CAN FURNACE BLOWER BE REPAIRED???

you could try with power turned off or call an a/c repair person to remove rag. good luck!

Use a vacuum cleaner, the small round end.

Check the main blower. Make sure there is no debris stuck in the fan wheel( squirrel cage) or the blower as this can cause the blower to be out of balance and vibrate. Also check the blower wheel for any up and down or sidevto side movement which could indicate a worn motor bearing. Hope this helps.

you may have to replace the blower because the squirrel cage is out of balance due to the loss of blades.
and may have damaged the bearings/bushings
if you can get just the squirrel cage that great

More than likely the squirrel cage blower motor is defective or the blower cage bearings are in need of replacement.

This is for the main blower right? if so...

You'll want to have the replacement parts around for this, usually the only thing to break is the motor, but occasionally the squirrel cage will bust up.
First unplug the unit, then proceed to disconnect everything in the path of the blower assembly. Take note of exactly which wires go where and whatnot (taking a picture is a good idea).
The assembly itself sits in a track and is held in place by 2 1/4" hex head screws. remove those then slide the entire assembly out of the unit.
Loosen, with a small Allen wrench, the little screw holding the motor shaft to the squirrel cage.
The motor is held to the assembly with a few bolts, easy to spot, they should be 7/16th hex heads.
Remove those completely, undo the ground (green wire) then drop the old motor out of the assembly. This may be very difficult (Use the weight of the motor to your advantage).
If your squirrel cage looks fine (no broken pieces) then all you need is the new motor.*
You'll need the harness from the old motor, strap that on in the same position as it was on the old motor.
Slide the new motor into the assembly and bolt it in with those 7/16th heads. then position the squirrel cage on the shaft in a way that it rotates freely and easily, as centered as it can be, then tighten the little allen head... super tight, you don't want that to come loose.
Then slide the whole assembly back into the furnace and reverse all that previous undoing.

*If the squirrel cage needs replacing, remove the old one (it'll just pull out once you've undone the motor and a few small screws) slip the new one in, and continue.

If the wires from the motor seem confusing, green is the ground (put a loop on it and screw it to the assembly), the rest go to the circuit board. White is Neutral, Red and Yellow are spares, Black goes to "Cool" and Blue goes to "Heat". I can't remember the name of those types of plugs, but they're often available at auto parts shops. You want the 1/4" size. the neutral may be the 3/16" or 1/8th size.

The first thing I would do is to clean motor and squirrel cage. It would be best if you would remove it and take it somewhere that you had a air compressor to blow out motor ports and fins on squirrel cage. Most of the time you can remove by disconnecting modular plugs and removing two or more screws on rail that squirrel cage slids on.
If you can get it out you can use a fine wire brush to loosen dirt and dust from fins on cage then use air to blow out as much as you can.
Your motor may be getting worn so check the bearing by grasping cage and see how much it will slide side to side and if it moves more then about1/8 inch then you are going to need to replace it before much longer. Also make sure that the rim of squirrel cage is not rubbing on blower housing and if it is then loosen motor mounting screws and adjust ,then retighten screws.
I hope this helps you. Thanks

The best way to really clean the squirrel cage is to remove the entire indoor blower motor housing assembly out of the furnace then remove the squirrel cage from the motor shaft and pressure wash the squirrel cage. Make sure you don't use to much water pressure as you might knock off any balancing weights that may be attached to the one or more of the vanes. Make sure the cage is completely dry before you re-install it back on the motor shaft.

The A/C evaporator coil ("A" coil) has closely spaced fins and those fins are easily clogged, which severely restricts airflow for both cooling and heating. Look at the fins on your blower wheel ("squirrel cage") - if they are dirty then so are the fins in the evaporator coil. Access is a pain, sorry. Disassemble and clean from the bottom/inside.

If the blower is made of plastic it does not have a set screw. You most likely need a new squirrel cage. They are formed to the shaft and have a compression ring that holds them in place.
