Beeping continues after cooking is finished and does not stop as expected.

Safety first: If the beeping is continuous and cannot be silenced, unplug the unit.

• Step 1 – Panel cleaning: Wipe the touch panel dry and ensure no moisture is present.
• Step 2 – Power reset: Unplug for 5–10 minutes to reset the control board.
• Step 3 – Test buttons: After powering back on, test all buttons to ensure they respond correctly.
• Step 4 – Replace control board: If the buzzer remains stuck on or behaves erratically, replace the main control board.

Warning: Do not attempt to cut the buzzer off the board unless you fully understand the implications; it may affect other functions.
