Motor Wiring
Old Motor
Brown wire is Start
Yellow wire is run or Power
Black wire is High Speed or Common
The other two taps are speed taps, but you have a single speed application
And high speed is what you need ,that’s why there’s not any wires
on Red and Blue if high speed was to much then you would move the
Black wire to one of the other taps RED low speed or Blue Medinm speed
New Motor
White goes to the Yellow wire from the capacitor
Black goes to the Black wire you took off of high speed on old motor
Of course both Brown wires go to the capacitor and Green to ground
If a capacitor doesn’t discharge it doesn’t mean it’s bad
but the capacitors don’t last as long as they used.
Any time you put in a new motor always replace the capacitor
It will save you a lot of time and grief later on.

Hi, this is a different wiring diagram then what you have . The 2 brown/wht wires are for the run cap only. Black and white are t-1 and t-2. They sold you a motor that takes its own run capacitor to run it with just both brown wires. Take the diagram from the new motor back along with your original. They will give you the right run cap to go with this motor. Yes, the red wire is power to fire your existing cap and old motor. You will need another cap to run this motor. Don't put the 2 brn/white striped wires on the old cap! They have to be alone on there own run cap. Go back to the parts house and they will show you very fast the wiring diagram and give you the cap. This is a very easy fix when they give you what you need. Keep me posted and ask them to give you what you need to run the motor. A 5 uf run cap perhaps?
Keep me posted.

Do not connect all the speed together. Do you have an RPM of the old and new motor. I think I can help you out if I had that info. Let me know.

You have a two-speed as indicated by the red jumper wire and brown wire left out for connection. These two wires connect to the speed switch with the red jumper to low speed and the brown wire to high speed. The black electrical cord wire connects to the L or COM terminal of the speed switch. The diagram below should give you better understanding on how the motor and the speed switch is wired.

The L/COM terminal makes contact with terminal 1 for low speed and terminal 2 for high speed. The OFF (0) is not shown.

WIRING DIAGRAM FOR A DAYTON EXH. FAN FOR A GREENHOUSE. tHE FAN GOES TO A THERMOSTAT THEN TO ELECTEICAL BOX


So far, I cannot locate a wiring diagram for an installation. However, this is a single phase "shaded pole" motor.

For a single speed, shaded pole motor, there are only two power wires. For a dual speed motor, a third wire provides a second speed. One wire will be one side of the motor coil(s)...connected to the white power wire. The other wires are the opposite side of one or two motor coils, connected to the black power wire or through a thermostat. A thermostat is simply a temperature operated switch. An additional wire may (should) be a green "grounding" wire.

I have a 3 speed fan with a red, blue, black an white wires, how are the supposed to be wired with power. the wires go to a little black box that appears to just be wires with no circuit board


The BOX is a GE splicer - with 6 wires - 2 grey power wires, then the red, blue, black, and white from the fan motor. I have the same problem and cannot find another GE SPLICER 3 SPEED SWITCH for the fan. All switches that I have tried have 4 connections.........so a WIRING DIAGRAM would be GREAT!

Can anyone offer any help? I have tried every electrical store in the area!

Thanks

Thr issue you are having you need to look on the motor and see if there is a diagram but you have to use the grey and white for a capacitor because i have an older fan that has no capacitor. and use the red for high

Wiring diagram for a 3 way ceiling pull switch.


These fans are manufactured by a number of overseas companies and sold exclusively by Home Depot. They do not have a standard color code for the fan switch. What you can do is turn off the power, keep the white neutral connected. Then using the black power wire fro the ceiling, take one of the switch wires and connect to that black, turn the power on and observe the speed .. low mark it 1, medium mark it 2, high mark it 3. Repeat untill you have identified all the speed wires. Then connect these wires to the 1,2,3, terminations of your new switch

5 speed fan on h&a #5 quit 1st and now all speeds have quit working. What does this sound like , switch or relay. Can I disconnect wiring at the fan motor and tell which is bad with a volt meter.


There is a voltage regulator somewhere in that circuit. it controls the speed of the motor by changing the voltage in the circuit. Trace the wire back from the motor and you will find it, it's between the switch and the motor. They sometimes get hot and stop working on certain speeds. Change it out with a new one and check the amperage on the circuit to make sure you won't cook your new one. Good luck.

Just replaced broken pull 3-speed switch. Fan now only runs on two speeds, need wiring diagram please


I ran into this when replacing the 3 spd switch. The replacement switch has a pair of connections at each position; you would assume the two connections are electrically tied together, they are not. The switch assembly actually has two seperate 4-position rotary switches. If your "L" wire is on the 'inner' connection, then your motor speed wires will have to be as well.
