Question about Speed Ceiling Fan 3-speed Switch By Westinghouse 77021

2 Answers

Changing the 3 speed switch on my westinghouse ceiling fan

I believe I am returning the wires to their appropriate positions but I only get a hum from the fan when I turn the main power back on.

Inside the fan I have purple, yellow, gray and black
The switch the hardware store sold me has black, red, white and blue

Westinghouse quoted me the 77021 switch but the local hardware said they don't buy these replacement parts from Westinghouse and that the one they recommend will fix it.

They say even thought the wire colors don't match, as long as the L,1,2,3 are spliced appropriately it'll work.

It's not working!
Where do the the purple, yellow, gray and black correspond in relation to L,1,2,3?

Thanks
CP

If you are careful and take the hot coming into the fan from the power source and connect it to the colored wires one at a time, you will be able to find which one is high, med. and low. Then connect them. Hot in is L, 1 is low, 2 is med, 3 is high

If the fan only has 2 wires a blue and a white, blue goes to power supply white goes to neutral. Fan switch itself provides the 3 speeds.

Question posted under 3-speed switch

1) Are you replacing the 3-speed switch?
This is a field with much discussion because Westinghouse 4-wire fan switches vary.
Process of elimination is needed to find hot line. From there you test each wire to the hot line wire to determine which wire or combination of wires makes up low, medium, and high speed.
Open following links for some resources:
http://waterheatertimer.org/How-to-wire-Cooper-277-pilot-light-switch.html#3-speed
http://www.ceiling-fans-n-more.com/ceiling-fan-pullchain-replacement-and-repair.php
http://www.atlantalightbulbs.com/ecart/catalog/westinghouse-6.html

2) Or are you looking at fan connection wiring at ceiling?
Green wire goes to bare ground.
Fan should have hot and neutral.

Hot line should be black.
Neutral should be white.

Red usually goes to light
Blue is normally not there.

Where is the white neutral wire?

Take multimeter set to read ohms and test black wire to each other wire.
Process of elimination should reveal correct wiring.

I have a Hampton Bay ceiling fan. I bought Westinghouse 77021 to replace the fan switch. I have black, white, yellow and blue wires inside the fan's case. Where should I connect these wires? Jane


Hello. Yhe most common combination for this wire combination is: L - White, 1- Black, 2 - Blue, 3 - Yellow . However this is assuming your 77021 (the fan) has three speeds and the pullchain has four wires. Here's a link to some very good troubleshooting advice: http://www.ceiling-fans-n-more.com/ceiling-fan-pullchain-replacement-and-repair.php

Westinghouse Lighting 3speed Ceiling Fan Switch 7707500: I just replace the speed control switch in my Hunt...


Typically the old and new switches have no relative relationship to each other .. One way to figure this out is shut off the power and then using the black power wire attach each speed wire to it and turn power back on to observe the speed .. mark the wire with the speed 1, 2, 3, .repeat this untill all the wires are identified .. . then you can put the wires on the appropriate terminations on the new switch ..

Westinghouse 3-way fan switch can not be turn off.....


I had a similar problem. A replacement Westinghouse 3-4 wire 3-speed replacement switch from Home Depot, part # 77020, is a multi-pole that did not work with my ceiling fan. There was no "off" position. I found the correct replacement switch, sold under the "Harbor Breeze" name, part # 033905, which is a single pole switch, at Lowe's, at a better price!
