We have SAMSUNG Household Gas Range (Free standing) built in 2020. 

When we start the oven to bake/roast something, I can hear the sound of gas flow, and and see the glow of the flame. as it is heating, every 10 to 15 seconds, the "gas flow" sound stops, and we hear what sounds like it "re-lighting" and the flow sound returns. This goes on as long as the oven is warming to the set temperature. We observe the glow of the flame without any apparent interruption while this is going on. 

There are no error codes being presented, 

Is this normal behavior that we just failed to notice until recently? or is this something that requires attention?
