The short answer
A new noise on the AFB refrigerators is nearly always something being shaken rather than something failing, and when it happens tells you which. On these models a fan blade striking frost is the first thing this page would have you rule out. The checks below are all owner-side; what they buy you is a named cause before anyone is paid.
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 — the noise came with the box going warm — Treat it as a cooling fault first; the noise is the symptom, not the cause.
Causes, most likely first on this family
- Evaporator fan blade striking frost — A blade that touches ice makes a hard ticking or a chirp that rises as the fan speeds up with the door closed. It leads because it is the likeliest of the set on these cabinets. This family is a single build, so it holds across the line.
- 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. Second: common enough on these models to come before anything below it.
- Supply tubing pressed against the cabinet — Adding a loop of slack costs nothing and takes away the path the noise was using. Third on the list, where the likelihoods start to fall away.
- Defrost timer or damper motor stepping — A mechanical timer clicks as it steps and a damper motor drives its flap with a short whirr; both are normal and both worry owners. Last of the set listed here, and the least likely of them on this family.
- Body: The departure from the brand-wide ranking is that installation causes outrank wear ones on this page — a single build puts a narrow age band in service, and fitting faults do not wait for age.
Check in this order, and why
- Hold the freezer door switch closed and listen: a fan striking ice ticks in time with its own rotation. — It comes first because it matches the cause ranked first above.
- Cut the power, look under the back of the cabinet and seat the pan properly in its rails. — Next in order, following the ranking rather than convenience.
- Follow the water line from the valve to the cabinet and free it from anything it is pressed against. — Last of the set, and only worth doing once the others are clean.
Cut the power before anything else
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. A loaded cabinet is heavy and top-heavy with the doors open, so empty it and get help before moving it. 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.
