Whirlpool Dryer Squeaking on Startup

[neustkg]

Model Number WED5100VQ0

I have a Whirlpool dryer that always sqeaks (very loudly) when starting up. The squeaking lasts for about 2 minutes or so until the dryer heats up then the noise goes away. This happens all the time now and the squeaking lasts longer when temps are colder outside. I haven't been too concerned about it as it always goes away, but I want to be ready to repair it if the squeaking eventually doesn't stop or if maybe the dryer stops tumbling. I figure it is either the belt squeaking or the pulley that turns the belt. Can anyone give me advice and where to get the part?

Likely an idler pulley going bad, but... your blower wheel should be closely inspected as well.

Not likely, but its likely The pulley that tensions the belt= the idler pulley as above

I ordered a maintenance kit a few weeks ago that included all pulleys and a new belt.  I replaced everything last week and noticed bits of belt in the bottom of the dryer (thought at first they were mouse droppings).  No more squeaking.  Was worth the $40 for the kit.
