Im not sure how to ask questions on Hearth.com. I wanted to ask you a question. On Christmas my UVS27 stove worked. Today I fired up the pilot and waited to hear the familiar small clink noise that comes before I can turn the knob to run and have burner start but it never came. In NY we are in -20 windchill today and I was stressed for more heat. I never trusted the blade connections on the valve and loosened the screws to check for corrosion with no luck. I then moved the red wire to touch the TH connector just to see if could short a sensor and the stove started. I am not a stove guy but work with building systems and low voltage controls and thought I would try this. I want to fix it correctly. Does this call for a Thermopile. Thanks Johnnyh
