Why does my GE fridge make a clicking noise?

A GE residential refrigerator making a repetitive clicking noise is typically experiencing an electrical issue within its compressor start relay module or a mechanical fault in its automatic icemaker assembly. If the rhythmic clicking sound comes from the lower rear service compartment, it indicates that the compressor start relay and thermal overload protector are trying and failing to engage the compressor motor due to electrical wear or overheating. If the clicking sound comes from inside the freezer or fresh food section, it is usually caused by an electronic control board relay switching erratically or an icemaker water fill cycle stalling. You can troubleshoot by listening closely to isolate the sound location. You can verify that your corrective action is successful when replacing a faulty compressor start relay or servicing the icemaker eliminates the clicking noise.
