When your Sharp microwave door won't open or close properly, inspect the door components in this order. The open lever is the most likely cause when the door will not release, so check for damage and replace it if needed. Next, inspect the door spring, which can break and prevent the release mechanism from working. A damaged door latch can also keep the door stuck, while a broken plastic door hook may fail to engage or release the latch correctly. If these parts are intact, check the button spring inside the door open button, followed by the button itself, which may have a broken internal component. These repairs can resolve a Sharp microwave door that won't open, a microwave door that won't close, or a microwave door latch problem. Enter your model number to find the exact open lever, door spring, door latch, door hook, button spring, or door button for your microwave. Most door repairs do not require removing the outer cabinet. If cabinet removal is necessary, remember that the high-voltage capacitor stores a lethal charge even after unplugging. It must be properly discharged before interior work, so use a qualified technician if you are unfamiliar with capacitor discharge procedures.

The door hook engages with the door latch to keep the door closed during operation. Since the door hook is made of plastic, it can break due to regular wear. If the door hook is broken, it won’t release the door properly, preventing the door from opening. If the door hook is broken, replace it.
For some microwave models, an open lever is used to release the microwave door. If the door won't open, inspect the lever for any damage and replace if necessary.
