The short answer
On a Marshall Fridge refrigerator, a new noise is most often a condenser fan catching on debris or wearing out rather than vibration passed into a cupboard, worktop or neighbouring unit. The airflow path and the installation come first, because a cabinet chosen for where it looks right is nearly always standing somewhere that restricts it. All three checks below are owner work, and not one of them needs a part.
What you are seeing
- A regular tick or scrape in time with a fan — Rhythm is the tell: anything mechanical repeats at the speed of whatever is turning.
- Noise that is worse with the doors just closed — Air movement inside the cabinet is loudest right after the door shuts, which points inside rather than behind.
- A buzz or rattle that stops the moment the compressor stops — The sound is tied to the compressor running, which points at something vibrating rather than something failing.
- NEAR MISS — the noise comes with the cabinet going warm — Noise plus warmth is a cooling fault, and the cooling page ranks it properly.
Causes, most likely first on this brand
- A condenser fan catching on debris or wearing out — The fan at the base or the back draws air over the condenser. Dust, a fallen crumb tray or a stray bag will catch the blade and give a regular ticking or scraping in time with the fan. It leads because this cabinet's fan sits where debris collects, and a blade that catches is the commonest mechanical noise on it. It is a display piece as much as an appliance, so it is usually placed where it looks right rather than where it breathes.
- A rattle from a loose panel, grille or tray — A drip tray sitting in its cradle, a base grille clipped on loosely or a rear panel that has worked free will buzz against the cabinet whenever the compressor runs, and go quiet the moment it stops. It sits here because it costs nothing to rule out and it explains a noise that comes and goes with the compressor.
- Vibration passed into a cupboard, worktop or neighbouring unit — A cabinet touching a wall, a cupboard side or another appliance uses that surface as a soundboard. The machine is no louder than it was; the room has simply been given a way to broadcast it. It is last because a cabinet with air around it has little to transmit into.
Check in this order, and why
- Unplug it, pull the base grille and look at the fan blade — Debris on the blade or in its path is visible immediately. First, because it is the likeliest to end the job.
- Press a hand on each panel, the grille and the drip tray while it runs — If the noise stops under your hand, you have found it without a single tool. Second, once that is clean.
- Slide the cabinet a finger's width clear of anything it touches — If the noise drops away, the contact was the amplifier. Third, and by now the answer is usually in hand.
The steps, with tools and times
- Unplug the cabinet, clear the fan and the coil, refit the grille — Vacuum and a soft brush; check for a bag or a crumb tray that has fallen behind.
Tools: vacuum, soft brushAbout 25 min
- Reseat the drip tray, the base grille and any loose trim — Push each one home until it clips. Nothing here needs a tool.
About 10 min
- Move the cabinet clear of walls, cupboards and other appliances — A finger's width of air is enough to stop a surface acting as a soundboard.
About 15 min
- STOP — note when the noise happens and what it sounds like — A described noise with a pattern behind it is worth more to a technician than a guess at a part.
The part that is not optional
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never put a hand near a fan to find a noise while the machine is live — it can restart on its own at any moment.
When to call a technician
Call when the noise is a changed compressor hum, when it comes with the cabinet losing temperature, or when a fan is audibly failing behind a panel that has to be defrosted to reach. Rattles, levelling and debris are owner work and account for most of these calls. On this brand the styling parts and the refrigeration parts come from different places, and only one of them is easy to get.
