Still problems. Model 2190 Manual operation Propane refrigerator no circuit board. Thought I would ask the experts before taking this apart. Is the safety shut off valve serviceable? In case my description is wrong it is the part near the thermostat the thermocouple screws into. I checked the thermocouple voltage and it was correct. When the valve was working I could hear it snap closed when the heat was removed from the thermocouple. Now nothing. As soon as the manual over ride is released the flame goes out. Got gas otherwise. Anyone take this valve apart? Where I can I get another one if need be? nothing in the manual!
