BRUSHES

Your 

CHALLENGAIR 2000XL™ 

has one brush-type motor. The brushes should be 

checked for wear after approximately 600 hours of use. If the carbon brushes are 

worn shorter than 1/4 inch, the brushes should be replaced. Brushes may be ordered 

from 

Double K Industries

 or an Authorized Service Center. Please be sure to specify 

that your dryer is a 

2000XL™

, as the brushes are slightly different from one dryer 

model to another.  

To check and/or replace brushes:

1.  Unplug electrical cord from wall outlet.

Disassembly:

2. 

Slide off the back cover from the dryer. This is a compression fit and will come  

 

off with a little effort.

3. 

Remove all screws on the outside of the dryer that hold the two halves of dryer  

 

housing in place. Lay the dryer on its side while removing these screws. Remove  

 

the O-ring on the snout of the dryer and lift the top half.

4. 

Each motor will be sitting in place inside the rubber silicone motor mounts.    

 

Removing the rubber silicone motor mounts from the motor is not neces- 

 

 

sary to replace brushes. The internal filter frame fits into slots on the inside    

 

of the dryer housing. This piece can remain while changing brushes.

5. 

Disconnect motor power wires (see wiring diagram). Note where wires connect.

6.       Motor: 

(a)

 Find the flag connector on the top of the brush assembly. There is a 

wire leading to this connector. 

(b)

 Place a flathead screwdriver with a fine tip 

between the flag connector and the plastic brush housing. 

(c) 

Rock the screw-

driver back and forth and gently wedge the flag connector out of the brush 

assembly. 

(d) 

Loosen  the  two  brush  assembly  retainer  bracket  screws.                    

(e)

 Remove the brush assembly. 

(f)

Replace the brush assembly with the new 

one, making sure that the small tab on the bottom is fitted onto the corre-

sponding slot on the motor frame. 

(g)

 Replace the brush assembly retainer 

bracket and tighten the screws which hold it in place. 

(h)

 Attach the flag 

connector  to  the  new  brush  in  the  same  position  as  the  previous  brush.                  

(i)

 Repeat these steps for the brush on the other side of the motor. 

Reassembly:

7.  Inspect the motor mount for cracks or damage -- replace if necessary.

 

Set the motor back into its original position in the dryer housing. The  

 

 

motor mount has slots that fit over corresponding alignment tabs on the  

 

 

inside of the dryer housing.  These slots and tabs must match up for proper    

 

fit and function. (Note: In the event that the motor mount is removed from    

 

the motor, simply replace it by being mindful to align the contours of the  

 

 

motor mount with corresponding contours on the motor housing.)  Make    

 

sure that the internal filter housing is in its appropriate slot before putting    

 

the halves together.

8.  Reattach the screws around the outside of the dryer making sure the two  

 

 

halves are matching up. 

9.  After the two halves of the dryer housing have been put together, replace  

 

 

internal filter and push the back cover onto the rear of the dryer. Always make  

 

sure all filters are in place before operating dryer. Replace o-ring on snout.
