How can you check the

How can you check the little units on the side of a small compressor on a refrig to make sure they are good. I know one is working it get hot and shut off the compressor when it don't want to start but what about the other?

Hi,
Really depends on the start relay and over load used on your compressor, and the make/model/style of your refrigerator....checking it for continuity with an ohm meter can help check/test them out. Does the compressor start? Does the compressor shut off on the overload/safety? An amp meter is often used to see if the compressor is drawing the correct amount of current/power or too much or too little. Many techs will just try another start relay/overload as a test if they suspect the old one is bad. http://www.applianceaid.com/refrigerator.html#clicking Ohm testing a compressor. http://tinyurl.com/36oh6 Ohm testing an old style relay.
