I am having problems with one of my two furnaces. When the thermostat
kicks in, the furnace will light, but the fan won't kick in. Then the
furnace shuts down. If I turn off the heat (i.e. not on heat or
cool), and turn the fan to "on", it just hums (the other furnace works
fine and the fan will run). There is a solenoid that clicks, then the
humming. The fan itself turns effortlessly.

You mean before you pushed the door switch in right, thought you might hand
start it but when you press the button she just stops dead and won't turn
without one helluva growl?

Do you think this could be a problem with the capacitor, solenoid or
transformer?

No,No, and No

Also, I have been having another problem (probably unrelated?) once a
year every winter when I first start the furnace. The fan doesn't
want to kick in but I didn't notice any humming - this appeared to
have something to do with that timer-like dial (is it a temperature
limit switch?). Two taps with the end of a screwdriver and I'm
usually OK for the year.

Any ideas on either problem? Thanks

What you need is to get rid of that dinosaur, your throwing half the
heat literally right up the stack, wouldn't it be better to put the $700 it
would cost to solve your current delema towords a new furnace that at a
minimum cuts your operating costs by 30 cents on your heating dollar., and
realistically can average 45 cents over your current system and thats just a
2stage 80%er with a variable fan. Now for smidge or two more I can cut your
wasted energy down to 3 or 4 cents on your heating dollar instaed of ****ing
away 45 cents or better, on a really cold day you could ****away 50 or 60
cents on the dollar. Uses 60% of the electricty of a standard furnace, for
what it costs to run your blower for 3weeks I can run this fan for a year or
more.

The higher your utility bills are the quicker the payoff in energy savings ;
open a savings account and deposit the difference your heating bill would
normally have been. At the end of the season you can take a nice little
weekend mini vacation somewhere. Its money you would have had to have spent
anyway.

Yes...your welcome.
