Refrigerator is noisy or loud: Common Causes & How to Fix

Repair Instructions:

Excessive noise or loudness when opening refrigerator doors could indicate an issue with the evaporator or condenser fan blades. First inspect the evaporator fan behind the freezer back panel. Try rotating it by hand. If it doesn't spin freely, look to see if it's rubbing against or obstructed by something. Also check the condenser fan on the bottom back of the refrigerator for any blockages. Something caught on the fan blades or causing them to rub could lead to loud noises from friction or resistance to spinning. Clearing any obstructions and ensuring the blades move freely without rubbing will help quiet abnormal noises, especially when doors are opened.

Repair Instructions:

This small component continuously measures the ambient temperature inside the appliance and sends this data to the control board. Based on this information, the control board makes decisions, such as when to turn the compressor on or off, to maintain the set temperature levels. When a refrigerator is noisy or loud, the temperature sensor itself doesn't typically produce such sounds. However, if the sensor is malfunctioning and sending incorrect temperature readings to the control board, it can indirectly contribute to noise issues. For instance, if the sensor falsely indicates a higher temperature, the control board might cause the compressor or fans to run more frequently or for extended periods, leading to increased operational noise.

How to Replace Refrigerator Temperature Sensor

   • Use a screwdriver to carefully detach the sensor cover, exposing the temperature sensor and other related components.
   • Keep track of the screws and store them in a secure place to prevent misplacement.

4. Detach the Old Temperature Sensor:

   • Identify the wires connected to the temperature sensor and take note of their positions.
   • Gently detach the wires by either sliding off the connectors or using pliers, depending on the type of connection.
   • Remove the old temperature sensor from its housing by carefully pulling it out.

5. Install the New Temperature Sensor:

   • Insert the new temperature sensor into the designated slot, ensuring a secure fit.
   • Reconnect the wires to the corresponding terminals by firmly pressing them into place.

6. Replace the Sensor Cover:

   • Reattach the sensor cover by aligning it with the designated slots and securely tightening the screws.
   • Confirm that the cover is properly secured and adequately sealed.

Repair Instructions:

If the control board malfunctions or sends erratic signals, it might cause components like fans, compressors, or motors to operate irregularly. For instance, a fan might be instructed to run at a higher speed than necessary, leading to unusual noises. Or, the compressor might cycle on and off more frequently than it should, causing louder operational sounds. Electrical issues or miscommunications stemming from a faulty control board can result in components working out of sync or in an unintended manner, leading to noticeable and unusual sounds.

How to Replace a Refrigerator Control Board

1. Unplug the Refrigerator. Unplug the refrigerator from the electrical outlet to ensure your safety while working on the appliance.
2. Locate the Control Board. Identify the current control board, typically located in the refrigerator's control panel, which is often located on the front of the appliance, near the top or inside the refrigerator section.
3. Document Wiring Connections. Take photographs or make a detailed note of the wiring connections on the old control board for correctly reconnecting the wires to the new control board.
4. Disconnect Wiring. Gently disconnect the wires and connectors from the old control board.
5. Remove the Old Control Board. You may need to remove screws, clips, or retaining brackets securing the old control board. Carefully remove these components to access the control board.
6. Install the New Control Board. Position the new control board in the same location as the old one and secure it with screws, clips, or brackets.
7. Reconnect Wiring. Reattach the wires and connectors to the corresponding terminals on the new control board.
8. Plug in the Refrigerator. Allow the refrigerator to run for a while. Test the control board's functionality by adjusting temperature settings, ensuring that it properly regulates the refrigerator's temperature and features like defrost cycles.

Repair Instructions:

An unleveled refrigerator can cause vibrations and rattling noises. Check that the unit is properly leveled and firmly positioned on the floor. Most refrigerators have adjustable front legs or rollers that can be turned to level it. If needed, use a level to verify the refrigerator is evenly balanced side-to-side and front-to-back. If unlevel, turn the adjustable legs or rollers to raise or lower each corner until the unit sits evenly. Leveling provides stability, preventing vibrations that lead to noises.

Repair Instructions:

The home may have insufficient water pressure. The water inlet valve supplies water to the water dispenser. The water inlet valve requires a minimum of 20 psi to function properly. Check the water flow and test the pressure to determine if it is at least 20 psi. Inadequate household water pressure could result in sputtering or loud noises.
