Propane furnace issue?

It was cold in the house this AM. The small fan would come on, the furnace would try to cycle but, would shut itself off after about a minute. All the trouble shooting places said to start with the pressure switch, then the igniter.
I looked all over hell's half acre for the pressure switch....never did find it but I did find the broken igniter that was the problem. The furnace is fixed now, so all is well....except ....where the hell is the pressure switch?
I bought the place in 1998 and the furnace was brand new that year. Were there no pressure switches required back then? I have looked all over the Internet. I can't find the answer, so I came to the place with the most knowledgeable people I know.
I know one of you smart * gentlemen know the correct answer.[:D]

I would have diagnosed it....if I could have found it. I never did find one, so either there is not one, or it works fine.
Therefore, my question....when did they start using them on propane furnaces?
Have you noticed a different sound to the furnace start up?
Back when I had a propane furnace, the 'small' fan (made from plastic) got some dirt in it and wouldn't spin fast enough to develop the pressure required to run the rest of the furnace. I took it apart to clean it and it was scored enough that it had to be replaced.

I have had the hose from the small fan going g to a pressure switch get some dirt in it. Blow out the 1/4 inch clear hose to the metal pancake switch.

That is the issue....I never did find a pressure switch. I know what it does, where it is supposed to be and what it looks like......there just isn't one!

You state in the op that your furnace was a 1998 "model".
Gas Furnace pressure switches did not come about until around 2006 or 2007.
May the problem you're not finding one.

That is the answer to the question I asked!
Thank you!

Pressure switches have been in furnaces since the introduction of the induced draft system back in the late 80's.
Quickest way to find it is, locate a small rubber hose and find both ends. one end will be connected to the press. sw. the other will be conn. to either the draft motor housing or the front panel of the furnace.

Nope....not there...not anywhere.
I was hoping Oakie would take a crack at this. I know he does it for a living.

How did they put something on a furnace in the late 80's that was not invented until 2006??

My furnace was put in around 96.
It has a pressure switch on the stack blower.

If it had one it would be obvious.
The one on mine is anyway.

Pressure switches and regulators of one type or another for furnaces date all the way back to the 40's.
Pressure switches today act more like the brains of a modern furnace. Any small problem detected and it will shut the furnace down.
Even lightly tapping anywhere on the furnace can cause one to shut down.

I thought so, too.
After some internet research, I decided to just test the next obvious part and it was definitely bad. So, I replaced it and voila.....heat! Good thing, too....we're supposed to see single digits tonight.

Here is an amana furnace from 1996 that has a press. sw
this page tells you to remove press. sw. hose to relocate junction box.

I'll have to get it done this spring or summer. [xx(]
