Michael for Model Number GBD307PDT09 built-in double oven While reassembling the upper door, after disassembling to clean, I broke one of the two pieces of glass that are internal to the door (cannot be touched when door is assembled). I now see that the two panes of glass are different parts and I don't know which one I broke. I may have swapped their positons when reassembling - or not. Is there any way for me to tell which piece of glass I still have so I can order the right replacement?
Answer Hi Michael. The 2 -inner glasses are different part # . The one closest to the inner cavity is part # WP8300974 the inner one is 12" x 22-1/2 ". On some manufactures inner glass you can tell the difference by setting your ohm meter on 100,000 ohms and finding the side is that needs to face towards the inner cavity. The one that goes to the outer facing glass is part # WP4449263 it measures 12" x 22". They are heat tempered. Thank You. Read More... Answered by AppliancePartsPros.com | Thursday, February 9, 2012
