A:Answer Hi Kpark.
Thank you for reaching out regarding your Samsung - 6.3 cu. ft. Smart Freestanding Electric Range with Flex Duo™, No-Preheat Air Fry & Griddle on how I set Broil to High. I am sorry to learn you have a hard time doing it. Regarding your concern, here are the steps.
How to set the oven for broiling
1. Press Broil once for Hi or twice for Lo.

3. Press OFF/
