The fridge is cycling about every 3-5 minutes, the relay on the compressor clicks but the compressor does not run, the click lasts about 5-10 seconds and then shuts off. the compressor never comes on. ECM motor is running and it appears in side fans lights water disp etc is working fine.

Yes you have a bad relay on your compressor.Remove the rear panel and take off the relay on the compressor shake it.If it sounds fried then you need to order new on .Just give your model# to your local parts depot and ask them to order you a new compressor relay hope i fixya:)
wihtthe modle number you can look up a part, try replacing the overload/relay( starting device) for compressor, may be bad compressor( in which ase youll need a professional) but the overload relay you can do yourself for about 60-75 bucks
I note this is a very old post. The compressor is not starting and what you were hearing was the PTC relay energizing followed by the KilXon thermal overload kicking off the compressor start sequence. What happens is that the PTC relays sometimes get a heated contact. Due to the weakened state of the contact it can cause a buzz. Even with a goo PTC relay you would hear the compressor buzz if it was not starting. In that case the run capacitor may have failed or the compresor rotor is internally locked at which point the start cycle will repeat every 3 to 4 minutes as the thermal overload cycles and the compressor will not start.
If the compressor starts and runs for a few seconds it could be the relay. Or it could be the compressor itself has failed. When a compressor starts and runs for a short period it is possible that the relay contacts are arced together which would have both the start and run winding in the motor engaged at the same time for more than 3 seconds. This would result in the compressor tripping out on the thermal overload. It depends on what type of relay your compressor has. If it is a thermal relay, unplugging the refrigerator for about 15 minutes would allow the relay to cool off and reset.
If the compressor tries to go on every two minutes, then the relay is functioning.
1. If the compressor has failed, it might be getting hot and tripping the thermal overload to shut itself down. It will cycle like you say and will be unable to cool the fridge.
2.It's also possible that you have lost refrigerant from the system. When the compressor goes on, the pressure drops below a threshold value. The system sees that there is not enough pressure, and shuts down. Once the pressure rebuilds, it tries again.
3. If the fins in the rear of the fridge are clogged with dust/debris, the system will not be efficient enough to cool. I doubt this is the case as the compressor would generally just stay on for a long time... longer than 2 minutes.
Try turning the thermostat to the coldest setting possible for both the fridge and the freezer. If the unit still cycles off after 2 minutes, consider repair.
Yeh The klixon relay is not at fualt its the compressor im sorry to say that in my opinion that the compressor has failed.
the clicking sound is the compressor trying to start but inside its all burnt out and jammed.. If you need any more help or adivice then dont hesitate to ask
