Refrigerator Compressor Not Running Problems and How to Fix it
There are many problem which may case of Ref or fridge compressor stop working, but i try my best to cover some most common reason. We will highlight it step by step....
Mostly compressor or fridge not working in case of no incoming power supply, for this issue first of all check your main distribution board to check breaker from which you get your supply for your refrigerator or for electrical outlet which is in used for your REF. If the breaker is in off or tip state then on it and if still it is trip again then check your supply line, may be a short circuit in your supply. Now if you switch on the breaker and breaker not tripping then check the outlet where your plug in the fridge plug, for testing the outlet (socket) the easiest method is that to plug in the plug of other electrical appliances (i.e example stand fan, set the knob of multi meter for testing AC voltage and insert the meter testing leads to the outlet.) Now if outlet have not receiving the power supply then change the outlet or fix the outlet problem. For that call a professional and if you can do this him self then do it but carefully. Here some posts which help you about outlets connection.

The other common reason of compressor not running is that your fan internally light will be glowing but your compressor will not working, for that i suggest you test first of all the internally thermostat that refrigerator thermostat is working or not working, As you know that thermostat is connected in series with compressor and supply goes through the thermostat, now if thermostat is stop working and making a open connection then how can the electrical supply will run to compressor. For that fix the refrigerator thermostat or change it.
In some cases, some one or mostly children move the thermostat knob on switching off direction, so first of all chick the thermostat switch and if this on off direction then change the direction of thermostat knob. One thing more that we use thermostat switch for regulating the temperature and if your compressor start only for some time and before to make ice , compressor is switch off, so in this case your refrigerator thermostat switch is on low cooling , for that do setting of your refrigerator thermostat for high cooling.
Capacitor is also one of the reason of refrigerator compressor not running. Some time we use capacitor with capacitor start relay which make a strong starting current for starting compressor. There are two types of capacitor which we use with refrigerator compressor with relay which are starting capacitor and running capacitor. And if capacitor not working then change capacitor with same type of capacitor.
