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.
