I recently had to replace the three speed switch on my Gulf Coast Ceiling
Fan. Being the bright light that I am, I forgot to mark the wires... So I
guessed when I rewired it. Doing that, I got one speed-medium, and three
settings of off. So, I took apart another fan that we have in the house that
is the same model, made all the wire colors match .. and now have three
setting os off, and one of fast.
The reason I replaced the switch was breaking the pull chain... the fan
worked great on all three speeds, forward and reverse before I replaced the
Does anyone have any ideas what I can do to make it work right?
I have read that the fan speed switchs in ceiling fans vary quite a
bit in how the 4 settings of the switch connect the four terminals on
the switch. So if you have matched the wiring diagram for an
identical, working fan of the same model, perhaps your replacement
switch is not the same switch and has a different connectivity
pattern? I believe that there are identical looking switches with
different connectivity patterns.
A laborious but definitive process to figure this out would be to
first carefully document the wiring of the working fan, then remove
the switch, noting what setting it was on. Assuming there are 4
terminals on the switch, use a multimeter to check each of the six
pairs of terminals to find out if they are connected electrically, and
record the results. Now repeat this three more times, cycling through
the switch settings. This information completely characterizes the
switch, and you can check your replacement switch to see if it is the
Search Google for the part number of the switch (and maybe the manufacturer's
name). Odds are good that you'll find the wiring diagram on-line. Worst case,
visit a dealer who sells that model, and ask to copy the diagram.
You might be able to wire the switch to a window fan and experiment until you
figure it out (assuming it's a 110 volt switch). Just set the fan on high (to
bypass its own multi-speed switch).
Just reading the post, its sounding like the problem is not so much with the
switch as it is with the wires going from the switch to the fan. If im not
mistaken (and I could be) the fan itself has wires that go to the switch and
the electricity goes through the switch to the various other terminals on
the switch. If that is the case, then you need to know which wires to hook
to which terminals. That being the case, trying to find the switch
manufacturer wont help. Using an ohm meter would help you determine which
terminal is live at any switch setting. Remembering that the fastest rpm is
what is supposed to turn on first of course. Not sure I was any help, but
hey, you get what you pay for on here right? :)
