Nothing on the list about using a manometer to check the gas and chamber pressures. It might take a few tries to get it over the starting pressure when the pressure is off specification.

Yes, you really have to find out the MAKE and MODEL to get good answers. There IS more than one machine made.
Is it not going through an ignition sequence at all?
electrical problem
failed ignition module
wires fell offIs it going through a sequence and stopping before it lights?
gas pressure low
sensor dirtyhttp://www.heatpro.us/service/ignitor.htm
What kind of ignition system is in the unknown model? Spark or hot surface?

Many residential air conditioners aren’t built to cool off when the outside air is 60F, so the AC could freeze up when not doing what designed to do. Many think that an open window would do cooling then.

You state it is on low burner. That could be taken as the flame is always low, which could be a low gas supply pressure, a restricted pipe or strayed gas regulator, among other problems.
The question would be if you have the pressure instruments a tech would have to examine the pressure and how to use them.

I’d accuse an electrical problem. As the unit was balky from the beginning.

“WHEN do you answer a question with a question. Because you have no clue to the answer?”
Probably exactly that. Rocket Scientist was looking for more information.Would the contractor be liable, even though the might be unlicensed?
Thank you, RocketScientist for giving a useful technical solution as well.
It is permissible on this forum to ask questions to gather more information or to jog getting another view of a solution.

Both problems are serious. If the burner ever comes to a full high flame instead of having a consistent quiet flame, then it isn’t a residential burner. If there is no limit switch, then one should be re-installed.
Find a tech who knows what to do.

Anything you add that can gunk up a leak can gunk up everything in the system – pumps, valves, exchangers.
Find where the leak is by using heat sensors and stethoscopes where the leak might be and isolate that tube by plugging it off the manifold.The alternative is to rip up the section where the leak is and fix it.

it is always powered. Nothing to worry

If you want less trouble so repairmen don’t have to come to the house to clean sensors or replace expensive gas controls, get a standing pilot unit. They are about 5% less efficient, but you gain in not having expensive repairs or maintenance.

You might have problems with that D151 motor as it is listed as a 230 volt motor. You might not have a problem if you are in Canada with 230 volt house wiring.
http://www.fasco.com/pdf/p31.pdf
The white wire is usually the common ground wire for 115 volt houses; but would make no difference if the house is 230 volt.
The black, red, and blue are usually speed wires. I’m surprised there are no diagrams on the motor or on the paper that comes with the motor in the box to help you.
However, it is listed as a reversible motor, so you need to find how to do that as well. Unless someone just used that particular motor and has a perfect memory of it, you’d do best to call the place you got the motor from to get the wiring diagram before you play with it.

There isn’t a furnace or boiler made in 1955 that is worth keeping in these days of costly fuel. The unit has been throwing away at least 40% of the fuel for half a century.
If you want to fix it, it’s a good idea to give the make and model instead of just the serial number. You give no clue why you need a flue instead of just cleaning it up and tuning it up.
