User Manual LG MS4296OWS NeoChef Smart Inverter 1200W Microwave Oven

This microwave does have a cooling function to cool the interior of the oven after cooking is complete. Hope this helps! Kind regards, Appliances Online

I have been through this manual and there does not seem to be an adjustment for the tone, not all brands are able to do this, its done to let you know that you have depressed a function as a warning and that the button selected was the correct button for what operation you are wanting to do

Thank you for this question about turning the sound off, not all microwaves are able to do this it's a safety feature to let the user know they have selected or pushed a button to bring this to your attention to what you have selected. if you are wanting to ask the supplier if this is possible LG customer care on their Freecall number is Ph: 1300-542273 i hope this information will assist you when shopping here with us at Appliances online.
