# How to Fix an Old Buzzing Refrigerator
If you have had the same refrigerator for a while, certain problems are likely to arise, such as a frequent buzzing sound emitting from the lower portion of the unit. This is caused by dust buildup on the condenser coils. The condenser coils help draw heat out of the refrigerator and allow it to stay cool. You can fix the buzzing problem by cleaning the coils.
