Since this will connect the line & 6в™џ on high speed setting, and line, black and 3.5в™џ on medium speed setting, the black and yellow wires appear to be swapped. yellow capacitor wire (6в™џ, 200V) goes to switch terminal 1.red capacitor wire (3.5в™џ, 200V) goes to switch terminal 3.blue capacitor wire (3в™џ, 350V) goes into motor housing.black capacitor wire connects to a reverse switch and switch terminal 2.Old schemeДЄ simplified wiring scheme, showing how the switch connects to other components (other connections for those components are left out):Д¬apacitor (assumed to be correctly wired): The capacitor has component # E175257 and manufacturer logo:Д«oth the old and new switches go through the sequence of terminal connections shown in the wiring diagram above (e.g. 3-speed, 4-wire pull-chain switch with terminals L, 1, 2, 3.Is this correct for the general case? Below is what I have in particular would someone confirm whether the wiring scheme I propose is correct? Components This way, high speed bypasses the capacitor, medium uses a higher capacitance and low the lowest capacitance. Whatever the capacitor and fan manufacturer, I expect 'hi' speed should connect the line/power and common wires, 'med' the line/power and two of the capacitor wires (lower voltage, if not all equal), and 'low' the line/power and the lower capacitor (and voltage) wire. From what I can tell, 3-speed fans should be wired something like what's shown in the following diagram: The switch was stuck 'on' at low speed for years, so I couldn't check what speeds the fan ran at for each setting with the old switch (I'm hesitant to wire it incorrectly to test with the new switch). I couldn't find a wiring diagram for the specific fan (and capacitor) to confirm the correct wiring, but after examining how it was connected, I suspect the switch was wired incorrectly when installed. I put everything back together but put some oil in the chain near the brass coated screw chain exit port (I could tell that corrosion had destroyed the original chain at this point, probably from condensation over the past 8 years).I'm replacing the fan switch in a Hampton Bay fan + light combo. Once it was off, I was careful to see how the parts fit together, used a small pliers to pull apart the metal pincers that were clinched on the original chain, put the good chain on it and re-pinched this metal piece on it than reassembled the chain assembly so that the spring and ratchet system it contained worked correctly in my hand (with the distinct 'clik-clik' when the chain was pulled), and re-attached it to the black piece. There were some tabs on the clear portion that could be 'pushed in' to get the pull chain assembly off the black elec. I had access to the pull switch and could see the broken chain inside it. The fan designers had included a wire harness and quick release that allowed be to remove the entire lamp and fan switch assembly to make it easier to work with then while standing on a ladder. Then I removed the lamp portion of the fan in which the broken pull switch was located. First I cut off the power by turning off the circuit breaker. Which I did! It was rather easy, took about 40 minutes. Since it was a four wire switch that was interfaced to a 4 wire sealed capacitor that seemed built into the lower light assembly on our fan/light system in out porch, and since the switch was definitely no good as it was and perhaps needed to be replaced, I decided to just take it apart to see if I could attach what was left of the long pull chain. We broke the pull chain off inside our pull switch in the fan/light assembly last night.
