The inner door glass is broken. Your replacement part number AP3028564 does not have any dimensions in the description. What is the size of the replacement glass? Mine is 6 11/16" x 18 3/16".
Answer Hello Lynnartis,
Counting the one inch squares in the picture of the part, the dimensions are about 6 3/4 by 18 1/4. I'm sorry but he part you need for the model number you listed has been discontinued by the manufacturer and no satisfactory substitutions have been provided.
Oven door is completely apart,not sure how to put back together...inner glass had to be cleaned 2 panels.
Answer Hello Ash. The only instructions for putting back together an oven door is the same way it came apart. We do have a parts diagram to help you with the order of the parts. Here is a link for you. http://www.appliancepartspros.com/door-parts-for-whirlpool-werp4120pb2.html
