The short answer
A FKATMP refrigerator that has become noisy is usually still working correctly — the noise is a bearing, a blade touching ice, or a cabinet passing its own vibration into the floor. This family spans a pair of model numbers rather than a range. Very few noises on these cabinets mean the machine is failing.
What an owner actually sees
- The noise only happens at night — Almost always a room that has gone quiet rather than a machine that has changed. Worth establishing before anything is opened.
- A loud buzz or rattle from the back that stops when you touch the cabinet — Resonance, not a failing part. Something at the back is vibrating against the cabinet or the wall.
- A sharp crack or pop at intervals — Plastic and metal expanding and contracting as the cabinet changes temperature, most obvious during and after a defrost cycle.
- A single loud bang or knock at long intervals — Thermal movement of the liner or a duct, usually around a defrost cycle. It sounds alarming and is not.
- NEAR MISS — the noise arrived with a warm cabinet — Then the noise is a clue in a cooling failure, and the cooling page for this family is the right place to start.
Ranked causes for these models
- Levelling and cabinet contact — First on the FKATMP family. Cabinets of this build are light relative to the vibration their compressor produces, so anything that turns the cabinet into a sounding board is heard immediately. A foot not carrying weight, a side touching a unit, or a back touching a pipe all produce a noise the owner describes as mechanical.
- Loose items on top of or behind the cabinet — Second, and it is worth a deliberate check rather than a glance — the item responsible is usually one nobody thinks of as being in contact with the cabinet.
- Condenser fan and debris — Third. Confirmed with the power off and a torch, and cleared without tools most of the time.
- The internal fan against frost — Fourth. It is the cause that ties a noise complaint to a cooling complaint, so note whether the cabinet temperature has drifted as well.
- The compressor itself — Last. A genuinely failing compressor is uncommon and rarely announces itself with noise alone — there is usually a cooling failure alongside it.
The order to work in on these models
- Locate the noise before doing anything else — Inside the cabinet, behind it, or under it. Three locations, three separate halves of the list.
- Note whether it keeps time with a fan or with the compressor — A rhythm that matches a fan is an obstruction; a steady hum is the compressor or a mount.
- Open the door and listen again — On most cabinets that stops the internal fan, so a noise that disappears has just named itself.
- Lean on each corner of the cabinet in turn — A noise that changes under hand pressure is resonance, and it needs a spirit level rather than a part.
- Pull the cabinet out and look at the back with the power off — Last because it is the most work, and by this point you know whether the noise is even back there.
Before any panel comes off
Safety
Isolate the cabinet before any cover or grille comes off; a capacitor can hold a charge after the power is off. The compressor and the tubing around it can be hot enough to burn immediately after running, and the fins at the condenser are sharp. Never defeat a door switch to keep an internal fan spinning while you look at it. A noise complaint on its own does not put food at risk, but check the temperature while you are there: a refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below.

Where owner work stops
The boundary on these models is the panel. Levelling, clearing debris, removing ice and stopping something touching the cabinet are all owner-side. A fan motor, a compressor mount or anything that needs the evaporator cover off is a service call. Call at once if the noise is accompanied by a smell, because that changes the question from noise to safety.
