Then it started making more noise. Noticed the blower fan had a wobble.
Turned it back on and listened to a horrible sound as the fan hub spun against the outer blades. 
My friend Jack ( my A/C heater guy ) was on a commercial call a couple hours away .
Looked up the part on Amazon and the freaking fan lists for almost $190.
Cleaned it off , grabbed some EvaDur welding rod and TIG welded the hub to the fan blades.( actually closer to brazing with that low temp rod )
It's working great and my replacement blower fan wheel ( $90 off ebay) will be here Thursday |
They call those a squirrel cage, and yes, they can go out of balance and self destruct. I did a couple of repairs on mine back in VA, but it was easier just getting the cage.
