The answer first
Most alarming refrigerator noises come from moving air, moving ice or a cabinet that is not sitting square. Most of this is diagnosis by ear, and the fixes are usually free. On this kind of cabinet this is a high-volume budget line from a major maker, so the design is conventional and the wear points are the conventional ones.
The signs, and the near misses
- Cracking and popping after the cabinet has been quiet — Plastic and metal moving as temperatures change; normal in every frost-free cabinet.
- A grinding or scraping that rises and falls — A fan blade catching ice or a worn bearing; the sound tracks the fan and not the compressor.
- A buzzing or humming that changes when the freezer door opens — That is the circulation fan being switched by the door — the most diagnostic observation available.
- NEAR MISS — a rhythmic clunk only when ice drops — That is the ice maker harvesting and it belongs on the ice-production page if it seems wrong.
What is usually behind it
- Evaporator fan blade catching frost or a bent shroud — Ranked first: It is confirmed at no cost: hold the door switch in and listen, then release it and hear the noise stop. It sits at the top here since this is a high-volume budget line from a major maker, so the design is conventional and the wear points are the conventional ones.
- Condenser fan obstructed or bearing worn — Second: Bearings dry out with age and announce it as a whine that rises with room temperature.
- Cabinet not level or resting on an uneven floor — Third: A cabinet standing on three feet drums against the floor every time the compressor starts, and it sounds far worse than it is.
Working through it
- Run a hand along the door seal line with the door shut — Cold air escaping at a point is felt before it is seen, and it accounts for several unrelated-looking complaints.
- Rock the cabinet gently corner to corner — Any movement means it is standing on three feet, and that alone can produce a drumming rattle.
- Pull the cabinet out and look behind it with a torch — Tubing touching the shell, a displaced pan or a toy under the unit all show themselves right away.
The owner procedure
- Clear the lower grille and the condenser fan area — Unplug first, then vacuum the grille and remove anything that has fallen behind it.
Tools: vacuum, torchAbout 20 min
- Level the cabinet and confirm all four feet carry weight — Adjust the front feet until the unit does not rock and sits very slightly back.
Tools: spirit level, adjustable spannerAbout 20 min
- Run a manual defrost if the noise suggests fan-on-ice — Empty the cabinet, unplug it and leave the doors open; a grinding that disappears afterwards confirms the diagnosis.
Tools: towelsAbout 30 min
- STOP before any electrical testing — Hand over here: the remaining checks need an instrument and an isolated appliance.

Safety
Pull the plug, or trip the breaker that feeds the outlet, before any panel comes off; a stored charge can sit in a capacitor long after the lights go out. Sealed-system work — the compressor, the condenser and the lines between them — belongs to a licensed technician with recovery gear. Nothing in the sealed circuit is an owner job: it is pressurised, and the law treats venting it as a violation in its own right.
When to call a technician
Book a visit if the sound is accompanied by the cabinet losing temperature: the noise is then a symptom and the cooling loss is the job. Levelling, cleaning and clearing obstructions are owner work; replacing a fan motor is not. Bring the technician your notes rather than your theory; what you observed is worth more than what you concluded.

Scope of this page
The page is deliberately family-agnostic: one Comfee refrigerator can share nothing with the next but the badge. Where a family- or model-specific page exists for your cabinet, it is the more specific answer and it is linked from the pages listed here — start there if your model appears by name. The family- and model-specific pages linked here do, and where one covers your unit it is the better starting point. It says nothing about accessory kits or aftermarket conversions, which change the behaviour described above.
