Is the furnace gas, propane, or fuel oil?

Can you tell if the furnace gets warm (but doesn't blow the hot air into the
house), or doesn't get warm at all? If the furnace gets warm, but the blower
doesn't blow, then one possibility is the run capacitor on the blower fan.
Clicking the furnace off and on will sometimes start a fan blower with a bad
capacitor.

As a couple of other posters mentioned, we would like some more information.
I doubt the shopvac had much to do with the problem.

I'm having a problem with my furnace that I hope someone can shed some
light on. The furnace will run and then usually get to the desired
temperature set by the T-stat and stop. Then when the T-stat thinks
it should run again the the T-stat will show that the furnace is
running (it's an electronic T-stat), but the furance will not kick on.
If I am near the furnace, I can only hear a real faint buzzing sound
(which goes away if I shut the power off to the furnace). If I either
turn the T-stat off and on a few times or turn the power to the
furnace off and then on, the furnace will usually kick on (until the
next go around).

It seems to be a furance issue and not a T-stat issue, but I'm looking
for some help. Unless it is something really easy to fix, I plan on
calling a repairman, but I would still like to be knowledgable of the
problem beforehand.

It is a forced air Lennox furnce about 18 years old. I will mention
too that it started doing this a couple of days ago soon after I used
the electrical outlet on the furnace to power a shop vac (I rarely use
this outlet -- and I don't know if this would be related anyway).

Thanks.
