Hi, my Jotul gas stove has worked perfectly for many years of seasonal shutdown and restart. This year the gas was not getting to the burners so I cleaned my stove and cleaned the oxidation on the Thermopile. I started the pilot light and let stand for 10 minutes before adjusting the thermostat to start it up. It worked, my burners lit up and everything looked great for about 10 minutes when all of a sudden it just shut down and cut off the gas including my pilot light. My unit is a Jotul DV400. Can you try to help me? Thanks, Brian
