As with any product used, the refrigerator in use must be checked carefully before buying to prevent the production of refrigerants that may already be problematic. While there's no way to tell what a compressor looks like from the inside.
There are a few indicators to watch out for from the outside while getting commercial refrigeration gaskets. This is to prevent the high price you may receive for the device from being negatively impacted by paying a large sum for repairs.

There are three things that are most important when considering a used refrigerator such as:
Check the evaporator:- The evaporator is a box in the refrigerator that contains a fan. All parts must be secure and straight. Check drainage by pouring water into the drainage vessel.
The fan should work hard and not make any unusual sounds. All blades must look the same and must not have slots. Evaporator problems can also damage the compressor. The cost of a replacement evaporator is about the same as the cost of a new compressor.
Checking the cabinet:- Be sure to check the cabinet. If it looks old and worn, it's time to look for another unit. Make sure the door is tightly closed. Make sure the lights go out when you close the door.
Checking the condenser:- The condenser is the part outside the refrigerator where the compressor and fan are located. The compressor is black and has large and small pipes coming from it.
When the fridge is turned off, you should be able to gently shake the compressor back and forth. If unshaken, the shipping bolt may never loosen and the compressor will likely fail.
