Keeping in mind that some motors may be different
The most common wire colors on a 3 speed motor are as follows:
Red- Low speed
Blue- Medium speed
Black- High speed
Brown capacitor wires ( usually two of them connect to the two capacitor terminals doesn't matter which wire to which terminal)
White - Neutral wire on 115 volt systems or the other 115 volt side of a 230 volt system ( note on a 230 volt motor this wire may not be white). Remember this is the most common wiring but different motors may have different wiring.
Hope this helps.

Table fan winding&connection daigram


  • I have a Bionaire brand table electric fan.
    • It has a 3 speed fan motor.
    • The electric motor is a BM-122 Decomin brand 3 speed motor.
      • There are 6 wires:
        • Red wire.
        • Black wire.
        • White wire.
        • Yellow wire.
        • Gray wire.
        • Blue wire.
          • The motor has a 4mu 250volt capacitor.
  • This fan has an oscillating grill with independent sync motor, and timer circuit.
  • Something was wrong with the solid state circuitry (everything worked but the motor!), but a quick test of the motor indicated it does work.
  • The motor uses a start and run capacitor.
  • I decided to change controls to a simple mechanical switch and fore go for now anything beyond 3 speeds.
  • The printed circuit board shows the following connections:
    • Black wire
    • Blue wire
    • Yellow wire
      • Are respective for the:
        • High fan motor speed
        • Medium fan motor speed
        • Low fan motor speed
  • I think the gray wire goes out to the oscillator motor.
    • The Red wire is marked as Line, for the power source.
  • All wires are in continuity with each other EXCEPT RED is not with any other wire. How to Verify Fan Motor Wiring Connections
    • Checking the Motor and Capacitor Connections
    • Double check your connections using the fan wiring diagrams.
    • You should see that there is a separate motor winding for high speed.
      • The concern is that there is a capacitor for the motor.
      • So I'm thinking that the motor may have to start with the slower speeds first.
      • and not start in the high speed because the motor or capacitor has not been designed for that type of operation.

If you're troubleshooting HVAC electrical problems

230 volt single phase ac
The Common wire or circuit on an A/C or heat pump never has a run capacitor in that line.
The Run wire always has the run capacitor in that line or circuit.

115 volt ac
The Run or Hot wire has the run capacitor and the neutral wire does not.

So if you are tracing wires out in a circuit, if there's a run capacitor, it's the Run wire or Run circuit.
The Start wire always goes to the opposite side of the run capacitor than the Run wire and it is the only wire on that side of the capacitor.
The Run wire goes to the run capacitor, then goes to contactor, compressor, start capacitor or fan, so there's usually two wires on the Run side of the capacitor.

WHY DON'T I GET 3 DIFFERENT SPEEDS WITH DL1056 FAN MOTOR?


If you assemble the blower and check after its installed you will find that the speed does change. Not because the motor is wound for slower speed but because the horsepower is lower from one wire color to the other. Red might be 1/6 horse power, Black would be the full 1/3 horse power, Blue is in the middle there somewhere. Generally its black for cool and red for heat just depends on the system. There is a purist out there somewhere that would like me to say that the temperature rise across the heat exchanger should be considered and you can ponder that if you wish. The manufacturer will have a pdf you can access if you like but I bet nobody will ever notice. Hope I helped and good luck.

I got my craftmade ceiling fan about 10 years ago, the fan has now stopped working but the light works, I changed out the switch on the wall that was not the problem sometimes I will turn on the wall...


pretty sure its the 3 speed pull chain switch.$4.50 to $6.00 at home depot or lowes or hardware/elecrtical store.
how 2 replace switch.
1.turn off breaker to fan/fan lights,probably that whole room.
may need extension cord & floor lamp from closest room with electric, so u can see.
2.need 6ft step ladder to get up to fan.look see how to get to fan speed switch. speed switch unscrews from outside but body of switch is inside fan cover.
3. need to take fan off ceiling to replace switch.
4.switch has 4 wires, power feed into switch and 3 selector
wires that go to high speed winding,medium speed winding and low speed winding.
speed selector switch has 4 settings, off, low,medium,high.

about ac circuits , black wire is 120 volts, hot.
white wires are neutral return wire. an ac voltmeter will read 120volts ac with its red and black probes between black,hot and
white,neutral.
white= neutal=ground which is green. If wired properly and polarity was observed, white and green ground wires both connect to the neutral ground buss bar in the circuit breaker panel box and are the same electrical point.

black wires,and the selector handle getting the hot juice into the fan and white returns the used juice to the circuit breaker panel box.
If polarity was observed, you can touch white and ground without getting a shock.
black will jolt or even fry you dead, so make sure the breaker to the fan is off, so that the circuit is de-energized before you touch it.

PLEASE NOTE--- make drawing on paper of what color wires from the fan motor go to what color wires on the selector switch.
If the switch has 4 black wires, you need to put different color electrical tape as a marker, on each wire. or ,to be cheap, you can use white paper,scissors to cut paper,and pencil and write 1,2,3,4 on the paper and tape to the 4 switch wires.

that is: wire # 1 from the switch goes to the black wire from the wall--ac hot
wire #2 from switch goes to yellow fan motor winding,
wire # 3 from switch goes to orange wire from fan motor

wires are specific and NOT interchangeable.

go to www.ehow.com & type into search engine box

Replaced a one speed 230volt 1 phase electric motor with a two speed 230 volt 1 phase electric motor, now have extra wires which color wires do you use or cap??


Look at the old motor and see what the rated rpm was. Next look at the new motor and see if it gives a speed for each wire. If it doesn't give the speed for each wire then look at the rated motor speed. That will be the Hi speed. Hook up the wire that matches the speed of the old motor and cap the other.

A/C blower will not come on


It sounds to me, if your fan will not turn on at all, that it is either a bad motor, or a bad starting component. (capacitor, or starting relay)

All info(model# ect.) weathered off of unit. Need motor for blower. Looks like 4 ton. how many horse power?


1/4 horsepower, 1075 RPM, 3 speed motor with a 1/2" diameter shaft will do the trick. If you have gas heating, you will need the 115 volt motor., If you have electric heating, you will need the 208/230 volt motor.
