The short answer
A noisy BestHome under-counter refrigerator is most often touching the worktop or the units beside it, or running far more than it should because its front grille is blocked. Both are free to correct. A rhythmic tick that stops when the door opens is the internal fan, and a click every few minutes with silence afterwards is the compressor.
What you observe
- A hum that seems to come from the worktop — The cabinet is touching the counter and passing vibration into it.
- A buzz that changes when you press the plinth or the grille — A loose grille or plinth panel rather than the appliance.
- A tick from inside that stops when the door opens — The internal fan striking ice, which is a cooling problem.
- NEAR MISS — a click every few minutes then silence — The compressor cutting out on its overload, which needs attention.
Causes, most likely first on this brand
- Contact with the worktop or the neighbouring units — First on a built-under cabinet: the clearances are small, and any contact turns an ordinary compressor into a sounding board the width of the kitchen.
- A loose front grille or plinth panel — Second, and specific to this format. Both are fitted on site, both work loose, and both buzz at exactly the compressor's frequency.
- A blocked front ventilation grille — Third: a built-under cabinet takes its air in and out at the front, and a grille matted with dust makes it run for far more of each hour. The sound is the same; you simply hear it constantly.
- Ice in the fan path, or the compressor — Last. The door-open test separates them, and a click with silence afterwards is a fault rather than a noise complaint.
Check in this order, and why
- Press on the worktop and the neighbouring units while it hums — A noise that changes under your hand is contact, not the appliance.
- Check the grille and plinth fixings — Both are common loose parts on a built-under installation.
- Pull the grille and look at the airflow path — A blocked grille explains a cabinet that never seems to stop.
- Open the door during the noise as a final test — A noise that stops instantly is the internal fan.
What an owner can safely check
- Check the cabinet is not touching the worktop or units — Adjust the feet so it sits clear on all sides.
Tools: spirit level, spannerAbout 25 min
- Tighten the grille and plinth fixings — A single loose fixing is enough to buzz.
Tools: screwdriverAbout 15 min
- Remove and vacuum the front grille — Clear the mesh and the space immediately behind it.
Tools: vacuum, soft brushAbout 20 min
- Confirm the appliance is level in its opening — A cabinet that rocks in its housing transmits far more.
Tools: spirit levelAbout 20 min
- STOP HERE if it clicks and falls silent — Compressor and relay work is a service call.
Before you open anything
Safety
Unplug the cabinet or switch it off at its breaker before removing the grille or any interior panel — a capacitor can hold a charge after the power is off. Take care drawing a built-under appliance forward: the worktop above limits how far it will tilt, and the door makes it front-heavy. Never chip ice from an evaporator, and never re-route tubing to silence a rattle.
When to call a technician
Call when the cabinet is clear of the worktop and the units, the grille and plinth are tight and clean, and the noise persists. A tick that returns within days of a defrost means the defrost system rather than the fan. Call promptly for a click every few minutes with silence afterwards, because that is the compressor cutting out and the cabinet will warm.

What this page does not cover
This page covers BestHome under-counter refrigerators as a class rather than one model line. Deliberately absent here, because they differ by family: niche and clearance dimensions, grille specifications, fan and compressor part identifiers and capacity figures.
