How do you validate the compressor, protector and relay of the refrigerator with a multimeter?

Answer:

Can be used to determine whether the compressor compressor broken phase: the resistance between the three terminals in dozens of Europe, indicating no broken phase. If there is a local short-circuit, the general meter can not be measuredOverload protector: the normal temperature overload protector is connected, and the resistance value is 0. But after the temperature rise, the electric shock can be broken off, and the resistance is great, it is goodThe relay should be called launcher: many types, whether it is a basic principle is to start at the moment, connected to the starting winding, now more of the PTC, room temperature measuring resistor in dozens of European or larger, are normal fault.PTC often appeared to be broken.
Ordinary compressor three pile head ABC, respectively, A-C + A-B = B-C, resistance is generally a few ouThe overload protector is a pull in statePTC is usually 9 to 22 euros, but some larger ones, like the MeiLing Athena series, have a resistance of 1 points, a few KPTC has a tip, drop it, get it in your ear, and listen to the sound of broken pieces
The compressor is referenced to the fan circuitThe protector is closedPTC starter 9~22 ohm
