How to Fix Fridge Making Rattling Noise Problem?
Rattling noise from your fridge not only produces due to one or two reasons, sometimes it may generate due to several different reasons.

At first, try to locate the source of the rattling noise you hear from your fridge.
If the noise comes from the bottom of your fridge, it may due to the misplacing of the drain pan of your fridge.
Placing of the drain pan at its previous position will reduce the rattling noise effectively. Rattling noise coming from the refrigerator backside, you need to check the defrost timer, the condenser fan, and the Compressor of your fridge.
If the rattling noise is due to the noisy defrost timer, most probably, you have to replace it. Ratting noise due to the condenser fan gives you some scope to resolve it.
Cleaning of the accumulated dust and debris in between the fan blades using a soft brush may repair the rattling noise. A too much noisy compressor is not any usual case.
It may happen if you have an old refrigerator with a too old compressor. Though replacement of the Compressor is too much costly, you have to do it in that case.
Rattling noise from the inside of the refrigerator may be for the inside fan that circulates the air into the fridge. Sometimes you may reduce this noise by simply shoving the light switch present in the fridge.

If your refrigerator has a condenser fan, it will locate at the backside of your fridge.
However, if you can be sure your condenser fan is creating the noise, you have to clean it properly to stop the rattling noise.

c) Replace the Evaporator Fan:
This portion is located on the backside of the refrigerator. If you want to reach for this portion, you have to remove the freezer portion and the inside panel by removing the holding screws.
Use a screwdriver to remove the inside panel and see if the Evaporator fan is spinning correctly or not.
An improper spinning of the fan blades may cause any wear and tear of the wires or other components connected there.
If there any corrosion of the wire or rubber grommet connects with the fan blades to causes the rattling sound, you have to replace the total Evaporator Fan to repair the noise.
d) Let the professional check the Compressor:
Rattling noise due to the compressor problem is a complex issue and should use a professional to diagnose and repair it.
You can primarily identify whether the sound is produced due to Compressor or not.
Disconnect the power supply of your refrigerator; disconnect the power supply of the motor of the condenser fan.
