Possible Causes

Stuck touch key, Moisture on control panel, Faulty buzzer driver on PCB, Electrical noise affecting keypad

Safety first: Unplug before cleaning the control panel.

Step 1 – Clean and dry panel: Wipe the control surface with a dry cloth. Ensure no moisture or cleaner residue remains.
Step 2 – Observe keys: Check if any key icon appears pressed or unresponsive. A stuck key may cause beeping; replace the touch panel if necessary.
Step 3 – Reseat connectors: Reseat the keypad ribbon cable on the PCB.
Step 4 – PCB replacement: If the buzzer sounds randomly even with a new panel, the main PCB may be faulty and should be replaced.
