A GE residential refrigerator producing a loud buzzing noise is typically experiencing an issue with its automatic icemaker water supply, a vibrating condenser fan, or a rattling drain pan. If the icemaker is turned on but the household water supply valve is closed or restricted, the electric water inlet valve solenoid will buzz loudly as it repeatedly attempts to draw water. Alternatively, heavy frost buildup on the evaporator coils can cause the spinning fan blades to strike the ice, creating a loud buzzing or scraping noise. You can troubleshoot by checking icemaker settings. You can verify that your corrective action is successful when opening the water supply valve, turning off an unused icemaker, or defrosting iced evaporator coils restores quiet operation.
