Dyson Makes a loud noise like something is impeding the

It might be the clutch. Mine did it because there was dirt stock in the end caps if the roller. Instead of the belt breaking a clutch kicks in and makes a loud flapping noise.

It is probably the brush roll motor making the noise. Remove the brush roll & belt and turn both motors on. If you do not hear the noise when both motors are running the noise is likely coming from the brush roll

Can you be more specific? "part left on the porch" Mine is having the same problem.

Try replacing the belts. Here are the belts you need:

Dyson DC14 Belts

You need to replace the belt. Here is a link to the manual and to the belts you need:

Dyson DC07 Manual and Belts

That is an indication that the belts are worn, stretched or broken. You simply need to replace the belt. Here is a link to the belt(s) you need and a manual you can view:

Did you check the roller brush to make sure it was clear of debris?

On a Dyson this engages the brush bar. Two possible faults: Debris (hair etc) caught in brush bar - cut out with knife. Or - damaged drive belt - pieces of belt striking casing. Last, but unlikely cause, debris in bearings of brush bar - replace brush bar.

If this is a Dyson with a protected belt that can't be replaced then it will have to be sent out to Dyson or get a Dyson servicepersonnel to check it over - protected belt motors are difficult to fix by yourself. If its clicking all the time, then it means the belt has to be replaced. In the mean time check that there are no obstructions on the beater bar and behind it and also check that the brush stop roller at the top of the hood is in the right position. It should move automatically when the handle is swung down in normal operation. 

Hi.

Check that brush roller (beater bar) is free to turn with no obstruction.
If it is still noisey after doing this try this site for Dyson repair manuals.
