Electrolux, headquartered in Stockholm, Sweden, sells the Frigidaire brand of commercial and residential appliances. Frigidaire offers different types of refrigerators, including counter-depth, side-by-side, French door and top-freezer refrigerators. Usually, a noise in your refrigerator only indicates a minor problem. If you do have a major noise issue with an interior component, it may indicate something more serious. Contact a refrigerator service technician for assistance.
If your Frigidaire refrigerator is vibrating, see if it's level by placing a bubble level on top of the fridge. Check the level of the refrigerator both side-to-side and front-to-back. If it's not level, pull the fridge out and see if the floor beneath it is level and stable. If not, fix the floor before pushing the refrigerator back in place. Or, use wood shims to lift up the lower end of the refrigerator.
Bottom of the Refrigerator/Normal Sounds
Check the drain pan if you hear a noise at the bottom of the refrigerator. Water dropping into the pan is normal. If the pan is rattling, then it's not secure. Use duct tape to attach the drain pan to the refrigerator and to keep it from rattling.
Your refrigerator normally makes a certain amount of noise in normal operation, including buzzing, air movement and humming sounds. Your evaporator makes a gurgling sound, and the defrost heater produces a hissing sound.
Your Frigidaire freezer has a circulating fan. The location of the fan depends on where your freezer is located. For example, if you have a top-freezer refrigerator, the fan is located on the rear wall of the freezer. Use your manual to locate the fan. A squealing or groaning noise from inside the refrigerator indicates that the fan is either rusty or has broken components. In those instances, it's highly unlikely the fan can be repaired, so you'll have to replace it. Contact Frigidaire to find a local replacement parts seller. A Frigidaire icemaker motor may make a loud noise when the motor is breaking down. Turn off the icemaker, and contact a service technician.
Rear of the Refrigerator
A noise at the back of your refrigerator likely means that you have an issue with one of three major components: the condenser fan, compressor or defrost timer. The condenser fan is located behind a panel. It can make a squealing or knocking noise. Unplug the refrigerator before attempting to open up this panel. Examine the fan, and clean it with a brush if it is dirty. If it's not dirty, it is likely defective, and you should probably replace it, since it's highly unlikely that you can fix it. If the other two components are making a lot of noise, you may have to replace them as well. A Frigidaire compressor often makes a humming or buzzing noise when not working properly. Repairing a compressor is complicated and almost certainly will require a technician. Replacing the compressor is expensive, and it may make more sense to simply replace the refrigerator.
