The compressor is trying to start and cannot because it is broken inside and will need to be replaced. The compressor can be replaced by most anyone that is familiar with working on home central air conditioning units. I have replaced a few compressors for units like yours. Have a professional check it out. It could just be the start capacitor, but usually it is not.

Constant clicking sound coming from power box amana fridge

When you heard the click and the compresor stops ,check if it's very hot , if yes the compresor is of on overload and this could happend because 1 the condenser coil is dirty ,2 the relay is bad or 3 the compresor has a problem .Also check if behind the kick plate there's a timer (some units have it there or next to the cold control ) that could cause a problem too.

Air conditioner fan comes on then surges for compressor and stops

You can check if theres power to the compresor by pulling the wires off it and turn it on with the volt meter at its terminals if there's power the comprresor is either burned out jamed or grounded.

The condenser fan runs, 30 second later the compresor kicks in then 20 seconds later the compressor turns off while the condenser fan is still running

You have either a bad overload/relay or a bad compressor . Remove the o/r from the compressor and make sure there is continuity between all 3 terminals . Also check from the terminals to a copper line to make sure there is no continuity . If ok , then replace the o/r and check the amps from a wire to the compressor . If high amps ( 2.7 or higher ) then compressor may not have long left .

Freezer or fridge stopped cooling. Can not hear compressor kick on

If the compresor is trying to start and it won't you 'll heard a click and the compresor will be very hot ,that means that the relay is bad or the compresor is stuck or burned and needs to be replaced, but first before replacing the compresor try with the relay (no more than $20).But if the lights and fan inside the fridge work and the compresor won't start and is not hot ,the problem is in the cold con trol (you can put a jumper wire between the two wires to the cold control and if the compresor starts thats your problem) after all this if still the compresor won't start could be that the timer is stock in the defrost position.

Gurrgeling noise after compressor kicks in

The sound that you are hearing is the refrigerant moving through the system. That can be a very normal sound. If you are not experiencing any other issues I think it is ok.

I can't believe that just sitting in a box can harm it. If it was stored in an upright condition, you should be fine. The system has oils in the compressor. So if it was stored upside down or something then the compressor could have run dry. This is usually ok if the unit returns to an upright position for a day or so before it is run.
