Most refrigerators have a thermometer inside that will show the temperature. If there is not one, most stores sell refrigerator thermometers.
It is a thermometer, and is used to show the temperature.
Analog thermometers are based on the fact that matter expands and contracts in response to changing temperature. This is able to show smooth variation because the expansion and contraction is distributed among trillions of molecules per cubic millimeter. Since the expansion or contraction of each molecule is ultimately miniscule, the accumulated effects are excessively smooth.
So that you know that they show the true value, and that the results collected with one thermometer can be compared with the result collected from another thermometer.
It is a simple device. A variable electronic resister, called a thermistor, is used and is on the end of the cord. The resister varies it's resistance value depending on temperature. The probe must be placed in the area (outside) where you want the temperature. There is a second one in the unit itself and will show the inside temperature.
When the temperature changes, how long it takes for the thermometer to catch up and show the correct value.

Nothing will happen, except the thermometer will show the fridge's interior temperature.

A thermometer measures the amount of thermal energy a material has. This thermal energy is related to the vibrational and rotational energy the particles in the material have. By using the thermometer to measure the temperature of a material you are, in effect, measuring the amount of energy the particles of that material have.

Correlation.
If both thermometers were at room temperature before you arranged them above and below the ice cube, then the one below should show a greater change, and sooner, than the one above. The ice cools the air around it, causing the air around it to become more dense than the air at room-temperature. The cool air then sinks, right past the lower thermometer.
