The short answer
Most refrigerator noise comes from one of three fans and pans rather than from the compressor, and the timing of the noise tells you which. A noise that starts when the door closes is different from one that runs all the time. Open the freezer door and hold the light switch in. If the noise changes or stops, it is the evaporator fan behind the rear panel; if it continues unchanged, it is at the back of the cabinet. On a Smeta refrigerator the cause that ranks first is drain pan or a cover panel rattling.
What you observe
- A repeated click every few minutes with no compressor run — The start relay, and this one is a warning rather than a nuisance.
- A tick or scrape that changes when the freezer door is opened — The evaporator fan behind the rear panel.
- NEAR MISS — the noise arrived with the cabinet getting warm — Then treat it as a cooling fault, which is the more urgent page.
Causes, most likely first on a Smeta refrigerator
- Drain pan or a cover panel rattling — The evaporation pan sits loose under the cabinet by design, and a pan that has shifted buzzes against the compressor mount. It ranks first on a Smeta refrigerator because there is very little slack behind the panels of a compact cabinet, so anything that restricts restricts completely.
- Condenser fan hitting debris in the plinth — The fan beside the compressor draws in dust, paper and pet hair, and a scrap caught in the blade gives a loud intermittent flutter. Second on this platform: anything that falls under a cabinet ends up at that fan, and a shallow plinth collects more of it.
- Evaporator fan blade catching frost — Frost builds on the shroud behind the freezer panel and the blade ticks or scrapes against it, loudest just after the door has been open. Ranked here because it is the noise that changes when the freezer door is opened, which no other cause does.
- Cabinet not level, drumming on the floor — A cabinet standing on three feet transmits every compressor vibration into the floor, and the floor is louder than the appliance. Ranked here because the stance is free to correct and it is behind more noise complaints than any component.
- Compressor start relay buzzing or clicking — A relay that clicks repeatedly every few minutes is trying and failing to start the compressor, and it is a warning rather than a noise complaint. Last, and the reason to work down the list rather than guess: a repeated click every few minutes is a different problem from a rattle and it needs attention sooner.
Check in this order, and why
- Press gently on the lower rear panel while the noise is happening — A noise that changes under hand pressure is a loose panel or pan.
- Unplug the cabinet and look into the plinth or the back with a torch — Debris in the blade path is visible and free to remove.
- Open the freezer and hold the door switch in, listening for the noise to change — A noise that stops with the door open is the evaporator fan.
What an owner can safely check
- Unplug the cabinet and re-seat the drain pan squarely in its brackets — Empty and rinse it while it is out.
Tools: torch, clothAbout 15 min
- Unplug the cabinet, clear the plinth or rear grille by hand and vacuum the area — Never reach into a blade path with the cabinet plugged in.
Tools: vacuum, torch, gloveAbout 20 min
- STOP at the point where the next check means live terminals or a panel removed — Everything past that line is a technician's work, however likely the cause above it looks.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before reaching into the plinth, behind the cabinet or near any fan blade — a capacitor can hold a charge after the power is off.
When to call a technician
Call once the plinth, the pan and the stance are ruled out and the noise is still there, and sooner if the cabinet is also failing to hold temperature. On a nameplate like this, confirm parts availability before agreeing to a repair: the platform is common, but the badge is not always supported locally.

What this page does not cover
What this page covers is the refrigerator class as Smeta builds it, not an individual family or model line. If a page exists for your particular family or model, it is linked above and it is the better answer — go there first when your model is named. Left out on purpose: part numbers, connector colours, disassembly order and torque values, because every one of those varies by family.
