The replacement switch has 4 wire ports marked L,1,2,3. The fan has a black wire (power) and 3 other wires from a plastic capacitor box, 1 green and 2 brown. How do the wired connect to the switch?

I'm assuming from your question the 4th wire in your electrical box is a bare copper wire which is the ground. The green wire gets wire-nutted to that. The white wires get wire-nutted together. I'm guessing you have two switches installed in the wall for the fan because there is a black and red wire coming from your electrical box (one for the light and one for the fan) connect the two black wires together. The red wire is then connected to the blue wire in the fan which is the light.

No it is not going to. If it does then why did they use the four wires in the first place? Duh!

If you cap the ground wire nada will work - if you cap one of the wires going to a motor winding, that speed will not work.

pretty sure its the 3 speed pull chain switch.$4.50 to $6.00 at home depot or lowes or hardware/elecrtical store.
how 2 replace switch.
1.turn off breaker to fan/fan lights,probably that whole room.
may need extension cord & floor lamp from closest room with electric, so u can see.
2.need 6ft step ladder to get up to fan.look see how to get to fan speed switch. speed switch unscrews from outside but body of switch is inside fan cover.
3. need to take fan off ceiling to replace switch.
4.switch has 4 wires, power feed into switch and 3 selector
wires that go to high speed winding,medium speed winding and low speed winding.
speed selector switch has 4 settings, off, low,medium,high.

about ac circuits , black wire is 120 volts, hot.
white wires are neutral return wire. an ac voltmeter will read 120volts ac with its red and black probes between black,hot and
white,neutral.
white= neutal=ground which is green. If wired properly and polarity was observed, white and green ground wires both connect to the neutral ground buss bar in the circuit breaker panel box and are the same electrical point.

black wires,and the selector handle getting the hot juice into the fan and white returns the used juice to the circuit breaker panel box.
If polarity was observed, you can touch white and ground without getting a shock.
black will jolt or even fry you dead, so make sure the breaker to the fan is off, so that the circuit is de-energized before you touch it.

PLEASE NOTE--- make drawing on paper of what color wires from the fan motor go to what color wires on the selector switch.
If the switch has 4 black wires, you need to put different color electrical tape as a marker, on each wire. or ,to be cheap, you can use white paper,scissors to cut paper,and pencil and write 1,2,3,4 on the paper and tape to the 4 switch wires.

that is: wire # 1 from the switch goes to the black wire from the wall--ac hot
wire #2 from switch goes to yellow fan motor winding,
wire # 3 from switch goes to orange wire from fan motor

wires are specific and NOT interchangeable.

how to replace fan motor speed selector switch.

1 - gray
2 - brown
3 - green
L - should be black
The other gray should be connected by wire nut to the other grey to reversing switch.

Also, you should have two wires, white & black w/ white stripe, at bottom of fan to hook up light if needed.

Copy following link for simple walk-thru how to wire occupancy switch
http://waterheatertimer.org/How-to-wire-occupancy-switch.html

This device is made to replace single-pole switch.
Power to fan: note the horsepower range for device: for example if occupancy switch is rated 1/4 Hp, then it will work for ordinary bath fan. If device is rated for 1/3-1/2 Hp then it is rated for whole-house fan.
Each fan motor will have rating plate showing Hp. Check rating labels for each device.

I never could find the 5 wire 4 speed replacement. I did however find a solution.

If you want to control both the light and the fan using 3-ways, then just wire 2 sets of the 3-way circuits. For this you need two sets of 3-wire between the switches, and one 3-wire cable from the switch location to the fan/light box.

At box #1 (a 2 gang box), you will run a power cable (marked cable #1) into it. From there you run 2 sets of 3-wire cables (identified as cable #2 & cable #3) to the other switch location, which will also be a 2-gang box (box #2).

Also from box #1, you will run a 3-wire cable (cable #4) to the fan/light box (box #3).

Hook up is as follows:

Box #3: connect black of cable #4 to black (fan), connect red of cable #4 to blue (light), connect white of cable #4 to white (fan/light), and connect the bare to the green.

Box #2: Connect white of cable #2 to identified terminal on 1st 3-way switch (#3). Connect red & black of cable #2 to the remaining screws of 3-way switch #3. Next connect white of cable #3 to identified terminal of 2nd 3-way switch (#4), and connect black and red to remaining screws. Tie all grounds together and terminate to both switches.

At box #1, connect black from cable #1 to whites in cables #2 & #3, using a wirenut. Connect white in cable #1 to white in cable #4. Connect black and red in cable #2 to 3rd 3-way switch (#1) and connect black and red in cable #3 to 4th 3-way switch (#2). Connect black in cable #4 to identified terminal of 3-way switch #1, and connect red in cable #4 to identified terminal on 3-way switch #2. Tie all grounds together and to the switches

These fans are manufactured by a number of overseas companies and sold exclusively by Home Depot. They do not have a standard color code for the fan switch. What you can do is turn off the power, keep the white neutral connected. Then using the black power wire fro the ceiling, take one of the switch wires and connect to that black, turn the power on and observe the speed .. low mark it 1, medium mark it 2, high mark it 3. Repeat untill you have identified all the speed wires. Then connect these wires to the 1,2,3, terminations of your new switch

Tell me what you are wanting to accomplish. Are you wanting to run each fan off a separate switch in the same duplex box? The reason I ask is because you are using 12/3 wire to the fans. If you are just going to have 2 switches then you are only going to have power to each fan from each switch. Therefore there is no need to run 12/3 wire. 12/2 is all that is needed and you would simply tie the fan and light wires to that one power source at the light/fan. Now if you are wanting to have a switch for the light and another switch for the fan at each location then that will take 4 switches. You can buy double stack switches and have 4 switches in a double gang box. Is this new construction or old? Please explain what you are wanting and I will be more than happy to explain how to wire it.

I have similar problem, although I have 1 high speed and 2 lows, no medium. before I replaced the switch (which was no help) I marked the wires.
