The short answer
The order that matters here is a small cabinet with nothing to absorb vibration first, the evaporator fan catching ice next and the ice maker and its fill valve last. On a compact import-channel unit the surroundings come first. There is very little mass and very little margin in these machines, so where one stands changes how it behaves. That ranking is the value of this page: the cheap causes are the common ones on Shomson refrigerators, and the costly one is what people reach for first.
What you observe
- A rattle that changes when you touch the cabinet — Something loose rather than something failing — a drain pan, a rear panel or a bottle inside.
- A loud buzz for a few seconds, then silence — The water valve filling an ice maker, which does this on a schedule whether or not it makes ice.
- Clicks, cracks and pops at intervals — Plastic and metal moving as the cabinet changes temperature. This is normal and is not a fault.
- NEAR MISS — noise only when the ice maker runs — The fill valve and the harvest cycle are both loud by design.
Causes, most likely first on Shomson
- A small cabinet with nothing to absorb vibration — On a small unit the surface underneath matters more than anything inside. The same appliance can be almost silent on a solid floor and clearly audible on a hollow worktop or a wooden shelf. Top of the list for this brand: on a compact unit the surface underneath leads, because there is no mass in the cabinet to damp anything.
- The evaporator fan catching ice — This is the noise that means something. Second here: the door test separates it from everything else in seconds, and it is the noise most likely to be telling you about a second fault behind it.
- Noises that are supposed to happen — Modern refrigerators make sounds their predecessors did not: the crack of plastic contracting during defrost, the trickle of refrigerant after the compressor stops, the buzz of a fill valve, the drop of ice into a bin. Third on this brand: it belongs on this list because a normal noise correctly identified saves an unnecessary service call.
- The ice maker and its fill valve — An ice maker is a noisy device by design: the valve buzzes as it fills, the mould heats and releases, and the cubes drop into a bin that acts as a drum. Last, and the placement is the point: this ranks where it does because the noise is loud, alarming and almost always working as designed.
Check in this order, and why
- First: Move it to a different surface — A unit that goes quiet on a solid floor has named its support rather than its parts. It is first because it is the cheapest of the three to settle.
- Second: Open the freezer door while it is noisy — If the noise stops the instant the door opens, it is the evaporator fan and nothing else.
- Third: Does it happen on a schedule? — A short noise at intervals, with normal cooling, is part of how the appliance works.
What an owner can safely check
- Stand the unit on a solid, level surface — Move it off any hollow shelf or worktop, level it, and listen again after it has run for an hour.
About 20 min
- Listen at the freezer with the door open and closed — Note whether the noise stops with the door open. Do not force the rear panel off.
About 10 min
- STOP HERE if the next step needs a meter on live terminals — That is the line between an owner check and a service call, and it is not worth crossing.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel, and treat every capacitor as still charged: a capacitor can hold a charge after the power is off. Secure or remove the doors before moving a unit, get help with the lift, and never lay a refrigerator on its back. Do not put a heat gun anywhere near a cabinet full of plastic.
When to call a technician
Everything above that is done with a vacuum, a torch and a spanner is owner work. Past that, the panels come off and the unit has to be isolated first.

What this page does not cover
This is generalized information for Shomson refrigerators as a class, not for one family or one model. No family- or model-specific page for this brand and appliance is published here yet, so nothing narrower is linked; when one is, it becomes the more specific answer and this page will point to it. No part numbers, no wiring detail, no dismantling sequence: those vary by family and are only useful beside the family they describe.
