red paint or a dash) on or beside the terminals on the new capacitor. If there is an identifying mark then connect the Purple wire to that terminal, if no marks you can connect it to either terminal. Then you need a jumper wire from C on the old capacitor to the purple side of the new capacitor. Then take the brown wire and connect it to opposite terminal of the new capacitor.

Wires


2 brown wires go to a split capacitor if you have a dual cap which has three terminals marked comp fan com if u have this type of capacitor then the brown wire goes to fan and the brown and white gets capped with a wire nut. whenever replacing a fan motor you should also replace the cap or at least check the capacitance to see if it is still good. you have to check it with a meter that test microfarad.you can get a permanent split capacitor and mount it in there then u use the brown on one side and the brown and white on the other side it only has 2 terminals.

Replace thermostat


Typical color codes in Florida are;
white to W1 for heat
yellow to Y for compressor
red to R-RC-RH for power in
brown to W2 and or emergency /auxillary heat
green to G or Fan
orange to reversing valve(o/b)
blue to common.
You can open the control panel on the unit to verify these colors and components.

Wiring compressor


The two terminal cap is only for the new fan motor. Connect the compressor wire back where you found it, on the 3 terminal cap. It's the terminal marked, "herm". The "common" terminal on the 3 terminal cap must still be connected to one side of the 220 power at the contactor. One side of the 220 goes to the common on the compressor. The other side of the 220 goes to the run winding on the compressor AND the common terminal on the 3 terminal capacitor.
