Product review (1 stars): Doesn't Fit Maytag Dryer Model # MDET236AYW
The belt tensioner (only one groove, not two) is different.  Also, the drum guide wheels are too wide for the posts.  I don't know about the belt, but it seems to be a mute point in that the other stuff doesn't fit.  I should have taken apart my dryer before hand to inspect the parts before ordering this kit online, my bad.
