How To Fix A Noisy Refrigerator Fan?

Topic: How To Fix A Noisy Refrigerator Fan?

Your refrigerator is constantly running to keep perishable foods in the refrigerator or freezer. To do this, the unit has to perform multiple tasks, many of which cause a lot of noise. Refrigerators have several motorized parts that are audible, sometimes from another room. Determining if noise is a problem requires basic troubleshooting. If you hear a very loud sound coming from your refrigerator, there may be a problem that needs repair.

Evaporator fan motor

One motor that can wake up noise in the refrigerator is the evaporator fan motor. This unit is located in the freezer compartment of the unit and is responsible for pushing cold air through the evaporator coils to provide cool air to the rest of the unit. When the fan turns on, there will be a sound audible with normal operation, but a loud sound from the fan motor may indicate a problem. You can tell if the sound is coming from the evaporator blower motor if the noise gets louder when you open the freezer door. The motor is located next to the evaporator coils behind the rear wall of the freezer compartment. If there is no ice blockage causing the fan blades to sound, the noise is probably coming from the motor itself, which means it is malfunctioning. If the motor is damaged, you must replace the fan entirely.

Condenser fan motor

If the noise seems to be coming from the back of the refrigerator, it is probably from the condenser fan. The noise can be lint and dust that builds up and makes the fan run faster. If the noise persists after cleaning the fan, there is likely a problem with the fan motor. It will need to be replaced.

Defrost timer motor

If the motor noise is coming from the bottom of the refrigerator, remove the protección placa to see if you can locate the source. If the noise is coming from this area, it is probably a problem with the defrost timer motor. This motor controls the timer which tells the defrost heater to turn on and off to prevent frost and ice from building up around the evaporator coils. The electric motor can start to deteriorate due to intensive use and become noisy. Replacement is the best solution to this problem.

Compressor motor

The least desirable source of noise in your refrigerator is a compressor problem. These expensive components are necessary for the refrigerator to cool properly. However, their repair or replacement is necessary from time to time. If the noise you hear is a loud clicking or buzzing noise coming from the back of the device, this could be the source. In addition, the mounting springs of a compressor sometimes break and when the engine stops, the compressor starts and makes a loud pounding sound. Either way, the refrigerator needs major repairs to fix the problem.

How To Fix A Noisy Refrigerator Fan – 5 Step to Fix

Refrigerators are often noisy, and many of these sounds are normal. However, when your refrigerator begins to make unusual noises, it can indicate a number of situations. Doing something as simple as leveling the refrigerator or changing parts of it can solve the problem.

Step 1
Determine where the noise is coming from. Noises from different parts of the refrigerator point to specific problems. Determining whether the noise is coming from inside, outside, or from the bottom of the refrigerator helps diagnose the problem.

Step 2
Check that the refrigerator is level. If not, put a small piece of cardboard or wood underneath it on one side to level it. Leveling the refrigerator can automatically eliminate sound problems.

Step 3
Open the freezer to hear if the noise gets louder. If so, it may be caused by the evaporator fan. If the fan is the culprit, replace it to get rid of the noise.

Step 4
Move the refrigerator away from the wall and check the condenser fan in the back. A metal panel can cover the fan and can be removed with a screwdriver. Check to see if this fan is the culprit. If so, you will need to clean and change the fan.

Step 5
Listen to the bottom of the refrigerator to see if the noise is coming from there. If you hear a rattle, the drain pan may be open. Shake the tray securely in place or secure it to the refrigerator with tape to stop it making the noise.

Step 6
Unplug the refrigerator and listen in the back. The fans will immediately stop working. If this part of the refrigerator continues to make noise after the fans are turned off, the sound may surely come from the compressor that is located in the back, near the bottom. If it’s a compressor problem, you’ll need to change it or get another refrigerator.
