Hello Kmewers,
We appreciate you sharing your experience with our Samsung - Flex Duo™ 5.8 Cu. Ft. Self-Cleaning Freestanding Gas Convection Range - Stainless steel.
Regarding your question, does self-cleaning the Oven makes a buzzing sound?
The buzzing sound comes from the relays located on the control board. Remember, the Oven gets very hot during self-clean, so the control works at full speed to get all the elements working.
