The short answer
A refrigerator is never silent, and on this platform the sounds that matter are the ones that change rather than the ones that are loud. Where the noise sits — top rear, bottom rear, inside the freezer — narrows it faster than any description of the sound ever will. Only the last item on the list needs a technician, and it is the one that is least often the answer. Part numbers are left to the table above; the text stays with the method, which is what holds.
The sounds and what they mean
- A buzz that appears only for a minute or two at a time — Something operating on a cycle — a defrost heater energising, a damper motor running, or a valve opening for the icemaker.
- A sharp click a few seconds before the hum starts or stops — The start relay operating. A single click is expected; repeated clicking without the compressor running is not.
- A knocking or thumping from the compressor area — Mounts that have hardened with age, or a cabinet that is not sitting level on its feet.
- A popping or cracking from the walls of the cabinet — Plastic expanding and contracting through a defrost cycle. Loud, alarming and entirely normal.
- 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.
The ranking for this platform
- Evaporator fan blade striking frost or ice — Top of the list on this platform for a structural reason: this is the only moving part living in the compartment that ices up, so it meets the ice first and reports it as sound.
- Evaporator fan bearing worn — The same fan, further along. A bearing that has been running in a cold, damp compartment for years develops a steady chirp that does not come and go with the ice.
- Condenser fan obstructed or out of balance — Down at the bottom rear, where the cabinet breathes off the floor. Whatever is on the floor ends up in the shroud, and an out-of-balance blade beats against it.
- 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.
- 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.
- Have someone open the freezer door while you listen at the back — Separates the two fans from each other, since only one of them stops when the door opens.
- Empty the drain pan and refit it squarely — Costs nothing, and a pan walking in its tray is among the loudest and least serious faults here.
What to do before the panel comes off
Safety
Take the power away first — at the plug, or at the breaker where there is no reachable plug — and treat any capacitor as charged until proven otherwise. The cabinet is heavy and top-heavy once a door swings open, so get help before pulling it out to reach the condenser fan.

The line between a fix and a call
Stop at the point where the noise turns out to be a bearing. A worn fan bearing is a straightforward part, but reaching it on this platform means taking out the freezer rear panel with the cabinet full, and that is where owner repairs on this family tend to end badly.
