Zina K Granbury, , TX December 06, 2015 Appliance: Samsung Microwave SMH7187STG/XAA-0000 Samsung Microwave Smh7187stg/Xaa-0000 / : The handle on my samsung microwave door keeps breaking off. How to replace Microwave Earth Door Assembly. I took the vent off first and pulled the door off the hinges (so easy to do). Then took a very thin knife and very easily popped the plastic liner off and unscrewed the 2 screws for the handle. Then the broken pieces just came off. Then took the metal clip and put it into the new cap for both pieces and then screwed the handle back on very easy not to break the plastic. Completed so now I pit the door back and and screwed the vent back on TaDa! New Handle... It's simple to do. DIM (DID IT MYSELF) Zina K.
