Boy, youj've drawn them out of the woodwork tonight, haven't you?
I haven't seen so much ignorance on here in a long time.

Thermostat and igniter; good, but what specifically do you mean
by the "igniter"?

Assuming it's not a mercury thermostat, does it "click" when
you move it up and down? It should make a click sound at the
point where the heat would turn on or off. It's usually a
pretty quiet sound.

Beyond that, the possibilities range from the little ckt board
the thermostat wires connect to, all the way to the electodes
gap, oil filter, nozzle, and ice/water in the lines. You don't
say where you are, but it could also be frozen fuel in the tank
or a low tank with water/sludge in the bottom to a borderline 24V
transformer, all reacting to the change in heat/cold. Those are
the extremes of course, but I mention them to indicate that it's
not really a job for someone not familiar with how a furnace
works.
Any firends or relatives with experience who could look at it?
How about where you buy your fuel oil? Money's tight, I know,
but if the house freezes, then there are a lot of other things
can be damaged if you're in a cold clime, so try to get him to
bite the bullet and call for help, then come over to your place
to be warm for awhile until they get there.

My son has a Bryant furnace about 10 years old. Within the
past 2
weeks started having an intermittent problem. The furnace
doesn't
always recycle on after being off. He's replaced both the
thermostat
(Honeywell) and now the igniter. Sometimes it comes back on
like it
is suppose to, other times (especially at night), it doesn't.
When
it doesn't come on, there is nothing -- no blower, no flame,
nothing.

Any suggestions.

He recently had a new baby so money is tight.
