Microwave door is difficult to open or does not latch smoothly; sometimes requires slamming to start.

Safety first: Unplug the microwave before adjusting door components.

• Inspect latch hooks: Open the door and examine the plastic hooks. If they are rounded, cracked, or worn, replace the door latch assembly.
• Check hinges: Verify the door does not sag and that hinge screws are tight.
• Lubrication: Do not use oil inside the latch area. If necessary, a tiny amount of food-safe silicone lubricant on hinge pins (not on latch switches) can help.
• Adjust latch bracket: If the door must be slammed to engage switches, the internal latch bracket may need slight repositioning by loosening its screws and adjusting.
