Make sure the fridge is standing straight and not shaking. If it is uneven, it may create vibration noise while running.
If the fridge is touching the wall, it can create rattling or vibrating sounds. Leave a little space behind it.
Sometimes bottles, trays, or utensils inside the fridge touch each other and create noise while the fridge is running.
A soft humming sound is normal. Loud rattling, clicking, or continuous buzzing usually means something is loose or blocked.
If the sound is unusually loud or continues even after checking everything, technician support may be required.
Keep the fridge straight, avoid overloading, and leave some space behind it to reduce noise.
