Lid is difficult to close or feels like it is grinding or binding when turning to lock.

Safety first: Unplug the cooker before working on the lid mechanism.

• Clean hinge area: Open the lid fully and clean the hinge and locking lugs with a brush and warm soapy water.
• Inspect hinge pins: Check for bending or corrosion. Lightly lubricate metal hinge pins with a food-safe lubricant if recommended by the manufacturer (avoid oil on plastic parts).
• Check for warping: Compare the lid and body locking lugs for symmetry. If one side is visibly bent, the lid or body may need replacement.
• Replace damaged parts: Install a new lid assembly or hinge kit if mechanical damage is present.
