The long metal thing is the temp. sensing element. It senses the temperature and sends it back to the metal box. If you are feeling adventerous you can pull it straight out. It's only about 9" long. It slips in as easy as it slips out.
Slightly
This sensing element contain a small refrigerant charge that expands and contract based upon temperature. This force acts upon a small bellows attached to a switch in the metal box. When you turn the dial you are changing the amount of force needed to be applied by the sensing element to trip the switch and send power to the compressor.
Even more
If the sensing element gets broken or kinked - It is tagged and bagged. Need to get a new one.
Warning:
Stated for the obvious.
110V is dangerous.
