Furnace blower motor is stuck!!!???????????
I'm baffled because I used absolutely no force when I put the motor rear legs into the fan gearstick and now its stuck as if I weld it in here.
Anyone??????
Thanks!
Answers: I THINK YOU MUST MEAN THE BLOWER WHEEL WON'T COME BACK OFF OF THE SHAFT AND THAT MEANS YOU TIGHTENED THE SETSCREW ONTO THE SHAFT ON THE ROUNDED PART OF THE SHAFT--NOT ON THE FLAT PART OF THE SHAFT-----. THAT LOCKED THE BLOWER WHEEL ONTO THE SHAFT. HOLD THE ROTATING PART(CALLED THE ROTOR) OF THE MOTOR IN ONE POSITION AND TURN THE BLOWER WHEEL AND PULL HARD ON IT AS IT IS TURNED. DEPENDING ON HOW HARD YOU TIGHTENED THE SETSCREW AND DEFORMED THE SHAFT DETERMINES HOW HARD IT WILL BE TO PULL IT OFF WHILE TURNING IT. BUT IT WILL EVENTUALLY COME OFF AS IT WEARS DOWN THE DEFORMED PART OF THE SHAFT WHERE THE SETSCREW DUG INTO THE SHAFT..----"DO NOT DEFORM THAT PERFECTLY BALANCED BLOWER WHEEL---YOU DO NOT WANT TO BE IN THAT POSITION"
Not sure what you mean; but you can try jamning the motor and turning the adherent cage clockwise consequently counter clockwise and pull them apart at like peas in a pod time.
Be careful how you jamn the motor; you do not want to destruction the windings.
Take a good look at the devotee cage where on earth it attaches to the motor.
Does it look crooked.
If it is crooked, you will have a difficult removing the follower cage from the motor until it is straightened.
Good Luck.
I sounds resembling the motor shaft is stuck in the squirrell shut within, hammering to loosen will prob damage the motor bearing or damage the hanger-on. It would be difficult to deform the motor shaft however a burr / indentation from the set screw can mess stuff up if its secured on the round nouns that is why the flat nouns is there. (to prevent slippage & allow for the raise ring made by set screw)
The hollow collar on the fan might be deformed from over tightening though special.
If theres room a gear puller would help provided the set screw is loose. Example technique...sometimes warm a stuck nut with a torch will allow the nut to expand & the bolt to loosen, never roast a stuck bolt or it will expand.
Some how the blower hub turned on the shaft a loose set screw will raise some ridges and bind it. This is what I would do remove the set screw and spray some PB Blaster surrounded by the hole and the end of the hub. Let it set a while clutch a soft rod(brass) and strike the hub make sure the motor is screwed down.this some time breaks down the bind.If that fail you have an additional option. Free the motor and hold some one pull on it while you strike on the motor shaft again next to a soft metal rod smaller than the motor shaft its going to stress the fan enclose some what but it has to come past its sell-by date one way or another. Been nearby done that!
