It depends on the noise. If it is a squealing noise it is probably a loose belt and needs to be replaced. Check the back of the belt if it is "glazed" meaning slippery and shiny then replace the belt.
Loose, or worn out.
What you are probably hearing is the flame, it is normal for the burner to make a whooshing noise while it is on. If the dryer is making a squeaking noise then it probably needs a belt or bearings.
Possibly and it can be the drive belt making a noise. It you hear a whine it is likely the alternator bearings are shot. You can remove the alternator and have it tested at most auto parts stores, after you make sure the belt is good.
They make noise by making it.

check the belt and make sure a bollet is not jammed
it could be belt pulley rubbing on the timing belt cover or it could be the berries in the wheel but if its making grinding noise while ilding then def check your pulley make sure it isn't rubbing on anything or it could be the flywheel theres numbers of things to check over for the grinding noise
front of timing pulley making rumbling noise took belt off and still making the same noise.is the timing chain are is it a bearing on pulley.
iwhat does the noise sound like. most likely a worn belt or belt tensioner if its a high pitched squealing noise.
My car, a 2008 Audi A4 Turbo was experiencing a cyclical chirping noise, similar to a noisy fan belt ( which it does not have). A defective PCV valve was found , however, the car after being repaired is still making that noise.
1) Replace the belt or make sure it is tight. 2) Replace the AC compressor.
Is it serious if my car idler is making a noise?
