Blower wheel how to take wheel off

In your instruction manual you should find a parts list, purchase a new blower wheel and install it. If it is an older unit it may be best to just replace it.

The entire blower and housing slides out you should find the mounting screws on each side of the blower housing they may be sheet metal screws either on the top or on the bottom. After you remove the two screws the blower should slide out. If you remove the blower wheel from the shaft make sure to tighten the lock screw on the flat side of the shaft. Another trick to pull the blower wheel from the shaft is loosen the lock screw and push the wheel in then clean the shaft wit fine sandpaper otherwise you can cause the wheel to jam up because dirt gets stuck between the wheel and the shaft

is one of 2 things you may have a piece of paper stocked in the blower assembly or you blower wheel is separating, you can check for any debris inside the blower wheel or check make sure the fins in the blower wheel have some play or you lost a balancing weight on the wheel is very easy to fix by replacing the blower wheel just measured the diameter and whit and go by your nearest WWGrainger and buy a new wheel will cost aprox. $50.00 to $70.00 if you have any questions please replay

Hope this help (remember comment and rated this).

Check for a loose set screw on the motor shaft for the blower wheel.
Check the blower wheel for a missing balance weight.
Check the blower wheel for a dust buildup in the blades.
Check the blower wheel for a broken fin blade.
Check the blower motor shaft for excessive play.(more than 1/4 inch of play).
Check mounting screws on the blower housing.

Remove the front face of the dryer and continue to disassemble the dryer until you have access to the blower wheel. The blower wheel is manufactured with a D shaped hole in the middle. If the whole on the inside of the blower wheel become rounded, then the wheel rotates at a different speed than your motor, causing the loud vibrations you have been hearing.

Using the pliers, remove the holding pin & blower wheel clamp. The clamp is the green ring and the pin is the small horse-shoe shaped pin with an arrow pointing to it.

Pull the old blower wheel off. You should see that the whole in the center is round rather than D-shaped.

Put the new blower wheel in place.

Replace the ring clamp & holding pin.

Re-assemble the dryer.
