Kirby Lexan Fan is crack and need help to replace

POSSIBLE CAUSES: 1) Sometimes there is a piece of debris in the fan case. (Not likely, but possible) Take the power head, handle and cloth bag off of the Kirby, pick it up and turn it with the fan toward the floor and shake it to see if something falls out.

If there's nothing in there and it still makes the noise, you most likely need to replace the fan/impeller as it is probably cracked or broken. You can sometimes see fan damage by removing the power head, looking into the hole in the front of the Kirby and slowly rotating the fan by using the shaft in front. The damage can't always be seen that way, but if you can't see it, you'll need to take the fan case off so that the whole fan is visible to make sure. I have written complete instructions that should lead you through the whole repair.If neither of these things are found to be the case, check the carbon brushes. I don't have a guide written for this yet, but my switch repair guide (link below) will help you break down the Kirby to get to them. Unscrew both brushes, take them out and look at them. The remaining length of brush will pop out of the holder and if they are shorter than 1/2 inch long, I recommend replacement. (they are not expensive)
