Generally, running refrigerators do produce noise, and a lot of these sounds are fairly normal. However, when your refrigerator begins to produce a loud noise that is not normal, this may be a telltale sign of a range of problems. For the average homeowner, the question that begs is how do you troubleshoot the source of noise in a noisy fridge? The following article provides a troubleshooting guide for fixing a noisy refrigerator.

Instructions

First, establish where the noise is originating from. Noises originating from various parts of the refrigerator signify particular problems. Generally, refrigerator noises may originate from the interior, outside or underneath the fridge. Observing the real source of the noise will help you to identify the problem.
Inspect whether your refrigerator is level or not. If it isn't, position a small block of cardboard or wood beneath any loose footing to achieve stability. Levelling a refrigerator can definitely get rid of disturbing sounds.
How do you diagnose noise originating from inside the fridge? Open the freezer to check whether or not the level of noise increases. If you notice the noise increases with the opening of the freezer, then the source of the noise is most likely the evaporator fan which is inside the fridge. Normally, a faulty evaporator fan produces rattling sounds. Replace it to get rid of the disquieting sounds.
To diagnose noise coming from the back of the fridge, you need to inspect the condenser fan, often located at the rear of the fridge. Remove the metal panel cover and listen closely to establish whether or not the condenser fan is the source of the loud sounds. You may either clean or replace it to eliminate the problem. Additionally, turn off the power to the fridge and listen to the rear side of the unit. Once the power is off, fans will stop running straight away. However, if you notice that the fridge continues to produce noise even after the power and fans have switched off, then the source of the noise may be originating from the compressor, which is situated at the bottom half of the unit's rear side. A faulty compressor calls for immediate replacement.
Listen to the base of the fridge to detect if the noise is originating from beneath. If you detect a deafening sound, the source of the problem might be the fridge's drain pan being ajar. Simply, use a tape to secure the pan in its recommended place to eliminate the rattling sounds.
