What the noise usually is
Most of the noises a cabinet in this family makes are normal and the job is to separate those from the two or three that are not. Where the noise sits — top rear, bottom rear, inside the freezer — narrows it faster than any description of the sound ever will. The checks below need no tools at all. The repairs sometimes do. This family resolves to one listing, which makes the page unusually definite about what it covers.
What you are hearing
- The noise stops the moment the door opens — That is the door switch cutting the evaporator fan, and it confirms the noise is that fan rather than anything else.
- A whistling or whining that changes when the door opens — Air moving through a restricted path. The door switch cutting the fan is what makes it change, which identifies the source.
- A rattle or buzz from the bottom rear of the cabinet — Either the condenser fan hitting something it picked up or the drain pan vibrating in its tray. Both are cheap.
- A loud hum that rises and falls with the cooling cycle — Normal in itself. Worth attention only if it is new, or if the pitch has changed since it was installed.
- NEAR MISS — the noise came with a loss of cooling — Then the noise is secondary and the cooling failure is the page you want for this family.
Ranked causes for these models
- Evaporator fan blade striking frost or ice — First on this roster. The fan sits in the one part of the cabinet that accumulates ice, so any defrost weakness reaches it first and it reports the problem as noise long before the compartment warms up.
- Drain pan or loose panel vibrating — The cheapest thing on the list and among the commonest. The pan walks out of its tray and buzzes, and the buzz changes the moment a hand touches the cabinet.
- Compressor mounts hardened, or the cabinet not level — A thump rather than a rattle. A surprising share of these end at a spirit level and a pair of adjustable feet.
- Start relay or compressor fault — Bottom of the list, and it rarely travels alone. A compressor that clicks and will not catch is a different complaint from one that is merely loud.
The diagnostic order for this family
- Open the freezer door while the noise is happening — The door switch cuts the evaporator fan. If the noise stops instantly, you have found it without touching a tool.
- Listen at the bottom rear with the unit running — Separates the condenser fan and the drain pan from anything happening inside the cabinet.
- Press a hand flat against each outer panel in turn — A buzz that changes or stops under hand pressure is a panel or a pan, not a bearing.
- Check the cabinet is level and sitting on all its feet — A cabinet rocking on three points amplifies every vibration the compressor makes. Costs nothing to rule out.
- Note whether the noise tracks the cooling cycle — A noise present only while the compressor runs is a different list from one present all the time.
Safety before diagnosis
Safety
Nothing below happens with the machine live. Unplug it or switch off its breaker, and treat any capacitor as charged until it has been discharged properly.

When to call a technician
Call when the noise is a knock from the compressor area that levelling does not change, or when clicking comes with a loss of cooling. Both of those are the sealed system reporting itself, and neither is owner work on this roster.
