DIY: Troubleshooting a Loud Refrigerator

Standard

Do you hear that? Your refrigerator is running.  If your unit is making a ton of noise it probably means that it is overworking – which can not only be a pain to listen to but also affect the lining in your wallet. In this DIY article were going to be exploring some problem areas you can focus on if your refrigerator is being abnormally loud.

Warning: Before doing any work on your appliances, make sure that you cut the power to it before beginning to avoid any accidents or harm to yourself. 

1.) Dust/Debris

There are plenty of reasons that dust could be lingering around the house; perhaps you have been busy and haven’t gotten around to cleaning, or you just have a multitude of animals living with you. Whatever the case may be dust can accumulate and lower the efficiency of your fridge which can cause the fridge to overwork.

Solution: Again, make sure you read the warning at the top of the page before doing any of these repairs. The condenser coils are typically accessed through the front or back bottom panel on your refrigerator unit. If you have a lot of buildup, you can use a vacuum cleaner in order to remove the dust. If you still have remaining debris on the unit you can use a small brush in order to gently brush off any remaining particles.


2.) The Temperature Dial

It’s happened to plenty of us, you reach into the fridge to grab something on the top shelf and you accidentally bump the temperature control switch on the fridge. Usually we don’t notice this until one of two things happen: we recognize the fridge being abnormally loud for a prolong period of time or we find our food spoiled from being too hot.

Solution: The normal temperature range for a refrigerator that has been deemed safe by the Federal Food and Drug administration is within the range of 37-40 degrees, and since refrigerators use a vast amount of energy even setting the temperature accidentally lower by 10 degrees can make a 25% increase in energy consumption.


3.) Drain Pan

If you hear a muffled rattling sound coming from underneath your refrigerator unit, the culprit is probably a dislodged drain pan.

Solution: This isn’t a terribly complicated fix, refer to your owners manual on the best way to access your drain pan. Typically you will have to use a bottom access panel on the front or back of your unit to physically access the drain pan. Most people find that using a piece or two of duct tape works well so that it doesn’t move in the future.


4.) Fan Blade

If the refrigerator is noisy, especially when the door is opened, the evaporator or condenser fan blade might be the culprit.

Solution: Check the fan blade by hand if it doesn’t turn freely, check to see if the blade has anything that could blocking its path. If that’s not the case, check the condenser fan if it also has any obstructions that could be blocking its rotation.


5.) Evaporator Fan Motor

If you are hearing a loud consistent noise coming from the freezer area, the problem may be because of this part. There are some other calling cards that could lead you to believe the fan motor is gong on your unit which could include your freezer not freezing things as fast as usual and also your refrigerator being less cool than normal even though you haven’t adjusted the temperature settings.

Solution: The reason why this is creating a loud sound is because the compressor is kicking on to try and send power to the fan motor to cool your refrigerator  but it’s sending power to a faulty/damaged motor. This results in your compressor staying on because your motor is not functioning. Refer to your manual to proceed with trying to replace this part. The fan motor is typically in the very back of the freezer, so you will most likely have to remove all your food in order to locate this part. There will be a back panel to remove first that houses the fan motor.
