the motor could be on the way out. Put your hand (carefully) on the motor (back of the refridgerator), if it is too hot to touch then the motor is burning out and will need to be replaced.

Check the compressor mounts. They are usually springs mounted with rubber. If they are two loose the compessor wil hit some other metal part when starting up. Shakle it and see what it is hitting. Ajust accordingly.

SOURCE: Knocking/banging sound on compressor start up

I have a GE ZIS480D - side by side with compressor on top. It had an even tempo knockng sound coming from comprssor area. I asked my repair guy (at his shop) wat it could be. He shruggs and says "dont know, I'll have to come out and see it for $65." Just give me an idea of what it might be. He says "could be the timer or the motor knocking on something. I'll have to come out and take a look".. I'm a very highend custom homebuilder and have built hundreds of homes with every possible issue imaginable. When a repair guy says "dont know need to see it" it means I have no idea but by the time I leae your house I'll come up wih something. When something doesn't make mechanical sense I just pound on it or give it a good smack. I do it with my truck, my computer, my doors that stick and even sometimes my wife (kidding about the wife, she'd take me out in a heartbeat. Anway, I got up in the compressor ares and smacked it a couple times from every direction and sure enough it stopped knocking. I have been called a genius before but all I do is force into submission and it works. A good smack with the palm of your hand will not hurt the unit. Give it a shot

SOURCE: GE Profile making knocking noises at different times

I have the GE profile Refrigerator with ice maker in the refrigerator compartment. Mine was knocking loudly for long periods of time, so I finally removed the icemaker by removing the side panel in the icemaker compartment held with 1 phillips head screw, disconnecting the electrical plug (unclip), pulling the tab of the icemaker down (on top) and sliding it toward the door, thus removing it. There was ice frozen in the motor compartment that was the problem. I let it thaw out and re-installed. All was OK after that..
