Hi,
If it is limit control problem, flame will be off with blower running.
Easy to see it.

It sounds like something is totally wrong. Happy to come
over and take a look, if you wish. I'm in the phone book.

I'm tired of people telling me that there's nothing wrong
with my
furnace. There is something wrong with my furnace.
It's a 10-year-old Amana 45,000 BTU, 80% efficient unit in a
1300
square foot ranch style house. This is my 4th winter in this
house,
and I'm sick of being limited to one habitable room all
winter.
The air coming out of the vents is cool, around 70 degreees
according
to my thermometer. The exhaust to the chimney is smokin'
hot. The
plenum does not get perceptibly warm.
I change the filter regularly. The old filter comes out
visibly just
as clean as the new filter I put in. There is plenty of
airflow
through the unit, as I can feel the cold draft hit my feet
from across
the room when the furnace kicks in.
The flames are steady and clean blue.
I have to close off all the bedrooms and heat only the
living room and
kitchen during the coldest months, otherwise the furnace
would run
24/7 and the temperature would never get above 62.
The pros say there's nothing wrong.

Hi,
To me the furnace is a bit undersized to begin with.
First thing first,
If blower motor has a speed tap, it should run slower than when in
cooling mode.(warm air is light vs. cold air) Does cooling mode work OK
in summer? Had a look at evaporator coil? Is it clean?

What exactly are you telling the techs? If you are telling
them the air coming out of your vents is too cool, they might be
thinking that it is doing the job and tell you nothing is wrong.
Your problem, as I understand it is that you can't keep your
home as warm as you would like. Tell that to the techs. Don't over
think it, that is the job for the techs.
