Re: wiring a single phase 14 in fan

Please do not rate this as an answer, just wanted to see if you have a model number of the fan, motor, speed controller, etc. many people here can help you, but providing an answer without knowing exactly how the default wiring is set up is never a good idea.

I have 2 wires plus ground going from switch to fan at fan there are several wires I can not figure out a hook up

if single speed fan you have 3 wires and ground
if 3 speed fan you have 5 wires
if 1 speed 2 wires are are the power and the other one is a capacitor wire at 1.3uF 1.5uF 330v you need to have the wiring chart for the motor or you could work it out with a ohm meter or seek the help of a sparky

How to Reverse the Rotation of Single Phase Capacitor-Start Electric Motors

Reversing the rotation of electric motors can be done easily with 3-phase motors. This can be easily achieved by swapping the connection of any two motor leads. But 3-phase motors are usually found and used for industrial purposes. The ones found and used in our homes, from water pumps to electric fans, are single phase capacitor-start type motors. Unlike 3-phase motors, reversing the rotation of single phase electric motors is no easy task. Swapping any two motor leads will not result in the reversal of the motor rotation. Analysis of the motor windings and connections are necessary before any modification can be done to achieve the desired result. Let's take a 3-speed single phase capacitor-start electric motor with electrical diagram shown below as an example. Make sure the motor is disconnected from the power supply before attempting to follow this tip. This tip is intended only for individuals with electrical knowledge, necessary tools, and understand the risks associated with handling electrical equipments and devices.


The first step in the process is determining the start winding which is connected to the line (AC white) and to one side of the start capacitor. To accurately determine the start winding, disconnect all motor leads from the start capacitor and the speed switch for multi-speed motors and then setting your ohmmeter to the lowest scale (R x 1), measure the resistances between the AC white line and each of the motor leads connecting to the start capacitor. The one with the least resistance is the starting winding lead.

Once the start winding lead going to the capacitor is determined, reconnect the capacitor then connect the black AC line to the found start winding lead (marked X). Connect the white AC line to L of speed switch, the motor lead formerly connected to AC white to 3, red to 2, and white to 1 as shown below. Leave the green/yellow ground wire connection as is.


Below are the wiring modifications for 2-speed and single speed single phase capacitor-start electric motors.

How to Reverse the Rotation of Single Phase Capacitor-run Electric Motors

theres a three wire on it,1 in line1 this connected in one lead terminals of capacitor and 2 starting the other lead terminal of cap.,3 lead running,just change the connection of lead line capacitor to lead running wire,make vise versaand it will change the rotation

Can i test run the fan motor by bypassing the capacitor

Maybe: If you can manually rotate the motor to get it started.
The capacitor is on start winding, and causes sudden release of amps that starts the motor.
There are two (or four) windings in each single phase motor.
Both receive power at same time.
One winding is the start winding, which can be considered 'low gear' on a transmission. The capacitor is on this winding and gives burst of enough power to begin rotation.
So when a motor just hums, and doesn't rotate, then the start winding and/or capacitor are suspect. Dry or worn bearings are suspect too.
The other winding is the run winding that brings motor to up to speed.
On fan motor, the run winding can have multiple connection points for selecting different speeds.

Hi, I have an aloha 3 speed oscillating pedastal fan. motor is almost seized. can it be fixed?

What is the estimate rotation rpm at fastest speed ? Normally pedestral fan is a 6 poles or 4 poles single phase motor?

You have a special fan there. Hunter Originals are my specialty.

There are two ways to accomplish a slower speed with this fan.

1. A wall variable speed control, solid state, rated for 3 or more amps, regular fan controls will not work as your fan draws 2.5amps on high, not even new ones that are labeled for the Original.

2. Retrofit the fan to make it a three speed. If you're good with wiring, it's really simple. What you need is, a standard 3 speed pull chain switch, not a double pole one like cheaper/new fans have that use capacitor speed control, we are using cap. speed control, but not the same way they do. So you want an "SP3T" switch. You also need an 9 10 or 11 or 12 MFD capacitor (depending on how fast you want your low to be 8 is 20rpm, 11 is 75 approximately). You will remove the switch cap to your fan, and you will find your switch has a black, blue and red wire connected to it. Remove all wires, attach the black to L on your new switch, attach blue to 1, then you need 2 extra pieces of wire. Stick one wire in 2 and the second wire in 3. Now, get your capacitor and hook one side of it to the red wire and position 2, then hook the other side to the wire you put in position three.

Remember to get the Single pole switch for non capacitor speed control fans, if you get the double pole, both winding sets in your fan will be activated, which will draw double current and burn your motor out.

Also, are you aware that your fan uses oil (like an engine) ? and is not permanently lubricated?

I was trying to install a fan control switch on my Patton floor fan and took the 3 speed switch out and disconnected the wires and cannot figure out what wires (too many colored wires) to connect to the 2...

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

Changed out blower motor on elect furnace.the old motor had three wires one fed the motor is revirsable has purple wire,red,blue,black.hooked up purple 1st phase,red for high 2nd phase. is...

hmmm . you better check on that before firing it up ... normally the colored wires are for different speeds .. only one speed can be connected at a time .. usually the high speed winding is used for air conditioning and a lower speed winding is selected by a relay for heating .. ... the way the capacitor is hooked up determines which way the motor will turn .. your old motor with just 3 wires was probably a single speed motor .. normally the black wire will be connected permanantly to one phase .. the other phase then goes to the selected speed winding (color of wire) .. one goes to the starting capacitor . the others even if not connected will be hot electrically so need wire nuts to prevent shorts ..

Hampton Bay Ceiling Fan At Slow Speed

I recently replaced my hampton bay fan for the same reason (slow at all speeds) and discovered scorched and melted capacitors and wiring inside the fan. My suggestion is to stop using fan and replace immediately.
