The short answer
On a Fagor refrigerator that is making an unfamiliar noise, the cause to suspect first is compressor mounts and running hum, with evaporator fan blade catching frost or its shroud behind it. The ranking below is written for the static cold-plate build, which you can confirm in seconds: open the door and look at the back wall: bare metal with visible tubing and no grille means there is no evaporator fan at all. Everything in front of the freezer rear panel — levelling, clearing, seating the pan — is owner work; what sits behind that panel is not.
What you observe
- A clatter from the freezer at intervals with no pattern — Ice dropping into the bin, which surprises people most at night.
- Single sharp cracks separated by long silences — Expansion and contraction around the defrost cycle. Normal on a frost-free cabinet.
- A gurgle or hiss that fades as the cooling stops — Refrigerant moving. It becomes a fault only when a tube is touching the cabinet.
- NEAR MISS — the noise comes with a cabinet that is no longer cold — Noise plus warmth is a cooling fault, not a noise fault, and the cooling page is the right one.
Causes, most likely first on this brand
- Compressor mounts and running hum — Ranked first here: the compressor is a sealed motor on rubber mounts, and mounts harden with age. A hum that used to be inaudible becomes a drone that carries through the floor when the mounts stop absorbing it, and the appliance sounds worse in a hard-floored room than the same unit does on carpet.
- Evaporator fan blade catching frost or its shroud — Second: frost forming on the blade tips unbalances the fan long before anything fails, so the noise arrives gradually and the owner cannot say when it started.
- Water inlet valve and pipe hammer at fill — Third: the pattern is one short thump, separated by hours, always following the fill buzz.
- Drain pan or drip tray rattling on its rails — Fourth: it usually appears after the appliance has been moved for cleaning, because the pan is the one component that can be knocked off its seat without anyone noticing.
- Cabinet out of level or a foot not carrying weight — Fifth: the adjustable feet were set when the appliance was installed and almost never since.
Check in this order, and why
- Put a hand flat on the cabinet side while it runs — A drone you can feel as much as hear points at mounts and floor coupling rather than a part.
- Open the freezer door and listen for the change — The fan stops when the door opens, so a noise that vanishes on opening is inside the cabinet.
- Listen for a thump that follows a fill buzz — That sequence puts the noise in the plumbing, not in the appliance.
What an owner can safely check
- Check the tubing at the back for a point of contact with the cabinet — Easing a tube off the panel by hand ends a buzz that no part replacement would have fixed.
About 10 min
- Press each front corner and adjust the feet until nothing rocks — Costs nothing, needs no tools on most cabinets and removes the whole vibration class.
About 10 min
- Seat the drain pan on its rails — A dry pan resonating over a warm compressor is loud out of all proportion to the problem.
About 5 min
- STOP HERE if the noise is behind the freezer rear panel — That panel carries the fan and the defrost heater, and the work behind it is not owner work.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired exactly as it is: it cuts power to the cabinet fan for a reason, and defeating it puts a spinning blade in a space your hand goes into. Anything on the sealed system is licensed work, so if you find oil at the tubing, stop there. Get help before moving the cabinet: it is heavier than it looks and it will pivot on its front feet.
When to call a technician
The line is the panel. Levelling, clearing the compartment, seating the pan and silencing the ice maker are all owner work; anything that requires the freezer rear panel off, or a meter on a fan motor, is not.

Written for Fagor refrigerators as a class, not for one family. No family-specific page for this brand and appliance is published here yet; where one exists for your unit it takes precedence over this page. Wiring colours, torque figures and part numbers are deliberately not here: they differ by family.
