Open the indoor unit and write down which color is attached to what number, they should be wired exactly the same on the outdoor unit and visa versa.

Wiring- Connecting wiring on replaced fan motor


Your new fan motor should have a diagram with it or at least printed on the side of the motor, that will help a lot from your end. As for me, I don't know what unit you have, so I will try to help you with just the basics.

Your old motor probably had 3 wires. One went to the contactor, that is the "Line Voltage", one went to the Common terminal on the old capacitor (COM), that's the other "Line Voltage" wire, and the last one went to the "FAN" terminal on the old capacitor. The reason the old capacitor looks different is because it works for both the compressor and the fan motor (split capacitor). You still need this hooked up for the compressor to work.

The new fan motor.
These vary in brands and wiring so I can not tell you the colors without knowing exactly which motor you have. On the new motor wiring diagram, you should see the "Line Voltage" as described above that 2 of the wires are ran to each other (just on the diagram, not wired together on the unit). This is your power wire that goes to the contactor on the unit, usually black, and your Common wire that runs to the capacitor. You can still run this wire (COM) to the common terminal on the old capacitor since you still have to use the old capacitor for the compressor and the common terminal should still be jumper-ed from the contactor to the (COM) terminal. Then you will probably have 2 wires for the new capacitor, usually Brown and Brown/White. These wires run to each side of the new capacitor and doesn't matter which terminal. Then you will take a new jumper wire from the (COM) terminal on the old capacitor to the terminal on the new capacitor that has your Brown/White lead. Make sure you secure the capacitors inside the unit so not to touch anything surrounding them. Your new motor might also be a "Reversible" motor that has reversing wires also. Again, your new motor diagram can tell you how to hook these up. You have to have it spinning the right way, most of the time it is CCW (counter-clockwise).

I'm sorry I can't be any clearer on this, but without knowing the brands, models, etc, I'm in the dark. If you need any additional help, I would be glad to help! Good luck and hope you get to cooler days!

I need a manuel showing me how to hook back up my fan to capacitor after i took it apart.Forgot how to wire it back.Where can I find a manuel to download.wiring.


*CAUTION*
Capacitors hold a large electrical charge and will discharge upon contact with your skin. This is enough to stop your heart and cause death. If you are not confident of your abilities around these devices then please leave any testing or repairs to a professional.
*Rant off*

Most air conditioners, and all electrically operated equipment, will have a wiring diagram written somewhere inside of the unit. Usually they are a printed piece of paper pasted on the inside of the cover or on the rear of the unit. You don't state what kind of system you are working on so I cannot be more specific than that.

On split systems, or central air systems, the two brown wires from the fan go to the capacitor but yours may be different.

UNIT WILL NOT RUN WIRING DIAGRAM IS DAMAGED SO REPAIR PERSON CANNOT FIGURE IT OUT


a good service tech dont need a diagram he will just know how to do it. took me around 2 years before i could rewire a unit . you need power to certain things and you just go from there
ie: you need power to blower. you need power to transformer need secondary voltage from transformer low voltage makes the switches for things to come on or off. the compressor and starting for it has to be right or it wont run contactor has to be wired right. run cap has to be the right mfd and wired right are you working on something thats 230 volt single phase or 3 phase
need more info to help you

Hello i want to conect a trane condensator 2twb0036a1000ba to a trane evaporator mww536k10raa i need a wiring diagram


Your wiring concerns may be more with the thermostat wiring connections than the condensor connections. if you look inside the cover of the evaporator unit (usually called air handler) there should be a wiring diagram glued to the panel cover. This diagram will show all 3 units (stat,cndsr, airhndlr) and the wiring needed between them. Trane and Lennox are notorious for having the most wiring between components. You also need to be sure the stat is the correct type for the system (i assume this is a heat pump system) and there can be as many as 9 wires from stat to system and 6 wires from inside to outside units. Also, the stat will have a wiring diagram with it that shows most typical system wiring including the wiring between in and out units. Your best bet (if you have no diagram on the unit or with the stat) is to call trane and have their tech division fax a diagram to you. Goodluck,Macgivor

Air Handler Blower


if you have a meat thermometer, place it in the vent when the air is on, it should be cooling somewhere around 15-18 degrees F lower than what actually temp is, so if its 84 degrees, your unit should blow around 67 degree air out of the vent. if it is not call a tech. your system could be under or over charged.

Need wiring diagram for a ac060x1022b air conditioning unit. i installed a relay breaker on the unit outside and need to know that i wired it correctly. took a couple of weeks to get the right part and now...


Should be three wires coming out of your box. Take the ground and connect it to the ground stud inside the unit. And then take the black and connect it to the contactor on the L1 side and then the white and connect it to the L2 side. Just match the black to black and white to white. Across the contactor.

So just to make sure I expained it good. Contactor sits just inside your case you have two small wires that are from the t-stat. Only 18 gauge. then the bottom of the contactor has two connections so power comes to the bottom side that is what you are hooking up. Now on the top you should have maybe 5 or 6 wires coming from that. But those are there already.
