Display shows a lid-related message (e.g., "LID" or flashing lid icon) and the cooker will not start; some Aroma models beep continuously until lid is closed correctly.

Safety first: Unplug the cooker before manipulating the latch mechanism.

• Check lid closure: Open and firmly close the lid several times. Ensure it clicks into place and the latch fully engages.
• Inspect latch area: Look for rice grains, food debris, or dried sauce around the latch and hook. Clean thoroughly with a damp cloth and a small brush.
• Test switch actuation: With the unit unplugged and the outer cover removed (if necessary), locate the lid microswitch near the latch. Manually press the switch lever and listen for a distinct click.
• Adjust hook: If the lid hook is slightly bent and not pressing the switch, gently bend it back so it fully depresses the microswitch when closed.
• Replace microswitch: If the switch does not click or remains open/closed regardless of position, replace it with a similar rating microswitch used by Aroma.
• Re-test: Reassemble, plug in, and verify that the lid message clears when the lid is closed.
