My microwave door opens on both sides. I need to replace the door because it is cracked and falling apart. I purchased the replacement part, but for the life of me, I can not figure out how to get the old door off! I have searched and searched, but can't find any videos to help with this particular Kenmore microwave. Any suggestions? Now that I have purchased the replacement door, the local repair place will not do the work, unless I purchase the door from them. What??? I need to figure this out!

Thanks!
