The short answer
Most new refrigerator noises are the cabinet telling you about its installation rather than about a failing part. On a compact cabinet the ranking below follows how the cabinet is built and where it usually sits, and the top two causes cost nothing to rule out.
What you observe
- A hum or drone from the bottom or back — The compressor or the condenser fan, which is the only part of the cabinet that should hum continuously.
- Clicking every few minutes with no cooling change — A start relay trying and releasing, or a defrost timer stepping.
- NEAR MISS: gurgling and ticking after the cabinet cycles off — That is refrigerant settling and metal contracting.
Causes, most likely first on this cabinet
- The cabinet is not level or not standing solid — A foot slightly off the floor turns the compressor hum into a rattle through the whole cabinet. Ranked first on Danby Premiere: a compact cabinet has little of everything - little thermal mass, a shallow condenser, a small drain and almost no clearance - so the first thing to go wrong is nearly always whatever its installation is asking too much of, and a frost-free cabinet with a separate freezer compartment has an air path between the two that a single-door unit does not.
- Something touching the cabinet or sitting on it — A drip tray, a wall, a cabinet side, a bottle on top or a coiled water line all turn a normal vibration into a noise. Ranked second: it ranks below the causes above because it costs more effort, not because it is rare.
- The evaporator fan behind the freezer panel — A worn bearing chirps or squeals, and a blade brushing frost clatters. Ranked third: it sits here because it produces the same complaint as the cause above it and takes longer to confirm.
- The compressor or its mounts — Rubber mounts harden with age and let the compressor case drum against the frame. Ranked last: it is last because on an appliance this size the major components outlive everything around them, and replacing one often costs more than the appliance is worth.
Check in this order, and why
- Push each top corner of the cabinet in turn — Any rock at all means a foot is short, and that alone explains most new rattles.
- Pull the cabinet clear of the wall and run it — If the sound goes, you have found it.
- Open the freezer and hold the door switch in — The sound rising as the fan spins up puts it here rather than anywhere outside the box.
What an owner can safely check
- Level the cabinet and set both front feet down solid — Adjust the feet until there is no rock at any corner, with a very slight backward tilt so the doors swing closed.
Tools: adjustable wrenchAbout 15 min
- Pull the cabinet out, clear the top and re-seat the drip tray — Leave the specified clearance at the back and check that no water line or cord is pressed against the cabinet skin.
About 10 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before taking off any panel or reaching behind the rear grille, and keep it off while your hands are inside: a capacitor can hold a charge after the power is off, and a condenser fan can start without warning. Do not hold a freezer door switch in with tape and then leave the cabinet unattended.
When to call a technician
Call when the noise comes with a loss of cooling, when it comes from behind a panel you would need to remove, or when it is a hard metallic knock rather than a rattle or a hum. A noise on its own, with the cabinet still holding temperature, is rarely urgent.

What this page does not cover
This page covers the Danby Premiere refrigerator as a class, not one model or production run. Any family- or model-specific page for your unit takes precedence over it. Not here: part numbers for fan motors and mounts, and the disassembly sequence for your specific cabinet, both of which vary by model line.
