I never blew a bus fuse in the 7 years I've lived here.
I blew one over the winter, and one blew today.

Anything I can check before calling for service?

I cleaned the filters about 2 months ago.
Would clogged filters cause the blower to work hard enough to blow the
fuse?

Mitch, tell us more. What is the fuse rating and what does it protect?
