This DIY dryer repair guide explains how to replace a dryer blower wheel. The blower wheel is attached to the drive motor shaft. It spins to blow air throughout the drum and out the exhaust vent. If air isn't moving through the dryer, or if the blower wheel rattles, replace it with a manufacturer-approved replacement part.

These steps work for Kenmore, Whirlpool, Maytag, Amana, Roper, Crosley and Estate dryers with a lint screen housing located in the top cabinet panel.

Instructions

Do not proceed until you are confident that you understand all of the steps and are capable of completing the repair. Some repairs should only be performed by a qualified technician.

This video shows a gas dryer. For an electric dryer, skip the step for turning off the gas supply.

Step 1: Shut off the power

Unplug the dryer. If it's a gas dryer, shut off the gas.

Step 2: Remove the lint screen

Pull the lint screen out of the housing in the top panel of the dryer.

Step 3: Remove the lint screen housing screws

Use a Phillips screwdriver to remove the 2 screws that secure the lint screen housing to the top panel.

Step 4: Raise the cabinet top

To release the clips that lock the top of the dryer in place, push a putty knife under the lid near the left and right edges of the front of the dryer. Lift the top and prop it securely against the wall behind the dryer. 

Step 5: Disconnect the door switch wire harness

Use a slot screwdriver to release the locking tab on the wire harness plug for the door switch. Disconnect the wire harness. 

Step 6: Remove the front panel

Use a 5/16" nut driver to remove the front panel mounting screws from the inside of the cabinet. Pull the front panel forward slightly, and then lift and unhook it from the 2 bottom hangers. Pull the front panel off of the dryer and set it aside.

Step 7: Remove the drum

Note the configuration of the belt on the idler pulley and the motor pulley before removing it—you might find it helpful to take a digital picture of it so you know how to reinstall it. 

 

Push the idler pulley to the right to release tension on the drive belt. Pull the drive belt off of the idler pulley and the motor pulley. Pull the drum out of the dryer and set it aside. 

 Tip: Use the drive belt that you just released from the pulleys to lift the drum up and out of the dryer cabinet.

Step 8: Remove the motor clamp

Use a slot screwdriver to pry out and release the rear mounting clamp on the drive motor. Remove the rear clamp and set it aside.

Step 9: Loosen the blower wheel

Place a 13/16" wrench or adjustable wrench on the back of the blower wheel that's behind the drive motor. Place a 7/16" wrench or adjustable wrench on the flat portion of the drive shaft at the front of the motor. Rotate the drive motor shaft to the clockwise (the blower wheel is reverse threaded) while holding the blower wheel stationary to loosen it. 

Step 10: Remove the back panel

Lower the top panel and move the dryer forward so that you can remove the back panel. Remove the screws from the back panel. Remove the back panel from the dryer and set it aside.

Step 11: Remove the air duct

Remove the mounting screws from the air duct. Pull the air duct off and set it aside.

Step 12: Remove the blower wheel

Spin the blower wheel to the clockwise to remove it from the drive motor shaft. If the motor shaft turns with the blower wheel, hold the motor shaft stationary.

Step 13: Install the new blower wheel

Thread the new blower wheel onto the motor shaft. Spin it counter-clockwise to tighten it. Then use the wrenches to tighten the blower wheel on the motor shaft. To avoid overtightening the blower wheel, turn the wrenches until they stop and then apply moderate force to tighten the blower wheel on the shaft.

 Tip: While the cabinet is open, vacuum the dust and lint from inside the dryer cabinet.

Step 14: Reattach the rear clamp on the motor

Position the rear mounting clamp on the motor and snap it into place on the mounting bracket. 

Step 15: Reinstall the air duct

Push the air duct into place and line up the mounting screw holes. Insert the mounting screws and tighten them firmly.

Step 16: Reattach the back panel

Position the back panel on the back of the dryer. Line up the mounting screw holes. Insert the mounting screws and tighten them firmly

Step 17: Reinstall the drum

Lift the top panel and prop it securely against the back wall. Place the rear of the drum on top of the support roller that's on the rear panel inside the dryer cabinet. Lift the front of the drum to access the drive motor and idler pulley. Referring to the digital picture of the configuration, thread the drive belt through the idler pulley. Push the idler pulley to the right and loop the drive belt over the motor pulley. 

Step 18: Reinstall the front panel

Position the front panel on the hangers at the bottom of the cabinet. Line up the mounting holes and reinstall the screws in the top of the front panel to secure it to the dryer cabinet.

Step 19: Reconnect the door switch wire harness

Plug the wire harness back into the plug on the door switch. Make sure the locking tab engages properly.

Step 20: Reassemble the dryer

Lower the top panel and snap it into place. Reinstall the screws in the lint duct housing and reinstall the lint screen.

Step 21: Restore power to the dryer

Plug the dryer into the wall outlet. If it's a gas dryer, turn on the gas supply to the dryer.
