A fridge that isn’t level can lead to problems like odd sounds and poor cooling.

To level your refrigerator, start by checking if the front is higher than the back. Use a level tool, placing it on a shelf to determine the tilt.

If necessary, adjust the leveling legs-most fridges have two in the front. Turn the legs clockwise to raise or counterclockwise to lower.

After leveling, check if the fridge runs smoothly and without noise. Mr. Appliance suggests checking your changes by slowly moving the fridge forward and allowing it to settle back to make sure it is stable.

This simple approach can reduce noise significantly while improving energy efficiency.

3. Inspect the Condenser Coils

Did you know that dirty condenser coils can lead to decreased efficiency and loud operational sounds?

Regular inspections of your condenser coils can make a significant difference. A clean coil operates at about 90% efficiency, while a dirty one can drop to 70%, leading to an estimated 20% increase in energy costs.

Noise levels can rise by 10-15 dB when coils are clogged. To prevent this problem, clean every six months using tools like a soft brush or a shop vacuum. The U.S. Department of Energy notes that maintaining your air conditioning unit, such as keeping the condenser coils clean, is crucial for energy efficiency and operational silence, as detailed in their Air Conditioner Maintenance guide.

Following these steps helps your unit work longer, lowers noise, and makes cooling better, so your space feels more comfortable.
