I am confused, sorry. Could you explain what your question is?
Should I remove the fan in order to replace the fan swithch. Could I get to it's location where I can remove the switch, without taking the fan from the ceiling. How difficult is it?
Usually you can replace the pull chain switch without removing the fan from the ceiling. Is the pull chain switch located on the upper shroud of the fan? Usually not, because the pull chain is usually under the level of the blades of the fan.
It is under the blades
There should be a cover on that part of the fan from which you can access the pull chain switch. The cover has one or two screws hold it in place.
screws that hold it in place, sorry
I'll try it. I guess if necessary I'll get back with you, okay>
Thanks. XXXXX'm sure you're aware, but the switch has 1,2,3,L for the wires.
