When an RCA microwave door won't open or close properly, inspect the door open lever first. A damaged or broken open lever can prevent the release mechanism from working. Next, check the door spring, door latch, and plastic door hook for cracks, wear, or breakage. The door hook engages the latch to hold the door closed, and a broken hook may keep the door from releasing. If these parts are intact, inspect the button spring inside the door open button, followed by the button itself, which can fail because of a broken internal component. These are the most likely causes when an RCA microwave door is stuck, the microwave door won't open, or the microwave door won't close. Replace any damaged open lever, door spring, latch, hook, button spring, or button, and enter your model number to find the exact replacement part for your specific RCA microwave. Most door repairs do not require access to the high-voltage system, but any repair that requires removing the outer cabinet must be handled carefully. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged, so it must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, use a qualified technician.

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.
