Part # Part Description
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.

Summary

Pull Chain Switch Replacement

Step 1: Remove Switch Housing

Remove the knurl nut from the pull chain switch and pull the switch out of the housing.

Step 2: Compare and Transfer Wires

Compare new and old switches, then transfer wires one by one, matching letters and numbers.

Step 3: Wire Insertion Technique

Use a paper clip to release wires from old switch holes and insert into new switch holes.

Step 4: Wire Transfer Process

Insert paper clip, pull wire, and insert into new switch hole until all wires are transferred.

Step 5: Reassembly and Testing

Reinstall switch, screw on nut, replace housing cap, and test all fan speeds.

Run Capacitor Replacement

Capacitor Identification and Leads

Identify the run capacitor block and its wires, noting tinted wires for easy insertion.

Step 1: Locate Components

Locate the pull chain switch and speed control capacitor block in the switch housing.

Step 2: Remove Old Capacitor

Remove the knurl nut from the pull chain switch to access the capacitor block.

Step 3: Remove Capacitor Block

Remove the pull chain switch and the run capacitor block from the housing.

Step 4: Connect Gray Wire

Replace the non-tinted gray wire on the new block with the old block's gray wire.

Step 5: Connect Remaining Wires

Transfer remaining wires (gray, green, brown) to the new capacitor block and reinstall.

Start Capacitor Replacement

Capacitor Block Identification

Identify the start capacitor block and ensure replacement values match the old unit.

Step 1: Locate Start Capacitor

First locate the start capacitor block within the fan's switch housing.

Step 2: Remove Run Capacitor & Wires

Remove the run capacitor block and locate the two wire nuts connecting wires.

Step 3: Replace Start Capacitor Wires

Place new capacitor block next to old, replace wires one by one using wire nuts.

Step 4: Reinstall and Test

Connect all wires, reinstall the start capacitor block, and test the fan.

Reverse Switch Replacement

Prepare Reverse Slide Switch

Cut and strip pink and yellow wires from the plug, disregarding other wires.

Step 2: Remove Old Reverse Switch

Pull up on the reverse switch to remove it from the switch housing.

Step 3: Position New Switch

Place the new switch next to the old one, starting with connecting pink wires.

Step 4: Connect Pink and Yellow Wires

Connect new pink wires to housing pink wires and yellow wires to housing yellow wires.

Step 5: Connect White/Gray Wires & Test

Connect white and gray wires, reinstall switch, check work, and test fan.
