How do you change the PULL CHAIN SWITCH ONLY? - This is a question that we are asked over and over again, the information in this section of the service manual will help you. Once you have the right pull chain switch, changing it only takes a few minutes. First remove the switch housing cup or switch housing cap from the fan shown in Figure #1. Now you will need to look at the pull chain switch you are replacing. Match it up with one you are going to replace it with.
If the wrong switch is used, the fan will not operate properly. The problem will be that you will have TWO medium speeds. If you have this problem after changing the switch, most likely you have installed the wrong switch. Most fans with a spinner motor using this type of switch housing cup, use two capacitors together to get the second speed. For more information on how pull chain switches work and how the speeds are controlled in three speed fans, refer to technical bulletin TB-98-30 (#1a) INTERCHANGEABLE - 3 Speed PC Boards and Pull Chain Switch, dated March 30, 1998. The following steps will show you how to change the pull chain switch.

How do you change the PULL CHAIN
SWITCH ONLY? - This is a question that we are asked over and over again, the information in this section of the service manual will help you. Once you have the right pull chain switch, changing it only takes a few minutes.
First remove or open up the switch housing on the fan shown in Figure #1. Now you will need to look at the pull chain switch you are replacing. Match it up with one you are going to replace it with.
(Figure #2)
Step #1
Remove the knurl nut from the pull chain switch shown in Figure #2. Pull the switch out of the switch housing cup with wire attached, as shown in Figure
#2A and remove it from the switch housing cup.

(Figure #3)
Step #2
Compare the old switch you are replacing and the new one. Make sure that they are the same. Compare the letter and numbers on the switches as shown in Figure #3.
When changing the switch you do NOT need to cut the wires. By using a large paper clip as a tool with both the new and old switch side by side (shown in
Figure #3A), you will be removing ONE wire from the old switch and inserting that same wire into the new switch. Continue to remove the wires from the old switch until all wires have been inserted in to the new. The most important thing in doing this, is matching the letter and numbers on the back of the switches as shown in Figure #3.
(Figure #3A) Step #3
Using the letter and number on the switch as a reference, insert the paper clip into the same hole that the wire is in. This is easily done by placing the paper clip along the side of the wire as shown in Figure #4 and pushing the clip into the hole and pulling out the wire.
NOTE: It is very important when removing the wire from the OLD switch has shown in Figure # 4 and and inserting the same wire into the New switch, it is done one at a time. Make sure that the hole position markings match on the replacement switch as shown in
Figure # 3 at the top of this page.

(Figure #5)
Step #4
Once the paper clip has been inserted into the hole with the wire (shown in Figure #5), lift up or press down on the clip and at the same time pull out the wire removing it from the switch as shown. Now insert the wire you just removed from the old switch into the hole marked the same on the New switch (shown in Figure #6). When inserting the wire into the switch you should hear a click, at this time pull on the wire making sure that the wire is held tightly in the switch (shown in Figure #6). Repeat these steps until all wires have been removed from the old switch and inserted into the new one.
(Figure #6)
Step #5
Once all the wires have been attached on to the new switch, push the switch back into the switch housing cup shown in Figure #7. Screw the knurl nut back on to the pull chain switch. Reinstall the switch housing cap on to the fan. Now you are ready to test the fan.
Test all three (3) speeds of the fan by making sure that you have LOW, MEDIUM AND HIGH speeds. If you have two speeds that are the same, most likely the wrong switch has been installed. Again look at the old switch you removed from the fan and compare it with the new switch.

(Figure #1)
The Run Capacitor Black Box has two capacitors built into one block as shown in (figure #1). Match the old block with the new, the capacitor values must be a perfect match. If not, the first and second speeds will not be the same as before.
Once you have found your replacement block, you will need to look at the leads. Some of the wires leads are tinted and some are not as shown in (figure #2A and
2B). The wires that insert into the pull chain switch as shown in (figure #3) must be tinted for easy insertion. If they are not they will need to be tinted, only tint the wires that are being connected to the switch.

Step #1
First locate both the pole chain switch can speed control capacitor block as shown in
(figure #4).
Step #2
(Figure #5)
Step #3
Remove the pull chain switch and run capacitor block from the switch housing as shown (figure
#6). The run capacitor block is held into the switch housing by two sided tape.

(Figure #8A)
Step #4
Place your run capacitor block next to the switch housing as shown in (figure #7). Locate the gray wire that is on the old block that is wire nutted to the gray wire that is in the switch housing as shown. Remove the wire nut and replace the gray wire it with the NOT TINTED gray wire on the new block. Then wire nut the two wires together as shown.
Step #5
Locate the second gray wire on the old block that is connected to the pull chain switch as shown in
(figure #8A). Using a large paper clip as a tool as shown in (figure #8B), remove the gray wire from the switch and replace the wire with the gray tinted wire on the new block. Replace the green and brown wires that are connected to the pull chain switch and the old block with the wires on the new block as shown in (figure #8C). Once all wires have been connected, reinstall both the pull chain switch and capacitor block back into the switch housing and test.

(Figure #1A)
The Start Capacitor Black Box has one capacitors built into a block as shown in (figures
#1A and 1B). Match the old box with the new; the capacitor values must be a perfect match.
If not, this will cause damage to the motor by over heating.
(Figure #1B)
Step #1
First locate the start capacitor block as shown in (figure #2).

Step #2
Once you have located the run capacitor block, remove it from the switch housing and locate the two wire nuts as shown in (figure #3).
Step #3
Place the new capacitor block next to the old one as shown in (figure #4). Remove the two wire nuts one at a time replacing the wire with the wires from the new start capacitor block as shown.
Step #4
Once all wires have been connected, reinstall start capacitor block back into the switch housing (figure #5) and test.

Locate the reverse slide switch assembly as shown in (figure #1). You will see that it is attached with wire nuts to several wires and may not have a plug attached as shown in
(figure #2). The reverse slide switch assembly shown in (figure #2) is the universal part that is used as the replacement for many different model fans. In some cases the plug will need to be removed.
Step #1
Cut the pink and yellow wires as close to plug as you can as shown in (figure #3A). Strip both the pink and yellow wires as shown in (figure
#3B) and disregard the plug and other wires, they will not be needed during this installation.

Step #2
Locate the reverse switch as shown in (figure #3).
By pulling up on the reverse switch as shown in
(figure # 5) remove the reverse switch from the switch housing as shown.
Step #3
Locate the reverse switch and all of the wire nuts attaching the reverse switch to the switch housing as shown in (figure #6). Place the new switch next to the old switch as shown in (figure #7). Start by finding both the pink wires on the old and new switch as shown, this is where will start the replacement procedure.

Step #4
Once you have connected the pink wires of the new reverse switch to the pink wires in the switch housing as shown in (figure #8). Locate both the yellow wires on the old and new switch and then replace them and wire nut them together as you did with the pink wires as shown in (figure #9).
Step #5
Do the same for both the white and gray wires, until all the wires on the new reverse switch have been reconnected to the wires in the switch housing. Check your work; reinstall the reverse switch back into the switch housing.
Rout the wires so that the switch housing cap or light kit can be easily installed on to the switch housing without pinching the wires as shown in (figure #10). Again, check your work and then test the fan.
