Day & Night Heater Furnace Problem, No Heat? - bi metal pilot for janitrol furnace

Hello,
I forced one days & night air furnace, 510 Series If I move the configuration of the statistics, I can hear a click from the oven, but no sound of the burners to light a cigarette. The witness is always on, and you can hear when you move the statistics is the flame that had no gas, but through the burner. It is a metal (bi-metal?) Band / sensor, which in its second and call the connected metal band / sensor (a ceramic?) If two cables are plugged and screwed to it. I tried to ignore the connection via a cable directly to the two screws / connectors, but still no gas for the burner. (One of the cables went to the gas valve.) Was a medium and avoid correction of the strips of metal / heat sensor? Does this mean that the gas valve is defectivetion?
Thank you for your time.
Be careful ....
