Question Furnace started making awful noise. See vid.

Hey everyone,

So the sound my furnace is making doesn't happen all the time. I KNOW i've heard it before but had completely forgotten about it due to it not making this sound all the time. In the video the sound had already been going for a bout a min or so before i started recording. 10 seconds after i stopped recording the sound went away and it was back to normal. The furnace ended up running another 5 times before i ended up leaving for work this morning and it sounded fine every single time.

Now the big question is, whats making the sound and can i do anything to fix it?

Normally i would just say screw it and call my local HVAC tech but i'm trying to avoid that right now for a few reasons and mainly money. 2017 has been a horrible year for my wife and I financially. It started earlier in the year with having to remove an $800 tree that took out my hydro stack that cost $500 fix. Followed by a month later my car died so i was forced to buy a new one (had been giving me problems off and on for a while each easily fixable except for the last problem) so a new car needed to be purchased, ka-ching$$ ka-ching$$!. Followed by a lot of dental issues with myself and my son who recently cost us $3000 to fix his teeth (bad genes in the family for cavities despite brushing and flossing everyday).

So needless to say i really can NOT afford to replace this furnace or spend hundreds on a service call and parts due to us already spending all of our rainy day fund money this year. So is there anything i can do to remedy this random sound that keeps happening? cleaning? greasing? or is it signs of something going to break eventually?

Please help , thanks guys!

Vid: sounds like its coming from the big black round thing in the middle of the video there. (i don't know the technical term, lol).

Is that the big round black object in the middle? the inducer motor?

Yes.

Post the model number for the furnace. It's not far from that blower on an ID tag.

So i found a few video's online showing how easy it is to replace these things. 4 bolts, unbolt pressure sensor, unhook electrical plug, unhook drain hose, unhook from exhaust pipe and pull out... is it really that simple?
