The short answer
This platform has an automatic ice maker as standard, and the single most reported "new noise" on a built-in cabinet is that ice maker doing its job. Ranked first on this platform: The ice maker running its cycle. The checks below follow that ranking, and the first of them need no tools and no panel removed.
What you observe
- A bang or clatter a few times a day rather than a continuous sound — A periodic event a few times a day matches the ice cycle, nothing else.
- The noise starts and stops with the compressor rather than running continuously — A sound tied to the cycle belongs to something that only runs during the cycle.
- The noise is louder standing beside the cabinet than in front of it — Sound that comes from the side is coming from the contact, not the compressor.
- NEAR MISS — the noise is a gurgle or a trickle a few minutes after the unit stops — Refrigerant settling and defrost water running are normal sounds on almost every cabinet, and no repair will remove them.
Causes, most likely first on this platform
- The ice maker running its cycle — An automatic ice maker fills, freezes, twists its mould and drops cubes into a bin, and the drop is a bang. It ranks first on this platform because a harvest drops cubes several times a day into a bin inside a sealed built-in cabinet, and from a quiet kitchen that bang sounds like something structural failing when it is the machine working.
- The condenser fan blade fouling on debris — The fan under or behind the cabinet runs in the dustiest part of the room. It ranks second here because the whole condenser airflow for a built-in comes and goes through the toe-kick grille, which is at floor level where dust, pet hair and the vacuum cleaner all live.
- Something the cabinet is touching — A cabinet that touches the wall, a worktop edge, a pipe or the next unit along transmits vibration straight into it, and the surface it touches is usually louder than the appliance. It sits third because the causes above it account for more of these cases, not because it is unlikely.
Check in this order, and why
- Turn the ice maker off for a day and see whether the sound stops — One switch, one day, complete answer. It leads because it tests the top-ranked cause.
- Listen at the lower grille or the back, and watch for the noise to arrive with the compressor — It places the noise at the condenser compartment without anything coming apart. Tests the second-ranked cause.
- Ease the cabinet forward a couple of inches and listen again — If the noise leaves with the contact, the diagnosis is finished. Tests the third-ranked cause.
What an owner can safely check
- Lift the ice maker bail arm to the off position for twenty-four hours — If the noise disappears, nothing needs fixing at all.
About 10 min
- Unplug the cabinet and clear the condenser compartment with a vacuum — Take the lower grille off if it unclips by hand.
Tools: vacuum, soft brushAbout 25 min
- STOP before anything behind a fixed panel, and note what each check showed — Everything past this line is measured rather than looked at, and measuring it safely needs the power off and a meter.
Before you go looking for the source
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching behind a fan — a capacitor can hold a charge after the power is off, and a fan blade that has stopped because you opened a door will start again without warning.
When to call a technician
Call once the noise has been traced to something behind a sealed panel, or once it is clearly coming from the compressor itself rather than from anything touching it.

This page is written for the Monogram refrigerator as a class, not for one family or one model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and the one to read first. Deliberately not here: part numbers, wiring colours and disassembly order, which differ by family.
