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

Hello Joanne,Sorry for the late reply. Some 3-speed switches are as easy to replace as giving me the model number and serial number of the fan and plugging a new one in. In most cases though, we ask the customer to write down the color code (which colored wires go where in the switch) then I have to break open the switch to identify it. Since I field phone calls from all over the US and Canada, I ask the customer to mail me the switch. You can reach me toll-free at 1-866-600-3267.

If you have not already done so I would use the black wire as the line. I assume you have a black,white,and bare copper line feeding this fan.Bare copper is the ground so take it to ground screw on the fan.Go black to black then one at a time try each of the other three to to white neutral line.Each time switch fan through all positions. Hope this helps you. Thank you.
