How to check a refrigerator compressor

In a cooling system like AC, Fridge, Freezer, Chiller, Show case etc. The compressor is a vital component that serves to circulate the refrigerant gas. if the compressor is corrupt, the owner generally reluctant to replace it with the reason the price is quite expensive, 1 door refrigerator compressor price alone could be priced not far adrift with the purchase price of a used refrigerator that is still worth taking.
There are several types of damage that can still be improved on these devices such as damage to his electro motor windings and mechanical damage, damage rolls would be rewound while for damage
mechanical like pistons, reed valve etc, unfortunately for the small size compressor no new parts are sold, so we can only replace it from another compressor copotan results, to repair the damage before we have to divide the compressor and must be done carefully and clean .
If one day your refrigerator experiencing the unexpected, better listening tips from me on how to check the condition of the "health" of your refrigerator compressor, in case helpful.

Checking electro motor windings in the compressor:

     Let the refrigerator in a state on, prepare major appliances such as screwdriver, pliers, Multitester and if there is a clamp meter.
     Setting clamp meter (commonly called tang amperes) at amperage measurement position, tuck the cables connected to the overload switch into the ring clamp meter and note the results of his measurements should be lower or the same as the data written specifications of the refrigerator plant earlier, for example when writing "current : 0,6amp "then the measurement results should be the same or slightly lower but if exceed please check first whether the mains voltage as needed (220v) or not, if the sound generated is more rugged compressor can result in a measurable increase in ampere.
     Setting multitester on the position of the AC current measurements, with pen measuring multitester connected to the floor first and then the other to the compressor body (make sure the compressor gets baud suppose unpainted ground in the compressor or its copper pipes, see if there is voltage measured in the multi-tester results of step earlier, if there is no meaningful rolls in good condition

Checking electro motor windings in the compressor section 2.

     turn off the refrigerator by pulling the plug from the socket
     open the socket cover electric compressors that are usually on the left or right side of the compressor (see picture)
     disconnect and overload relay from its socket.
     setting on the multi-tester ohm meter position.
     paste into the body of the pen multitester compressor and the other 3 pieces connect to the socket located on the compressor, one by one, if there is no resistance at all three sockets this means that the measured electrical compressor motor is really in good condition.

Checking electro motor windings in the compressor:
Still on the to 3 Pin or socket located on the compressor and a multitester on ohm meter position, the third measure this socket in a way to overload the socket plugged into a mains socket or socket eg C (usually be at the top or bottom / side by side is not) associated with the socket S and then C again with R, from the results of these measurements should be obtained resistance between 15 to 25 ohms for the measurement of C (common) with R (running) and 20 to 40 ohms for the C (common) with S (start), if the results measurement is 0 ohms means the winding / electro motor windings short-circuit / broken.

Note:
Use footwear and gloves are dry when you want to do this job.
Benchmark measurements presented especially for refrigerator compressor 1 door / under 100 watts.
