What this means on this family
When the MS family gets loud, the useful question is which noise it is making, not how loud it is. The table on this page carries a single model number, so everything here describes one build. Some sounds on these cabinets are normal and one of them is urgent, so this page starts by separating the two.
The observations that separate this fault from its neighbours
- The cabinet rocks when a door is closed — A levelling fault with a noise attached. It also stresses the door seal, so it is worth fixing for two reasons.
- A hum that has grown louder over months — The condenser fan or the compressor working harder than it used to, often because the coil is dirty rather than because either part is failing.
- Gurgling, boiling or a trickle after the unit stops — Refrigerant settling and melt water running to the drain. Normal on every refrigerator, and the most commonly reported non-fault.
- A sharp crack or pop at intervals — Plastic and metal expanding and contracting as the cabinet changes temperature, most obvious during and after a defrost cycle.
- NEAR MISS — a hiss or a smell with the noise — Stop and isolate the cabinet. Anything that sounds like escaping gas or smells burnt is not an ordinary noise complaint.
Ranked causes for these models
- Normal operating sounds — First on the MS family, because more of these complaints end here than anywhere else. Gurgling as refrigerant settles, a trickle as melt water runs to the drain, cracks as the liner expands, and a change in tone as the compressor changes speed are all normal, and on a quieter cabinet they are simply more audible.
- The cabinet as a sounding board — Second, and the test is immediate: press on the cabinet while it makes the noise and see whether it changes.
- Something touching a fan blade — Third. This is the first genuinely mechanical cause on the list, and it is still usually free to fix — ice inside, debris behind.
- Bearings in either fan — Fourth. A bearing is a part, so it sits below every cause that is not. It announces itself with a squeal or a grind that does not change when the obstruction checks come up clean.
- The compressor and its mounting — Last. Hardened mounts make an ordinary compressor sound alarming; a genuinely failing compressor almost always brings a cooling fault with it.
Check in this order, and why
- Locate the noise before doing anything else — Inside the cabinet, behind it, or under it. Three locations, three separate halves of the list.
- Note whether it keeps time with a fan or with the compressor — A rhythm that matches a fan is an obstruction; a steady hum is the compressor or a mount.
- Open the door and listen again — On most cabinets that stops the internal fan, so a noise that disappears has just named itself.
- Lean on each corner of the cabinet in turn — A noise that changes under hand pressure is resonance, and it needs a spirit level rather than a part.
- Pull the cabinet out and look at the back with the power off — Last because it is the most work, and by this point you know whether the noise is even back there.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before reaching behind any panel or near a fan — a capacitor can hold a charge after the power is off, and a condenser fan restarts without warning. The compressor and the tubing around it can be hot enough to burn immediately after running, and the fins at the condenser are sharp. Never defeat a door switch to keep an internal fan spinning while you look at it. If the noise came with any change in how the cabinet cools, treat it as a cooling fault first — a refrigerator holds food safely at 40 °F (4 °C) or below.

When to call a technician
Call once the cabinet has been levelled, cleared and defrosted and the noise is still there. Bring three answers with you: where the noise is, whether it keeps time with a fan or the compressor, and whether the cabinet is still cooling normally. On the MS family those three usually decide the repair before a technician arrives.
