Have a ceiling fan that operated correctly/light & fan functioned properly. The pull chain for fan control/speed broke & come out of switch. Purchased exact duplicate switch an installed. Put each colored wire to L,1,2,3, on new switch, just as was to broken switch. Flip power on at standard ON/OFF wall switch (no dimmer, or separate FAN/LIGHT switch... only on/off)... Light operates normal... when pull when chain pulled on the fan for fan speeds, nothing happens (fan does not spin... but with one of the pulls ,DO HEAR A SLIGHT HUM FROM MOTOR, BUT NO ROTATION)... BEFORE REPLACING SWITH, FAN/LIGHT WORKED, EXCEPT FAN STUCK ON MED SPEED DO TO BROKEN CHAIN... HENCE HAD TO FLIP WALL SWITCH TO TURN OFF. What went wrong? Pardon the ignorance on something that is so simple... THANK YOU... Ken
