Blower making noise

[Fishfan]

My AC blower suddenly started making a deep throated rumble yesterday. No bueno. Any ideas before I start taking things apart? Is there any routine lubrication or cleaning required?

Could be a leaf stuck in the fan.

Try running it on its highest speed for a couple of minutes, then turn it on low speed. If its a leaf it might break off, if it continues run awhile longer or remove fan motor. If its the bearings it will sound like mables rolling fast. If its a leaf type object it sounds like a card in you bicycle spokes.

I've had success with drilling a tiny hole in the end of the motor can where the bearing/bushing is and dropping a little lite oil in. It will usually quite down.

Make sure no critters have made a nest inside the basket, throwing off the balance of the blower motor. That makes a racket too.

MrC read my mind ck for a nest from critters

 

[Fishfan]

The culprit. A couple of pieces of insulation. Easy peasy. The only thing that was a b!t(h to do was unfasten and fasten the 1/4" sheet metal screws that hold the blower assembly in place. No easy access and the ring it mounts into is crooked. The top screw was halfway under the firewall edge.

Glad you got it fixed.

You should see how much of a PITA doing that on Formal. LOL!

I now have an access panel.
Broke my balls to have to do it but the next owner will be Thanking God like no tomorrow.
