Question

My GE microvawe handle broke, I glued it, soon it broke again - this time with the door frame. GE offers a new door assembly for $215 (delivered) but we no instruction how to put it on. Is there a better solution than to buy this expensive part? If not, can I install the door myself?

Thank you for your reply.
