The short answer
This platform has an ice maker as standard, and a harvest dropping into a bin inside a built-in cabinet is the loudest thing it does. Ranked first on this platform: An ice maker cycling. The checks below follow that ranking, and the first of them need no tools and no panel removed.
What you observe
- A bang a few times a day rather than a continuous noise — A periodic event matches a cycle, not a failure.
- Ticking that arrives with the compressor and leaves with it — A noise tied to the cycle belongs to something that only runs during it.
- A rhythmic scraping that gets louder when the door is open and the switch held — A noise that responds to the door switch is inside the compartment.
- NEAR MISS — a gurgle, a trickle or a soft tick a few minutes after it stops — Refrigerant settling and metal contracting are normal on every cabinet and no repair removes them.
Causes, most likely first on this platform
- An ice maker cycling — A freezer with an automatic ice maker fills, freezes and drops cubes into a bin several times a day, and the drop is a bang. It ranks first on this platform because cubes falling into a bin several times a day inside a sealed column sound structural from a quiet kitchen, and switching the ice maker off for a day settles it without touching a tool.
- The condenser fan fouling on debris — The fan at the back or underneath runs in the dust. 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.
- The evaporator fan catching frost — A tongue of frost growing out towards the fan blade gives a rhythmic scrape or a buzzing rattle that speeds up and slows down with the fan. It comes third in the order — a genuine cause here, behind the ones above it on frequency alone.
- The cabinet touching a wall, a pipe or the next unit — Freezers are pushed into corners and utility rooms where there are pipes, shelving brackets and neighbouring cabinets to touch. It ranks fourth rather than higher: real on this platform, and less common than the causes above it.
Check in this order, and why
- Switch the ice maker off for a day and listen — One switch, one day, a complete answer. It leads because it tests the top-ranked cause.
- Listen at the lower grille as the compressor starts — Timing places it at the machine compartment. Tests the second-ranked cause.
- Hold the door switch in and listen at the rear panel — It localises the noise to the fan compartment in one move. Tests the third-ranked cause.
What an owner can safely check
- Lift the bail arm or switch the ice maker off for twenty-four hours — If the bangs stop, nothing needs repairing.
About 10 min
- Unplug the cabinet and clear the compartment with a vacuum and a brush — Never spin a blade by hand with the appliance plugged in.
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 putting a hand near a fan — a capacitor can hold a charge after the power is off, and a fan stopped by an open door will restart without warning.
When to call a technician
Call when the noise is behind a sealed panel, or when it is a hard knock at the instant the compressor starts.

What this page does not cover
This page is written for the Monogram freezer 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.
