Product review (5 stars): 100" 5 groove belt for my Maytag LDE8624ACM dryer
It's the right 100" 5 groove belt for my Maytag LDE8624ACM dryer!  Only 1 month old (bag has mfg date).
  Bag is marked Whirlpool, B008YDSETE (newest #) & 00-WPY312959 (older #).
  Old belt (1997) markings are green stripe and "6 8129590".
  New belt markings are "6-3129590"  "30092B12"(?)  "100 0719"(?).  Last two not very clear.
It's rolling the drum just fine.
