Start here
A new noise from a cabinet is a locating problem before it is a repair problem. Where the noise comes from, and whether it tracks the compressor or the fan, sorts nearly every case within a few minutes and without any tool. This class of appliance draws less than a table lamp, which makes installation faults far more likely than hardware faults. The first two steps cost nothing at all.
Symptoms and near misses
- Gurgling and popping after the cabinet stops — Refrigerant and expanding plastic, and normal in almost every case.
- A buzzing that arrives with the ice maker — The fill valve chattering, which is a water-supply symptom rather than a cooling one.
- A rhythmic scraping or ticking from inside the freezer — Almost always a fan blade striking frost or a misplaced item.
- NEAR MISS: a noise that comes with warm air and long run times — Then the noise is secondary and the cooling fault is the page you want.
What is usually behind it, in order
- Condenser fan obstructed or worn — Most likely here. It leads on a compact cabinet because one small fan does all the work and sits close to the cabinet wall, so anything that touches it is audible across the room. A fan at the back of the cabinet picking up dust, cardboard or a bearing that has dried out. Usually louder when the compressor runs.
- Cabinet not level or resting on an uneven floor — Next most likely. A cabinet standing on three of its four feet will buzz at particular compressor speeds and nowhere else.
- Loose panel, drip tray or shelf — Third in the order. Resonance rather than a fault.
- Compressor mounting grommets hardened — Then this one. Rubber that has gone stiff with age transmits normal running vibration into the cabinet and the floor.
- Body: Ranked for a Brisas refrigerator specifically. The order is the value here; the list on its own would be the same list anyone could write.
Check in this order, and why
- Open the freezer door while the noise is happening — If it stops or changes immediately, the fan behind that panel is your source.
- Press a hand on the top and side panels in turn — A rattle that stops under a flat hand is a panel, not a part.
- Listen at the back of the cabinet with the compressor running — This separates condenser-side noise from anything in the food compartments.
- Body: The order below is written for a small cabinet, where the structure resonates and the fan is the only moving part of any size.
Step by step, safely
- Take everything off the top of the cabinet and empty the door shelves — Bottles and containers resonate and account for a surprising number of these complaints.
- Level the cabinet on its feet until it does not rock — Work with the doors closed and check again afterwards.
Tools: adjustable spanner
- Defrost the cabinet fully if the noise comes from the freezer and tracks the fan — A blade clear of ice is silent again, and the fault moves to the defrost system.
- STOP before removing a rear panel or a fan shroud — That is a powered assembly behind a cover and it is where owner work ends.
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. Never reach into a fan shroud to feel for an obstruction while the cabinet has power, and never hold a door switch closed to run a fan with the door open.
Where owner work ends
Call if the noise is tied to the compressor rather than to a fan or a panel, if it arrived alongside a loss of cooling, or if defrosting the cabinet silences it and the noise comes back within weeks. A noise on its own is rarely urgent; a noise with warm air behind it is. Ask which of the causes above were ruled out, and how.

What is out of scope
This page is written for the appliance class rather than for one Brisas family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and should be preferred over this one; the brand and appliance hub linked below routes to everything more specific that exists today.
