Troubleshooting Difficult Appliances

Few things are more frustrating than appliances that simply won't stop having trouble. In addition to disrupting your daily routine, appliances with problems can also absorb a great deal of your time. A few months ago, I spent an entire Saturday trying to figure out why our dishwasher wasn't working. To end these kinds of problems, I decided that it would be smart to invest in an appliance services plan. Simply put, professional technicians would come out and repair our appliances whenever they stopped working properly. This plan was a lifesaver for our family, and this blog is all about why.

Why Your Refrigerator Makes A Loud Buzzing Noise

Your refrigerator should make some noise. However, it shouldn't make a loud, consistent buzzing noise. A buzzing noise is a sign of something going wrong. While some causes are simple to fix, others will need professional attention. If your refrigerator makes a loud buzzing noise, keep reading to learn more about the causes.

Compressor Problems

The compressor is the engine of your refrigerator. It circulates the refrigerant through the system. Like any engine, it has several moving parts. When one of these parts wears or breaks, you get poor performance. In normal conditions, it makes a soft hum. Sometimes, it will become louder during hot weather when it works harder. However, a very loud buzz may indicate it is failing or not working at all.

Condenser Problems

Condensers are the coils located in the back of the refrigerator. They help remove heat from the refrigerant and turn it back into a liquid. These coils often get covered with dust, which reduces their effectiveness. With enough dust accumulation, your refrigerator needs to work harder. Condenser coils sometimes need a good, professional cleaning.

Ice Maker Problems

If you have an ice maker, you may have a water line problem. Ice maker water lines can often become loose or plugged with debris. You may hear a buzzing noise when the ice maker tries to fill. Damaged components, like the inlet valve, can also cause filling problems. Check for a loose or dirty inlet line. If those look OK, then your ice maker may need professional attention.

Positioning Problems

Sometimes, nothing is wrong with the refrigerator, but it is not positioned right. If your refrigerator is not level, you may get a loud vibration. You may get a buzz or vibration if your refrigerator is against a counter or piece of furniture. Sometimes, moving the refrigerator only a few millimeters is enough to reduce the sound.

Miscellaneous Problems

Check your refrigerator for loose pans and trays. These items may vibrate when the refrigerator compressor runs. Refrigerator magnets may also cause a buzzing sound. Check to ensure your door closes properly as well. Don't crank up the settings inside your refrigerator. A too-cold refrigerator setting may cause ice to form and increase your compressor's workload. See if turning down the setting improves the noise.

Buzzing noises are usually a sign of something not working in your refrigerator. Usually, the causes are not dangerous. However, you will want your refrigerator to work as it should. Contact a professional for more information about refrigerator repair
