Well....let's see.....

1) Car alarm woke me up.
2) Realized I was hungry and craving pineapple for some reason.
3) Found none, but remembered my GF had just bought a few slices of fresh
stuff. While in basement, heard odd watery sounds from furnace exhaust.
4) Munched pineapple because furnace problems were making me nervous, and
pineapple is better than smoking, which I'm trying to quit.
If you can assemble cause & effect from this, my hat's off to you. Just keep
in mind that it was 3:30 AM when this so-called thinking process was going
on. :-)

OK NOW I am unclear - was it the Del Monte pineapple that caused the PVC
pipe to collect water? Or did the car alarm cause the eating of the
pineapple? And is the furnace problem actually fixed, as we all now know
how the car alarm problem will be fixed? !

My new house has a 6 month old Goodman 92% HE furnace. A couple of days
ago,
it began cycling in an odd way. It would begin with the normal warmup
phase
(whatever that is), go to the next stage where it's actually blowing
heat
through the ducts, but afterward, the smaller warmup motor would
continue
running for between 5 and 20 minutes. Other times, the warmup stage
would
go
on for 15 minutes BEFORE heat began blowing, and sometimes it would
never
reach the true heating stage.

By the way, when I say "warmup phase", I don't mean there's a flame yet.
I'm
referring (perhaps incorrectly) to the stage where the thing is checking
for
proper ventilation or whatever it's doing.

ANYWAY.....my neighbor's car alarm went off at 3:30 AM (the tenth time
since
this morning), and since nobody in my house is up watching TV, it's very
quiet. The furnace began doing it's odd thing again, so I went down in
the
basement to curse at it. Because the house is quiet, I heard something
interesting. Standing right under the PVC vent pipe, I heard what
sounded
like water - about as much as you'd hear if you were in the basement as
the
last 3 seconds of water drained out of the bath tub. "WTF?", I said to
myself. I looked up and noticed that the installer had nailed a pipe
hanger
in such a way that the thing had come loose, leaving the 15 ft span of
PVC
with a downward bow in the middle. I went upstairs, had a few pieces of
fresh pineapple, went down to the cellar again, pushed up on the pipe to
straighten it, heard water head toward the outside, and voila! The
furnace
has cycled normally 5 times so far.

Was collected moisture in the pipe preventing the furnace from being
satisfied with the venting?

Or was the pineapple a factor? On the next episode of Nova.....fruit and
appliances....what science doesn't know yet.
