This is a companion post to my prior post titled Ceiling Fan Capacitor Woes which details the search for a supplier of replacement capacitors to restore several broken ceiling fans to full working order. That post also linked to a number of reference sites, and if this topic is interesting, but confusing, it is suggested to refer back to its links. This posting details knowledge I’ve gained in the process of successfully replacing ceiling fan capacitors that had blown, but additionally, understanding of how to alter the fan blade’s revolutions per minute (RPM). To my knowledge and data searches, this speed-alteration information was not detailed elsewhere. Many sites offered hints, presented, to my mind, in a puzzle-like form of bits and pieces, and none of which showed the bigger picture which I felt I needed to both understand how the various capacitor values worked, and minimize the number purchased, unless I simply wanted precise factory-specified microfarad-valued replacements. Even the manufacturer of the fans didn’t seem to include either a detailed or basic schematic of their circuit, something that is historically quite common for appliances.
In some respects, my prior post created more questions as well as providing some answers, (read more . . . )
