My refrigerator stopped cooling and the overload relay/capacitor made a loud humming sound every few minutes then shut off. I replaced the overload relay/capacitor and the fridge worked properly for a few hours until the internal temperature of the refrigerator hit approximately 46 degrees. Now, the same humming noise is heard, and the fridge is, once again, not cooling at all. The overload relay/capacitor can still be heard every few minutes, but I don't know/think the compressor is working.
I turned off and unplugged the refrigerator overnight. It started up fine again, but when the temperature gets close to cold enough, it makes the same sounds and won't cool any further or at all.

If the humming last 3-5 seconds then makes a faint click sound and stops humming for a minute or two. Then resumes the hum again it may be your compressor locked down. Stuck. Most likely it is just a bad start capacitor not kick starting the compressor. A $6 part.
Might be the compressor relay is fixin to depart this life. If this relay starts sticking all the windings will remain active and overheat the compressor. The overload will tae notice and shut the whole shebang down. Once it cools and makes contact the circus continues until the relay finally disintegrates. The last death throws will be a constant clicking followed by noticeable cooling loss in the ice box.
Probably not. The compressors are very sturdy and long lasting. The compressor is controlled by a start relay, and is protected by a thermal overload. It sounds like your start relay is bad, which would explain the buzzing sound. It takes a certain amount of time to cool down, and then tries to start again. The start capacitor and start relay should be replaced.
Many times a freezer and/or refrigeratordo not work right because of a dirty condenser coil...there are also many otherthings that can go wrong.
If you are hearing a clicking or buzzing then check out thelast two tips.
If your refrigerator is running but warm, then...
Check out this tip that I wrote about that... it is a great place to starttrouble shooting your unit...and something that you can do rather then callinga repair person to do a simple thing for you...
If it is the compressor making that sound,The compressor is bad.
A fan motor can as make this type of noise as well when going bad.
If it is the fan motor stopping,this will also shut the compressor down,due to the thermal overload protection.
