Blower Noise

Polar vortex hit us and my Rheem furnace blower fan started making a new noise. The noise doesn't appear right away but usually takes a while before it is heard. Everything still works fine. Filter is clean. I verified the there is nothing I can visibly see that is in the fan. Any other troubleshooting steps I can take or do I need to call in a professional?

Thanks.

Headphones were plugged in.

If it were a car I'd say a bearing!

Is there an easy way to verify? Is this something easy to replace? Instructions?

Pretty hard to confirm bad bearings. It's usually just by the sound of them. What will happen is they usually get louder when hotter and when they get noisy like that will fail shortly.
If you are very handy...... you can pull the motor out and replace the bearings.
Otherwise.... it's easiest to replace the motor.

Thanks for all the info. I haven't heard the noise for a while so I'll play it out and see what happens. I have space heaters and a dual zone home so I should be ok if it does go out.

Odds are it wont fail catastrophically.

Noise will simply get worse so you have your notice.

Pretty easy repair, just simple replacement of blower!

Good to know. Seems like I only hear the noise when the blower is on for an extended time like when we get below zero temps for a few days.

Thanks.
