Removing the microwave door will allow you easy access to clean the inside of your microwave and can also allow you to remove all of the debris that might be built up around the hinges of the door. Most family microwaves get a lot of use because of the convenience, especially for reheating foods. For that reason, they tend to get a buildup of debris no matter how often you clean the interior. You may also need to remove the microwave door because it is cracked or has other damage and needs a new door installed. Be sure to use caution. Some of the parts of the microwave door are delicate and can be easily broken. Although the US CPSC has issued a warning against do-it-yourself repairs of your microwave, this is a reasonably safe repair, as you are not handling any of the electronic components of your microwave.
Step 1 - Unplug
For your safety, unplug the microwave before you start the project. Set the microwave on a sturdy flat surface, such as your table, countertop, or workbench. If your microwave is a model that is mounted into your cabinets or over your stove, pry the cover off of the front panel so that you are able to unscrew the mounting screws. Then, you will be able to simply slide the microwave out of the brackets. You can now proceed to the next step.
Step 2 - Remove the Cover
Remove the glass tray from inside the microwave. Using a flathead screwdriver, carefully pry off the plastic cover that is on the inside of the microwave door. Carefully work around the edge of the glass until the plastic cover is loose and lifts off. Some models of microwaves may also have a trim. Both the trim and inside plastic cover is likely held in place by clips. These clips are easy to break off, so be sure and have some patience when removing any plastic parts so that you do not break the tabs that hold these pieces in place.
Step 3 - Remove the Door
Next, you will remove the door. Open the microwave door as far as it will open. Pull the mounting pins out of the hinges. There will be hinges in both the bottom and the top of the door. You may need someone else to hold the door for you while you remove the pins. Having a helper hold the door in place makes removal of the pins much easier. You will then have two free hands with which to pull the pins out.
Step 4 - Replace the Door
To attach the door, you will follow the same steps, just as you did to remove it. Carefully press the panel into place. You should hear the snap sound as each clip snaps back into place. Do the same with the trim, if applicable. Next, you can put the door back on. Ask your helper to hold the door in place again while you align the mounting pins and slip them back into place.
