The answer first
A new noise on the BUFR line is worth locating before it is worth diagnosing: on these models the two fans are at opposite ends of the cabinet and each is reachable without disturbing the other. That layout is why the check order below starts with a door test rather than with a panel.
What you are seeing
- A hum that never stops at all — A compressor that no longer cycles off runs continuously, and the constant hum is the first thing owners notice about it.
- A rattle that changes when the cabinet is pushed — If a hand on the panel changes the sound, the sound is a panel. Check the rear cover and the pan first. Owners of the models listed in the table on this page describe this in almost identical words.
- A ticking or scraping that stops when the freezer door opens — The door switch cuts the evaporator fan, so a noise that dies with the door open is that fan and nothing else.
- A short squeal at the start of each cycle — Start-up squeals that fade are a bearing on the way out rather than one that has failed.
- A gurgle or trickle from inside the cabinet — Refrigerant moving through the evaporator. It is normal, it is louder on some cabinets than others, and it needs nothing done.
- NEAR MISS — the noise is from the ice bin, not the machine — Cubes dropping and the auger turning are loud and entirely normal, especially on a bin that is nearly empty.
- NEAR MISS — the noise came with a warming cabinet — Then the noise is secondary and the cooling failure is the page you want. Diagnose the temperature first.
Causes in likelihood order
- A failing evaporator fan motor — Top of the list here. Distinct from ice contact: the sound is present from the moment the fan starts rather than building over weeks, and it does not improve after a defrost. What separates the BUFR line here is the order, not the parts.
- Blocked air returns forcing the fan to work harder — Next most likely. Food packed against the rear wall raises the whistle and makes the fan audible in a cabinet that used to be silent. It also frosts the coil, which brings cause one along in a month or two.
- A genuinely failing compressor — Then this one. Last, and it is rare. It sounds like a hard metallic knock on start, the cabinet warms afterwards, and it is not an owner repair under any circumstances. It is one of the few places the models listed in the table on this page genuinely diverge.
- Ice contacting the evaporator fan blade — Fourth, and getting rarer. Ranked first on this platform. Frost builds where the airflow stalls, reaches the blade tip, and each rotation produces the tick owners describe as a clock. It is a defrost symptom presenting as a noise.
- Compressor mounting grommets perished with age — Fifth, and uncommon. The rubber mounts harden and lose their isolation, so a compressor that is mechanically fine transmits its whole cycle into the cabinet shell.
The diagnostic order
- Put a hand flat on each panel in turn — A sound that changes under your palm is a panel resonating, not a component failing.
- Listen from the next room with the kitchen quiet — Distance changes what you can hear and it separates the two classes of noise. The BUFR line puts this within reach without a teardown.
- Note whether the noise is present at start-up only — Start-up squeals point at a drying bearing; continuous noise points at something else.
- Switch the ice maker off for a day — A one-day test that eliminates the entire water side of the machine.
Isolate it first
Safety
Power off before a panel comes off: unplug the appliance or switch off its breaker, and treat the compressor compartment as live until you have confirmed it is not. Warm water and cloths are the only safe way to clear ice. Refrigerant work is licensed work and needs recovery equipment, so nothing on the sealed side belongs in an owner’s afternoon.

When this becomes a service call
Call when the noise survives a full manual defrost and a levelling check, because what is left is a motor or a bearing behind a panel. Call sooner if the sound is a hard knock and the cabinet is warming, which is the one noise pattern on this page that points at the sealed system.
