You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.
The output of the thermocouple is linear.
Sometimes it can take up to TWO MINUTES for the thermocouple to take effect ( proof of flame) If the flame does not stay on the thermocouple should be replaced by a qualified licensed plumber
The thermocouple generates a small amount of electricity when it is heated which sticks open an electromagnetic valve,If the thermocouple fails, you'll be able to light the pilot, but it will shut down when you release the button.They're easy enough to replace, and they're under $20.Remember, this is an electrical connection, not gas. You don't have to sock it down or use sealer.
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose

You should not paint a thermocouple.

Control valves do go bad, but not that often. The tip of the thermocouple is in the flame? Holding the pilot button down long enough for it to heat? Sometimes the first time you light it, it takes a little longer for the thermocouple to work. Good clean connection on the valve end of the thermocouple? That's all I can come up with at the moment.

Yes, thermocouple is used in fridges !
To create a thermocouple one needs thermocouple wire, a means of spot welding the wire, and wire strippers. A thermocouple is used to measure temperature.
The thermocouple keeps a gas pilot light burning.
is a thermocouple an active or passive transducer?-why?
it should be pretty tight, but no so tight that it stretches it
It should be around 20 millivolts while operating in a flame.
