While most refrigerator noise fades into the background, an unfamiliar sound commands attention. Why is my Bosch refrigerator making noise? A fridge that isn’t level can result in loud vibrations. Learn how to quiet a Bosch refrigerator making noise with these troubleshooting tips.
5 Reasons for a Bosch Refrigerator Making Noise
Are Bosch refrigerators quiet? Most operating sounds are normally hard to hear, making louder volumes a clue that something may be wrong. Here’s how to pinpoint the reason for a Bosch refrigerator making noise and implement the right solution.
Bosch Refrigerator Is Not Level
An unlevel refrigerator is one of the most common reasons for a Bosch refrigerator making noise. Though slight vibration is part of normal operation, the refrigerator may make louder vibrating sounds if it’s not resting evenly on the floor. Use a carpenter’s level to determine if the refrigerator is level. If it isn’t, it’s leveling feet can be adjusted up or down with a wrench until it sits evenly.
Evaporator Fan Obstruction
A refrigerator’s evaporator fan helps cool refrigerant, producing cool air for the refrigerator. On most Bosch refrigerators, the evaporator fan is located behind a rear freezer panel. Given this location, ice can occasionally build up on the fan blades, obstructing their rotation. When this happens, the refrigerator won’t cool sufficiently. As soon as the temperature starts to climb, you’ll notice your Bosch refrigerator is beeping to alert you to the temperature change.
Remove the freezer’s rear panel to inspect the fan blades. If they’re iced over, the refrigerator may need to be manually defrosted to melt the blockage and restore the fan’s function. If the fan isn’t obstructed but the blades are damaged, it must be replaced.
A fridge making grinding noise may have an evaporator or condenser fan motor failure. Both of these fans work to cool refrigerant at different points in the refrigerator. If either of their motors start to fail, they’ll make a loud grinding sound as they operate. As with a fan obstruction, you may also notice the temperature inside the refrigerator start to rise since the refrigerant won’t cool properly.
How can you tell if the condenser or evaporator fan is responsible for your Bosch refrigerator making noise? Since the evaporator fan is located in the freezer, loud noises will seem like they’re coming from inside the refrigerator. By contrast, condenser fan malfunctions sound like they’re in the back of the unit. In either case, a professional service should assess the motor and replace it, if necessary.
Defective Water Inlet Valve
The water inlet valve rests on the refrigerator’s water line, opening and closing to provide the fridge with water from your home supply. If the valve is defective, it can make a loud buzzing sound as it operates. Water and ice production may also be reduced or ice cubes may be smaller or misshapen.
A defective water inlet valve should be assessed by a professional service. While mineral deposits or electronic failure can cause it to malfunction, it can’t be repaired and should be replaced.
Why is my Bosh refrigerator beeping if the fans and their motors are functioning? Though rare, loud Bosh refrigerator noise may ultimately be due to a compressor problem. The compressor is the heart and soul of the refrigerator, circulating and condensing refrigerant to produce cool air. If it starts to break down, a lack of cool air will cause the refrigerator’s internal temperature to rise. You may also hear the compressor making loud buzzing sounds or clicking on and off repeatedly.
A professional refrigerator repair service should inspect the compressor and replace it, if needed.
