Some solutions to the problem of large noise in the freezer

1. Adjust the balance of the four feet at the bottom of the freezer. The freezer should be placed on a flat and hard floor. Place the bottom four feet on a flat surface to balance them. Many refrigerators have a 4-foot adjustment knob at the bottom, which can be adjusted by fixing the maximum time of noise. If there is no adjustable knob device, you can place a cushion under the freezer foot to balance and minimize the noise.
2. The pipes and cabinets are firmly reinforced. Check whether the reinforced part of the connection between the outer pipeline and the cabinet is loose to avoid resonance when the compressor is working. Therefore, a spring washer must be added to ensure that the outer pipeline is firm and the bolts are not loose.
3. The compressor base must be firmly fixed. Press the compressor tightly with your hand, the noise is greatly reduced, and the noise of raising your hand is increased. Generally speaking, the vibration damping pad used to fix the compressor base is uneven or the bolts are loose, and the compressor base is not strong. It is necessary to adjust and tighten the connecting bolts and replace the gaskets that have lost their elasticity.

4. Accessories must be firmly installed. Freezers and freezer compartments must be firmly installed in fixed locations and sinks, so that users can directly use refrigerators, layered networks, drawers and other accessories. Do not place debris on top of the freezer to prevent noise caused by resonance.
5. Determine whether the compressor is faulty. Pressing the top of the compressor by hand will not reduce noise. Generally speaking, if the gap between the piston and the cylinder inside the compressor is too large to generate noise, the compressor must be replaced. When the freezer does not open the door, about 3 meters away, you can clearly hear the heat of the pot and the sound of the "pick" interval.
6. Use rubber blocks to suppress the vibration of the pipe. The refrigerator is very noisy when used, so the outer contour of the bicycle is cut into a circle with a diameter of 30mm, a circular hole with a diameter of 5mm is cut from the middle, and then cut from the outside to the center, and the eraser is pasted into the tube. When the compressor is started, a few pieces of such rubber blocks can be clamped on the pipe that touches the pipe by hand. A refrigerator needs 10-20 pieces, and the noise will soon be reduced. Because the rubber block can suppress the "resonance" caused by the vibration of the pipe.
7. Spread the four feet of the freezer properly. Place it on a 3-6 cm high liner, adjust the square balance, and increase the air convection space at the bottom of the box. In this way, the noise of the compressor and other noise below can come out from the bottom of the cabinet, reducing the noise generated on both sides and the upper part of the refrigerator.
8. The back and the wall are inclined at a certain angle. Tilt the back of the freezer and the wall at a certain angle, and tilt the back and the wall by l-3 degrees. The freezer has a large opening on one side and a small opening on the side, forming a horn shape. The noise from the large side is so loud that it must face the object. Small areas should be quiet and face human activities.
9. Insert sound-absorbing cardboard along the wall nails. Paste sound-absorbing materials such as fiberglass wool to the cardboard, and then paste the cardboard to the wall behind the freezer (compressor side). The cardboard is 10 cm to 20 cm larger than the back of the freezer.
