So my 17 year old natural gas furnace began making a noisy sound sound when turning on. A google search reveals the induction motor is causing the noise. The noise continues while the gas flame is on. It happened for two days and then for a week the noise is gone only to return again. I suspect it is to do with the bearings/bushings for the motor. Should I wait until the motor is completely dead before replacing? Should I buy a furnace repair plan and hope the motor lasts for the 30 day waiting period?

Maybe you should just fix your furnace now.
It's giving you warning that it's going to fail soon.
BTW a furnace that is 20 years old is a candidate for replacement.

Don't get any repair plan. Just get a repair guy to replace the part. Don't get a new furnace until the spring or fall. Prices are much better then, as all the heating/ac guys are slow. If the rest of the furnace is in good shape, just keep it another year or so. Don't let the service guy sell you a bunch of crap about red tags and a new furnace. Tell him to fix the part or leave and call someone else who isn't a crook.
If your budget allows, you may be further ahead by replacing your furnace with a more efficient model.
If your budget does not allow it, and depending on your furnace model, you can search the net for pricing.
I replaced the unit on my furnace a couple of years ago. There are lot of videos on youtube that show you how to replace this unit.
Ordering the unit from the US is a lot cheaper than what you could end up paying for it in Canada.
You should do it soon as it can stop working any time and usually these things happen at the worse possible times.

Mine just started making this noise as well when the flame is on as you can see the flame + hear the electricity and I have a high efficiency furnace repalced in the past 4 years. Kind of sounds like an weird electrical induction noise. This also happens to my fan switch in the upstairs bathroom right above the furnace. Now this coincides exactly with the recent power outage of last Wednesday and transformer fires. Not sure if it is coincidence or something else like due to solar flares or something. Something funny happened and it is hard beleving it's all coincidence.
I had the same issue as you. I ordered a new inducer motor for my make online. Got it in 2 days and replaced it. Real easy to do .. 4 - 5 screws .. Plug it in and done.. Cost me a total of $200 with shipping.
Mine is starting to act up as well. Here's a couple of videos for replacement procedures.

Thanks for the tip - i'll look into the mounting bushing first. The noise has stopped again, and if it were the bearings, I would think the noise would happen continuously.
