Question

The refrigrator is a Kenmore side by side with icemaker, I am not sure of the model or the age as came with the house when I bought it one year ago. The noise is not constant but starts and continues for a couple of hours at a time. This happens 2 to 3 times a day. The noise is incredibly loud and sounds just like an airplane propeller. The unit seems to be working fine except for some icemaker problems such as occasional leaking water, and freezing up directly under the icemaker and above the ice storage bin. Are these problems related? Or is the noise my compressor?
