Recently, there are times where the refrigerator will work just fine. But from time to time, for the most part, temperatures will get warmer and there will be a humming noise. I was told that the humming noise came from the compressor and was a sign of a faulty relay and capacitor. Therefore, I went ahead and changed both parts. It worked great for a little but now the problem persists. If I turn it off for a little, it will start working again for a while. What gives?

Sounds like your compressor may be going.

A couple things to check:
1. Make sure the condenser coils are clean
2. Make sure the compressor/condenser fan is running

I guess I forgot to mention that I've already taken both those steps. I highly doubt a compressor can go bad in around 7 years...I was thinking maybe it is a defrost problem?

Turning it off for a little (depending on how much time a little is) will not solve a defrost problem. To fix a defrost you have to let the evaporator coils melt off the ice.

The simplest way to check for a defrost problem is pull the evaporator coil cover and look at the coil.
If it is heavily iced/frosted up then it is a defrost problem.

You may havea low freon problem. You can tell this often if the evaporator coils are just frosty where the freon enters the evaporator coils.
