It is an old Rheem RGAA-100C furnace, On the old motor the wires was: White, Brown, Red, Black and Blue. On the new Motor it has Brown, Brown/White, Black, Red, White, and Blue. I don't know how to wire it back. They do not make the old motor anymore, this motor was the replacement. Could you please help. On the circuit diagram on the motor says: [Blk (Hi) or Blue (Med) or Red (Low)] to Line. There should be a schematic printed on a sticker on the motor. Without knowing the make and model, or looking at the diagram. I'm guessing based on other motors. One common "standard" is as follows: White = grounded (neutral) (clockwise). Black = High speed. Blue = Medium speed (medium low). Red = Low speed. Brown = Run capacitor. Brown w/ white = Run capacitor. Yellow = Medium speed. Purple = Grounded (neutral) (anticlockwise). Optional wiring available on some motors. However, without the make and model, or the schematic, this is just a guess.

The two brown wires (Br and Br/Wh) should be connected to the capacitor. If you don't have one, you may need to install one. The brown wire from the old motor should have been connected to it, so try to remember where you removed the brown wire from. The white wire from the motor, should connect to the white wire in the junction box.

Husky Lab Mixed Puppies For SaleIf you can remember which color wire was connected to the red wire in the junction box, that should be the same color wire to hook back up.

Typically the blower is run at low speed when in heating mode, but that's no guarantee that your equipment was set up that way. I wasn't able to locate any documentation on your equipment, and without a schematic I can't be any more specific. If you could include a good photo of the schematic, I could show you where to make the connections. You should be able to find a schematic in the manufacturer's documentation, or on the furnaces access panel.Browse other questions tagged hvac or ask your own question. Since last I posted, I moved WAY south (lil warm down here) and the house I moved into was a foreclosure so a few things needed done, namely the AC and furnace. When the guy did the job he said he would (did?) leave the old motor behind so I could use it for some airflow in the garage. Here's what it looks like... Onto my real questions -- I don't have the wiring diagram, but if I had to guess, I'd say that plug is a speed control (black the common?), and the white is the hookup.

has anyone rigged one of these up and if so, how'd you do it? ==== updated 7/1/2012 ==== I got motivated today and started to clean it and look for tags that might help identify what it is -- and well, I think this answers everything (and I got a good picture of it!). It's a Westinghouse 323P683 1/4 hp, 115v motor so xcythe you we're close on those wires (much better than my guess). If I'm reading this correctly... White-Red : low speed electrical hvac garage furnace blower Squirrel cage blowers make great fans. Black is ground, white-negative and red-positive. Looks like blue, white and red coming from the motor. Read the info on the motor, it should have split capacitor in it, may have to change the wiring from 220 to 110. Looks like a 1/4-1/5 horse. Ask a local HVAC guy, feed his ego and be rewarded. If its a 110 just throw a three prong on it and breeze away. I pulled some romex off the coil and pulled a spare heavy duty three prong outta my tool bucket and had a great workshop fan w/ a super long cord.

(put a triangle shaped piece of plywood on one side to stabilize it, and a small board 1x2 across the front as a foot/stabilizer, made it quiet) There's not enough information here to give you a straight answer. It looks like there is some control circuitry in the metal box that's attached. I'd normally say remove that and figure out the wiring directly to the motor, but it appears that the start capacitor goes into this control box, and since that's necessary for the motor to start, you may need to keep the control box and figure it out. I'd open the box and see if there's a schematic on the inside cover that gives any idea. If not, then getting a schematic for your old furnace would be the first step, if that isn't available or known you can use some techniques with a multimeter to determine how the motor is wound and use that information to hook it up. Lastly, check with the guy that made the suggestion - he should have an idea of how to hook it up to a plug. It is a split phase motor there will be a run capacitor some where .

the wiring is white is common black is high blue is med red is low . you have to look at the sticker on motor to find out what voltage the motor is it will be either 115 or 230 volts but not both. if your just using it to move air pick the speed you want and insulate the other 2 wires so if you want high put power to white and black insulate blue and red separately and it may or may not be reversible there is usually reversing plugs on the side of motor if is reversible That look like a 1/3 hp motor, which is a 120 volt motor you got 6 wires on that motor three is for fan speed and they are black for high, blue for med.and red for low. you have a capacitor on that motor three wires are on that capacitor a brown, on one side and a yellow and white on the other side, the white wire is one side of power choose the wire speed you want and cap off the other two so that they don't touch and wire that speed to the other side. Just get an extension cord, cut off one end and wire the ground to the green ground lug or wire.
