My GE refrigerator is making a pulsating/vibrating sound (Fixed)

The usual rumbling of the unit should not disturb your attention, even the newest models are not completely silent. However, some sounds must alarm the owner and motivate to run a diagnostic. If your GE refrigerator is making a pulsating/vibrating sound and you notice that the unit isn’t cooling enough or there is an ice buildup on the back of the freezer, it is time to check the appliance. A GE refrigerator that creates unwanted noises in the night could be due to unleveled positioning. Aside from the assault on your ears, an unleveled fridge can also make the fridge work harder to maintain its temperature and create ice. Adjusting the rollers on the bottom of the fridge can fix the issue. Remove the grill in the bottom front of the refrigerator and use a wrench to adjust the wheels. Make sure the appliance can't tip forward and that the doors are completely shut and secure from swinging open. Turn the wheels clockwise to raise the refrigerator and counterclockwise to lower the appliance. Appliance manufacturers recommend that the appliance's front wheels sit about 1/4 to up to 1/2 inch above the back wheels. This also helps the appliance to run well and reduces the risk of the hulking beast from tipping forward. If you hear a short rattling, humming, buzzing or vibrating sound only lasting around 5 seconds about once every hour on a Bottom Freezer and Side-by-Side refrigerator with the XWF filter, this can occur if the ice maker is turned on but the water is not connected. The sound is caused by an isolation valve that is designed to help prevent major leaks from the filter. To correct this, turn the ice maker off until water is connected to the fridge. If this vibrating sound refuses to disappear despite all above troubleshooting, a defrost heater or thermostat might be faulty. To check the latter parts, request service ASAP.
