There is a start capacitor near the compressor that may be bad. If the capacitor tests OK then the compressor is locked up. A service man can try to get it going with a kicker capacitor but there is no guarantee that that will work.
If there's a buzz then a click it's your overload opening when the compressor doesn't start. Most domestic fridges do not have capacitor assisted start on the compressor, they operate on low back pressure starting. A hard start kit might temporarily solve this . Bottom line your compressor is on the way out.
ok ok ok,,,keep cool? try checking the drive motor it may have burn out or jamed up so wont be turning but it may be causing the humming sound you here,
Hi!!
It could be many things, the most common are Low R22 refrigerant, bad fan motor, bad compressor. obstructed condenser coil, bad starting relay, bad capacitor. among other things.
To check fan motor, set unit to HI Fan Only setting and let it run for a while, check that fan did not loose speed and it is not getting too hot.
If fan is OK, then turn unit to HI Cool 60-65 degrees and see what happens. Hear if compressor kicked in or if just made a humming noise and stopped. if this happens, replace capacitor.

It sounds like your unit is low on freon or the compressor is not kicking in. If the compressor kicks in you can hear it turn the unit on fan only or turn the thermostat off then turn the unit to demand cool you should hear a hum even vibration when the unit kicks in. If there is no audible hum ect... your compressor is probably not kicking in. The selector switch the temp switch the capacitor for the compressor or the compressor its self could be bad. good luck if you need to know how to test any of the above let us know
Try first replacing the relay(located on the side of the compresor)wich the part won't cost more than $20.If doesn't work the compresor is stuck or burned and you need to replace it.
about the only thing you can do here is take the back cover off the unit see if the cooling fan for the compressor is running if it is and there is an Indian on the compressor then the compressor should be replaced if the fan isn't running then clear the fan once its running then turn the unit off for 30 Min's and try again
