Hi, sounds as though the compressor is going off on its overload, which would be telling us that you have a internal problem in the compressor. The little black box you see on the compressor is the electrical cover for the klixon over load and the start, run, and common terminals. When the compressor is working over time or locked up, this small round overload protector that is wired between the wire on the common terminal, through the relay and on to power. It will click on and off when the compressor is hot due to a problem. When you hear it click, you no its doing its job, but you should inspect the wiring behind the cover. On each side of the cover you will have 2-tabs that you have to squeeze in at the same time and it pulls straight off. They can be hard to squeeze. You can also use a long screw driver to push one tab in as far as you can, and it may pop out. I have done this before. Make sure the power is off. You can look at the 3- terminals to see if maybe one has burned off, causing the compressor not to start. They get hot and can burn off. To check the amperage of the compressor, you would need a amp probe clamp around type meter, digital, and to use it the compressor would have to be running to check the R. L. Amps. You can check the locked rotor amps with it clicking on and off. You would set it to amps about 20 or the next step up, and clamp it around each one of the 3 wires going to the compressor. You would check the reading on 1 at a time and write it down lets say the run wire is at 7.8 amps, the next is 6.4 and last is 9.3 amps. Look at the data plate to see what the r l a ( running load amps ) is lets say 12.9 amps, so your not over and will be good. You can check it for l r a ( locked rotor amps ) when it tries to start before it drops out have the clamp around one of the 3 wires and watch the meter when it tries to start, see the reading. If the data plate says l r amps are lets say 35.5 and your reading around that or a little lower or higher, you will no the compressor has had it. Its locked up. If this unit has a capacitor on it, some do and some do not, it will be oval and about 4" long with a couple of wires coming from the top. If it is leaking any kind of oil on it, or it is swollen if metal, this will need to be replaced and may just be the only reason the compressor will not start. Take it down to a appliance parts store and they can check the uf and microfarads on it. You may get lucky if it is leaking and the compressor may start after you change it. If you can, do these checks and keep me posted on the out come. Just take your time when removing any wires and draw a diagram so you will no where they go. Please let me know and please be kind when rating me on helping you. Thank you very much. The best of luck to you.
