Hi all. I'm a very, very inexperienced homeowner who's trying to solve a furnace fan problem.
Suddenly, my furnace fan has become very loud.
It's a Tjernlund SS1. It works fine but went from being mildly audible to sounding like a mac truck is parked and idling in my garage (my furnace is in my garage, no basement). It also seems to come on more frequently, although this might just me noticing it more because it's so loud.
So, I found this site:
Which seems to have all the parts I'd need to try and resolve this. My Question is, what parts do you guys think I would need?
Thanks in advance to anyone who can offer advice.
