The finding, first
New noise from one of these cabinets is usually a fan or a fan's surroundings, not the compressor people assume it is. Fan blades striking frost, a condenser fan picking up debris and a compressor on tired mounts cover most of what gets reported. Nearly all of it is owner-diagnosable by listening carefully in the right order, which is what this page is for.
What you are hearing
- 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.
- 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 popping or cracking from the walls of the cabinet — Plastic expanding and contracting through a defrost cycle. Loud, alarming and entirely normal.
- The noise started after the cabinet was moved — Almost always the pan, the levelling or something now resting against a wall. A move rarely damages anything mechanical.
- 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.
- 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 later in its life. Years in a cold, damp compartment wear a bearing into a steady chirp that no longer comes and goes with the cooling cycle.
- Drain pan or loose panel vibrating — The cheapest entry on the list and one of the commonest. The pan sits in a tray and walks out of position; the noise is a buzz that changes when you touch the cabinet.
- 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.
Where to listen, first to last
- 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.
- 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.
- 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.
Isolate first
Safety
Before any panel comes off, take the power away at the plug or at the breaker. A capacitor can hold a charge after the power is off, which is why the order is isolate first and open second.

The line between a fix and a call
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.
