I need a schematic for an over the range microwave door in order to replace the handle. A samsung model SMH7187STG

Normally You have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screw(s) you need to remove.

Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.

In some cases, you then have to gently rotate the handle to unlock it.

You usually get better search results by leaving off any dashes or spaces in a model number.

You can find helpful literature and exploded view diagrams with part numbers here and you can order parts from the Pros here.

It's almost certainly the primary interlock (top door switch).

See this file for details on checking and replacing door switches.

You can also see the video at our site, which shows you how to access the door switches.

We have the service manual for the model SMH7178STE here, which should be pretty similar. It will also help you with disassembly.

You can order new "cap handles" (the plastic parts that join the aluminum handle to the door for 3.99 each plus 8.99 shipping and handling at the Sears Parts Direct Website. The part number is DE67-00222C. When you have the parts in hand, open the microwave oven door. On the inside surface of the door their is a black plastic frame around the door that pops off easily (gently use a screw driver to pry up the door frame) so that you can have access to the screws that attach the end caps to the door. You will need to hold the remant of the cap handle (the part that is probably broken off even with the glass surface on the outside side of the door) still while you unscrew the screws. Once the screws and broken remnant of the handle caps are out, you are ready to put new handle caps on the handle, then put the handle with the new handle caps on the door. By the way, Samsung was absolutely NO help with this. The agent I chatted with denied that their were any reports of the handles breaking off, so I had to cut and past the postings about the door handle breaking off ON THEIR OWN WEBSITE under "Community Q and A" into the chat box -- still the agent did not acknowldege the existance of these reports...or the possibility of a poor design. I asked for them to send me a couple of the $4 parts as a good will gesture....got nothing but lofty words about Samsung commitment etc. and only a authorized technition blah blah, no action. All you need is a strong thumbnail, a phillips head screw driver, new handle caps.

The door handle can easily be replaced on MOST microwave ovens by removing the inner door panel that goes around the perimeter of the glass. The following link explains how to access and replace the door handle:

The average cost for a replacement handle usually runs about $20 - $40. Replacements (if required) may be purchased at the websites listed in the link I provided.
The door handle is a simple repair that can be done with the door in place, or removed. And, you do not have to uninstall the oven if this is an over the range model.

It would help, however, to know the number of the microwave oven you are referring to. All ovens are not designed the same and are assembled in different ways. What I have provided you with is the basic information that applies to most ovens. If you have any questions, please post back with your MODEL NUMBER and let me know. I hope this helps you.

Check out this door frame diagram, specifically number 1805. It clips on to the door frame. Remove it using a dull table knife or something similar (be careful not to scratch or break anything). You will then have access to the bottom screw.

.
The choke cover (or door gasket on your brand) will come out similar to the diagram shown below.

Then the hidden screws should be visible.
