The short answer
Noise from a Beyou BF refrigerator is diagnosed by when it happens, not by how it sounds. On this family a noise that comes and goes with the fan is an evaporator or condenser fan story, one that tracks the defrost cycle is ice contact, and one that is continuous with the compressor is the only expensive answer.
What an owner actually sees
- Rattling or humming from the bottom rear that tracks the compressor — Present whenever the compressor runs and silent between cycles. That points into the machine compartment rather than the cabinet.
- Popping and cracking for a stretch, then quiet for hours — Thermal movement of the liner and coils during and after defrost. Normal on most cabinets, and worth naming so it is not chased.
- A grinding or scraping that rises and falls with the fan — A blade contacting an ice ridge or a shroud that has shifted. It is the loudest of the common faults and the least serious.
- NEAR MISS — the noise arrives with a cabinet that is warming — Noise plus a loss of cooling is not a noise fault; it is a cooling fault that happens to be audible.
What it usually turns out to be, in order
- Evaporator fan blade contacting ice or a displaced shroud — Leads the list because the blade runs close to its housing by design and it takes very little to put them in contact — a ridge of ice, or a shroud knocked out of true during previous work.
- Evaporator or condenser fan motor bearing worn — Second.
- Compressor mounts hardened, or the cabinet not level on the floor — Third, and free.
- Drain pan loose, or tubing touching the cabinet or another tube — Fourth.
Check in this order, and why
- 1. Open the freezer door while the noise is running — The door switch cuts the evaporator fan, so a noise that stops is in front of you and a noise that continues is behind the cabinet.
- 2. Put a clock on it — Does it run with the compressor, arrive in bursts every few hours, or never stop?
- 3. Inspect the machine compartment and load all four feet — Loose pan, tubing against the shell, debris in the condenser fan, cabinet rocking on three feet.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Levelling this cabinet means adjusting the feet, not shimming the unit with whatever is to hand, and moving a refrigerator is a two-person job — a cabinet walked on its feet by one person is how doors go out of square and seals stop sealing.

Owner fix or service call
Call when the noise is constant, low and indifferent to the doors, the fans and the defrost cycle, because that pattern points at the compressor and the compressor is not owner work. Call as well if a fan is clearly the source but the ice keeps coming back after you clear it, since that is a defrost fault presenting as a noise. Levelling the cabinet, reseating a drain pan and separating tubing from the shell are all owner work and resolve a good share of these calls.
