Our refrigerator stopped working, compressor not kicking on.
The compressor is attempting to come on but fails.It starts off by making a long hum and shuts off with a click. The fan and light are working. We have cleaned the coils as suggested in the manual, but it did not do anything to help it. Is it possible that the thermostat is going out? Our refrig is only 2 years old. We bought it brand new when we bought our house. What can we do to fix this problem?

If the clicking is right at the compressor, there is an overheat switch there. If the compressor is not humming normally, it may be the start capacitor, or the compressor itself. Check for dust buildup on the coils, that will overheat the compressor, same for a fan that is not working.
Hi David and welcfome to FixYa. I am Kelly There are a few things to try before you go replacing parts.
1. after the unit has sat with no power for about 30 minutes plug the unit in and listen for an attempted sart on the compressor. An attempted start will only last for approximately 40 seconds. During that attempted start listen to see if you actually hear the compressor turning. If you hear it turning and it again shuts off wait another 30 minutes and try it again. (On a unit that has been in storage for more than 6 months it can take a few attempts to get it going.) If it just hums and does not move then your compressor is locked and as it attempts to start you will notice a slight dimming of the house lights. Don't give up on it right away... do about 4 cycles of the plug it in.. listen for the 40 seconds then the CLICK of the compressor thermal overload switch. If your not hearing a CLICK after 40 seconds or so then there can be a compressor PTC relay / thermal overload (KliXon) problem or the possibility that the run capacitor has failed. After all of these have been checked out then you start looking at controls and power. Give it a few more tries to see if it takes off. If it does not then just repsond here and someone will help you.
This sounds very much like a compressor failure. unplug the refrigerator and check the condenser for cleanliness. After cleaning the condenser and allowing the compressor to cool, plug it back in and listen for the same sounds. If the compressor was overheated it should restart after it cools. If it does not restart the compressor could be seized. Check the compressor warranty against the age of the refrigerator.
It is the compressor that has failed. The hum is it trying to start and the following click is the overload protector opening. What is the temperature where the refrigerator is located? Allow the compressor to cool down before trying to restart it. If it still does not restart after it has cooled off it is done.
It sounds like the ice maker. If you don't have the water hooked up, and the ice sensor bar is in the down position, the ice maker assembly will attempt to make ice continuously. Solution is easy: raise the ice sensor bar until it clicks in the up position. It will lock in this position, and the ice maker will not cycle anymore.
It looks like the Capacitor Start Relay is failing. It is located either on the starter Relay or mounted on the side of the compressor compartment. It sould have two wires on it, one orange and the other probably white.
