Compression, and adsorption refrigerators often fail due to the fact that they denied Electromechanical relays or breakers on the basis of the bimetallic plates. The first of them is used to trigger synchronous electric motors, serving a compression refrigerator system, and the second are the basis of the tracking systems and maintain at a predetermined temperature level freezer [1]. The reason for failure and the other is a burnout or a mechanical failure of the spring contacts in these devices. Ego especially applies to older models of refrigerators. And often you can see that, because of the insignificant, but hard to handle breakdowns (due to the lack of spare equipment) the throw is still quite usable machines.

Two LEDs with different color (e.g., red and green), you can build a simple indicator for voltages from 4.5 to 220 V. It is also able to determine the polarity of the source in the range 8-220 V. When measuring AC voltage, both diode glow, but if it is constant — lights one of them depending on the wiring polarity indicator. The scheme proposed by the Czechoslovak journal “Amaterske Radio”.
