You need to adjust it with a load on the system. Make the adjustment with the stove burning and WH on if you have one.Sorry totally forgot to include in my last post that I did verify gas pressure. I'm hoping I did it correctly: there was a port under the fridge gas control that had a nut on it. I unscrewed the nut, put my manometer on and turned the gas on to high and it was reading just over 12 inches. I adjusted the regulator and brought it down to 11 inches.
