The answer first
On the REF family, a cabinet that has started making a noise it did not make before usually comes down to cabinet not sitting level or not carrying weight evenly. Start with one thing: rock the cabinet gently at each front corner.
What the owner actually sees
- A new noise that arrived after the unit was moved — Moving a cabinet changes what is touching what, which is why so many noise complaints start the week after a kitchen is rearranged.
- A buzz or drone that comes and goes with the compressor — It starts when the cooling starts and stops when it stops, which places it at the compressor deck rather than inside the cabinet.
- A rattle that changes if you press a hand on the cabinet side — Anything that changes when you load the panel is a resonance, not a failing part, and it is usually fixable in minutes.
- NEAR MISS: a click every few minutes and no running at all — A cabinet that clicks and does not start is a relay or control fault, and it belongs on the page for a unit that will not run.
The ranking, and why it is this one
- Cabinet not sitting level or not carrying weight evenly — The lighter the cabinet, the more a small imbalance shows, and the cabinets in this class are light enough that a soft floor or a rug under one corner is enough on its own.
- Tubing, drain pan or panel touching something it should not — It is second rather than first because it takes a look behind the cabinet to confirm, but it is the cause that most reliably explains a rattle that changes when you touch the panel.
- Evaporator fan blade catching ice — A fan that is clipping frost on each revolution makes a rhythmic chopping that is unmistakable once you know it, and it is a warning that the defrost system is already falling behind.
- Compressor mounts hardened or the compressor itself noisy — It ranks below the contact causes because the fix is the same in spirit but the access is not: getting to the mounts is service work rather than an owner check.
- Body: This page covers the REF family, and the table below lists a single model, so nothing here has to be hedged across variants: the ranking is the ranking for that build. That order is the brand-generic order for this symptom, because nothing in how this line is built moves any of these causes past another.
What to check first, second, third
- Rock the cabinet gently at each front corner — Any movement at all means a foot is not carrying, and that is where the noise is coming from.
- With the unit running, press lightly on each rear panel and the drain pan — A noise that changes or stops under a hand is a contact point, and it is almost always fixable without parts.
- Open the freezer and listen with the door switch held in — A chopping that starts with the fan and stops when you release the switch places the noise at the blade.
- Body: The order follows the ranking above rather than the layout of the cabinet: each check either confirms the cause above it or removes it, and they are arranged so that the free checks come before anything that needs the unit moved or a panel off. With one configuration in the field, there is no variant that reorders these.
Safety first
Safety
Cut the power at the plug or the breaker before anything comes off, and keep it off while your hands are anywhere near a blade or a terminal. The compressor deck carries mains voltage at the relay and enough stored charge in the capacitor to matter after the cord is out.

Where the owner checks end
The owner side of this page is everything you can reach without a panel: levels, contents, the drain pan, the rear grille and a defrost. Past that, a fan motor, a compressor mount or a compressor diagnosis all need the cabinet stripped and a meter on live terminals, which is where a service call starts.
