The short answer
Most of the noises reported on the AFC refrigerators come from four places, and separating them is a matter of timing rather than of tools. On these models a fouled condenser fan is the first thing this page would have you rule out. None of the causes below needs a technician to rule out — only the repair might.
What you observe on these models
- A ticking or chirping from inside the freezer — It rises and falls with the fan rather than with the compressor.
- A low hum that is louder in the next room than in the kitchen — Structure-borne noise travels; airborne noise does not.
- A buzz that changes when you lean on a corner of the cabinet — The cabinet is carrying the noise, which makes it a mounting question.
- NEAR MISS — a hiss together with a chemical smell — Stop, disconnect the appliance and call a technician.
Causes, most likely first on this family
- Condenser fan blade fouled or out of balance — Because the condenser fan only runs with the compressor, a noise that comes and goes on a long slow cycle usually belongs to it. One design carries every cabinet size in this family, so it holds across the line.
- Ice maker fill and harvest mistaken for a fault — Switching the ice maker off for a day is the cheapest test there is, and it settles the question outright. It ranks second — the fault the first check leaves standing.
- Refrigerant flow heard after a defrost — A gurgle or a soft boil for a few minutes after a defrost is refrigerant redistributing, not a fault. Third: a real cause on these cabinets, but a less frequent one.
- Drain pan chattering in its rails — A pan noise is a light plastic rattle rather than a hum, and it usually stops if you press the pan down. Last, which is exactly why the checks above are worth spending first.
- Body: Because this family is one design at several capacities, the air path is the part that is worked hardest at the top of the ladder — which is what moves airflow causes above installation ones here.
Check in this order, and why
- Cut the power, take the rear cover off and turn the condenser fan by hand, feeling for roughness and for anything caught in the shroud. — First, because it settles the top of the ranking before anything else is touched.
- Switch the ice maker off for one day and note whether the noise you are chasing stops with it. — Next, once the check above has come back clean.
- Time the noise against the defrost cycle before spending anything: a sound that only follows a defrost is usually normal. — Last, so that nothing further is spent until the cheaper checks are exhausted.
Power down first, then work
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Nothing on the sealed system is owner work; those lines are under pressure. Do not reach into a running fan to find a noise. Cut the power, turn the blade by hand, and refit the panel before powering up.

When to call a technician
A noise you can place — a loose panel, a pan out of its rails, a cabinet off its feet — is an owner fix. One from inside the freezer or from the compressor is not. Disconnect and call for any burning smell.
