Product review (5 stars): Easy fix,  super value.
My neighbour  replaced their dryer because of a broken belt.  I just fixed ours for less than $10. Even if you do not consider yourself mechanically inclined,  this is really simple. Very easy to install.  If you have never changed a dryer belt before,  it will be helpful to go to YouTube and look up changing Whirlpool dryer belt.  It will show you what to do with the belt tensioner.  Whole repair will take under 30 minutes. It is helpful to have a second person holding the dryer drum in place while you work,  but not absolutely  necessary.
