The short answer
Work out first whether the noise belongs to the ice maker cycle, because fill, harvest and cube drop are normal and alarming. Then the condenser fan behind the base grille, then the levelling. A scrape that stops when a door opens is the evaporator fan touching frost. The compressor is last.
What you observe
- A buzz then a clatter at random times — The ice maker filling and then harvesting into the door bin. Normal.
- A whirr from the base grille that rises and falls — The condenser fan, usually dusty rather than failing.
- A buzz you can feel through the floor — A wide cabinet not level or not in full contact.
- A scrape inside that stops when a door opens — An evaporator fan touching frost.
- NEAR MISS - a gurgle after the compressor stops — Refrigerant settling. Normal on any fridge.
Causes, most likely first on this brand
- The ice maker running its normal cycle — First, and it is not a fault. A fill buzz, a freeze period and a clatter of cubes into a door bin are what a working ice system sounds like, day and night.
- A dusty condenser fan — Second. The fan behind the base grille collects dust and pet hair at floor level until the blade is unbalanced and whirrs.
- A cabinet not level or not in contact — Third. These are wide and heavy, and a foot barely touching sends compressor vibration into the floor rather than keeping it in the machine.
- Frost touching the evaporator fan — Fourth. A scrape that stops when a door opens is that fan, and on an automatic-defrost cabinet it points at the defrost system too.
- A worn fan motor or a failing compressor — Last. A fan noisy after cleaning is a part; a loud clunk at start with a warming cabinet is urgent.
Check in this order, and why
- Note whether the noise repeats on a cycle — Regular intervals day and night usually means the ice maker.
- Turn the ice maker off for a day — If the noise stops, you have confirmed it for nothing.
- Open a door while the noise is happening — The evaporator fan stops on the door switch.
- Rock each corner and check the feet — A wide cabinet out of level buzzes through the floor.
What an owner can safely check
- Listen through a full ice maker cycle — Fill, freeze and harvest each sound different and all are normal.
About 30 min
- Remove the base grille and clean the condenser and fan — Vacuum gently along the fins and clear the fan area.
Tools: vacuum, soft brushAbout 30 min
- Level the cabinet and set the feet — Adjust until it does not rock and both doors close on their own.
Tools: spirit level, adjustable wrenchAbout 25 min
- Clear frost from around the evaporator fan — Switch off and let it melt rather than chipping it away.
Tools: towels, cool boxAbout 240 min
- STOP HERE if a clean fan is still noisy — That is a fan motor.
Before you open anything
Safety
Unplug the refrigerator before removing the base grille or reaching into the condenser area, because the fan, the auger and the ice harvest can all operate at any time while it has power. Condenser fins are sharp - wear gloves. Never chip frost off an interior surface with a knife or a screwdriver, and get help to move a wide cabinet rather than walking it across a finished floor.
When to call a technician
Call when the noise is not part of the ice maker cycle, the condenser and fan are clean, the cabinet is level and a whirr, scrape or knock persists - especially if frost returned, which points at the defrost system as well as the fan. Call without further testing if the compressor clunks at start and the cabinet is warming, or if it starts and stops every few seconds.

What this page does not cover
This page covers the Cafe freestanding French-door refrigerators, which stand clear of cabinetry and drop ice into a door bin. The built-in cabinets are fixed into joinery and breathe through a top grille, which changes what you hear and where from; the sibling page linked below covers those. Not included: fan and compressor part identifiers, sound ratings and refrigerant data.
