Hey All. Just wanted to say thanks for the info.
I had the same problem and learned a little bit about furnances through my adventure
My motor was humming but did not seem to turn. So me and my dad suspected the motor and took it apart. It was definitly stuck. What happened was 5 of the plastic blades broke inside the motor for a reason that is unknown to us. We cleaned them out and put the motor back in and started the furnance. The motor was rattling like crazy. What happened was the blade assembly was now out of balance and was knocking on the walls of the motor assembly causing this crazy rattling. However the furnance still did not work.
We thought maybe we had two problems here and it being the pressure switch. We blew in it and it seemed fine (pop open and close). I even used a multimeter to test it and if it making a contact and it did.
So the pressure switch was not the problem.
We decided to bypass it and stuck a wire between the two wires going into the switch. What this does is basically makes the furnance think that the pressure switch is working, but now we had another error "pressure switch stuck closed". What i figured was that the furnance when turned on checkes the pressure switch and if it is closed (default is open) right away gives you the error code, so it doesn't get to the blower motor stage.
What we did then was turn on the furnance and then a 1 sec later connect the two wires. TADAA!! It worked. We heat up our home because we didn't want to freeze, but then the motor just gave up and was stuck.
I went out today and bought a new motor.
WOW they are over priced here in Toronto. Ridicoulous prices... some people want $475 plus tax for it.
I searched around and i was given a company that sells motor by a nice guy i called while looking for the motor.
The company is called Canada Motors. Great guys.
