I've opened the switch box on the wall, nothing visible. *I went into
the attic to check for signs of rats or other varmints eating the

My first inclination is to replace the switch. *Replace the fan if the

Any advice?

Here is a possibility:
Usually the fan casing has two switches: One for the fan and the other
for the light. Do the following: (1) Turn both switches on the casing
off. (2) Turn the wall switch on. If the CB trips, replace the wall
switch. Else, (3) In succession, turn wall switch off, turn fan
switch on, turn the wall switch on. If CB trips, the fan motor has
short. Else, (4) repeat step (3) this time with the light switch.
