What this means on this family
When the AWCA line gets loud, the useful question is which noise it is making, not how loud it is. The table on this page covers a small group of model numbers in the same line. Some sounds on these cabinets are normal and one of them is urgent, so this page starts by separating the two.
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.
- Squealing or scraping that follows the fan speed — A bearing on its way out or a blade fouling its shroud. This one is a part, and it will get worse.
- A vibration you feel through the floor — The cabinet is transmitting normal compressor vibration into the structure, usually because a foot is not carrying its share.
- The cabinet rocks when a door is closed — A levelling fault with a noise attached. It also stresses the door seal, so it is worth fixing for two reasons.
- 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.
Causes, most likely first on the AWCA line
- Sounds the cabinet is supposed to make — First on the AWCA line, because more of these complaints end here than anywhere else. Gurgling as refrigerant settles, a trickle as melt water runs to the drain, cracks as the liner expands, and a change in tone as the compressor changes speed are all normal, and on a quieter cabinet they are simply more audible.
- The cabinet as a sounding board — Second. Any normal sound becomes a complaint when the cabinet amplifies it. A foot that is not down, a floor that flexes, or a side panel touching a cupboard will each turn a hum into a drone.
- Something touching a fan blade — Third. A rhythmic noise that keeps time with a fan rather than with the compressor belongs here.
- Bearings in either fan — Fourth, and the one item on this list that will definitely get worse if it is ignored.
- The compressor and its mounting — Last, and rarely the answer to a noise complaint on its own.
What to check first, and why that order
- Decide first whether the noise is a fault at all — Gurgling, trickling and cracking are normal. Establishing that saves the rest of the diagnosis.
- Check what is touching the cabinet — Walls, units, pipes, and anything stored on top. Free, fast, and the commonest real cause on cabinets of this size.
- Check the cabinet is level and every foot carries weight — A rocking cabinet turns the compressor into a loudspeaker.
- Listen at the freezer section with the door held open — Now worth doing: if the noise survives with the internal fan stopped, it is not the internal fan.
- Inspect the condenser fan with the power off — The last owner-side step, and the one that needs the machine moved.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before reaching behind any panel or near a fan — a capacitor can hold a charge after the power is off, and a condenser fan restarts without warning. If a noise comes with a burning smell or a hiss, do not investigate further — switch the machine off at the breaker and get it looked at, because neither of those is a mechanical noise. 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.
