My lovely stove self extinguishes after a random amt of time, there’s a few second no flames pause, then the flames pop back on with large orange flames, then settle back to normal. Twice the experts fooled around with it declaring it fixed. Friday night after the guy left it did it again….but almost immediately after clicking remote on it lost the short blue flames and then it popped on again… Fast forward it’s Monday ~ warming living room on ‘high’ for half hour…stepped it down to medium and alls good… but just now 30 min later stove is silent….I look and flames gone…then again the big pop back on….this was near 9k installation and very frustrated___ideas? TIA
