The question here is whether the furnace is hot when it shuts off (blower
problem) or if it blows till it's cool (so the limit switch is OK, but the
burners are not staying on). Or maybe nothing stays on (thermostat or low
voltage problem).

Idiot.
No..the question is, what in hell is wrong with the picture that no one can
see.


We really don't have enough information to be sure, at this point.

You never did.
You do not understand how to go about checking the unit properly, otherwise,
you would know that its only a couple of things..


When it's cold in the house adn calling for heat, is the T-stat sending
the
call for heat to the furnace?

He said it was...

Is the furnace / heat exchanger hot?

It does not matter.

Is it
cycling on high limit switch?

Umm...if it was, thats part of the problem, but prob not the CAUSE.

Are the burners turning off?

All I can say..is DUH!

Does the air
coming out of the registers feel like it's blowing the usual ammount?

Ah...now you hit on something...explain dear hack, how this will
matter...and FORGET the blower motor..since in your own words, you like
selling customers parts they dont need but you have on the back of the
Pinto....

Also, explain what might cause a reduced airflow OTHER than a blower motor,
or anything related to the blower motor....think hard..

I am having trouble with keeping the heat on in our home. The heat will
come on, as normal, but the blower and heat will shut down before reaching
the temperature at which the thermostat is set and the thermostat
continues
to flash "heat" as if it thinks the unit is still on. This normally
happens
when the outside temperature gets below about 20 F.

We called in the heating people and they determined that the valve was
shot
from doing a test that showed that little gas was getting to the furnace.
This was right after Thanksgiving. We had a warm spell and it seemed to
be
working OK, but the last few days have been colder and it is happening
again.

The odd thing is that sometimes it will run for hours and work fine, as
happened last night. I got up during the night to find the temperature in
the house at 64. I turned the heat off (to reset the thoermostat) and
back
on and it ran for a number of hours.

Just a few minutes ago I turned it on after replacing the filter, and it
ran
for about 10 minutes before shutting off, with "heat" still flashing on
the
thermostat.

Any ideas?
