Question about Speed Ceiling Fan 3-speed Switch By Westinghouse 77021
I have a harbor breeze ceiling fan on a dimmer switch. the fan has 2 green, a blue, a black and a white wire. the ceiling has 2 copper, a black, a red and a white. when the fan blue is connected to ceiling red and black to black, the light works but not the fan. when the fan blue is connected to ceiling black , and ceiling red to fan black, the fan works but not the light? what do i need to do?
You have 3 options. You can connect the fan blue and the fan black to the red ceiling wire. Then you will need to control the fan and light with the strings. The wall switch will turn off everything. Option 2 is make sure that there is a switch wired to the black ceiling wire. If there is a switch I would check to make sure the switch is working. Option 3 is to purchase a remote control unit for both and leave the wall switch to shutoff the whole unit. Hope this helps.

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
and a link to Diagrams: http://www.hurontel.on.ca/~taitg/pages/cfan.html
Hope this helps, and don't forget to rate our help. Thank you.

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:
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.
