The short answer
Most ARBA noise complaints turn out to be a healthy machine amplified by what is around it, or something loose inside the cabinet, rather than a failing compressor. On a compact manual-defrost refrigerator the sound has a short path to you and the usual sources are all reachable. The start relay and the drip tray produce more noise complaints on a compact than the compressor ever does. There is one number under the ARBA label in the table below, so nothing here depends on which variant you own.
What you observe on these models
- A click, a short buzz and then silence, repeating every few minutes — The start relay trying and the compressor not starting, and it is the signature noise of a compact.
- The noise started after the cabinet was moved — Levelling and contact with cabinetry, before anything internal.
- A buzz that comes from the back at floor level — The machine compartment: tray, tubing or fan, all visible in a minute.
- A buzz from the back that stops when you press on the drip tray — The tray is off a lug and resonating with the compressor.
- NEAR MISS — a loud buzz that coincides with the cabinet no longer cooling — That is a starting fault and the cooling page is the right one to read first.
Causes, most likely first on the ARBA family
- Start relay clicking and the compressor buzzing on attempt — First on this platform: a sharp click every few minutes with a short buzz and no cooling is this cause almost every time.
- The drip tray or a loose back panel rattling — Second: the tray sits on the compressor and is held by lugs; once it is off one lug it buzzes with every compressor cycle.
- Panel and shelf rattle inside the freezer compartment — Third: ice trays and wire shelves vibrate against a thin liner.
- Bottles and cans vibrating against each other and the racks — Fourth, and the easiest to confirm: empty one shelf and listen again.
- Cabinet resonance in a bar or island surround — Last: built-in cabinets couple their compressor vibration into the joinery around them.
Check in this order, and why that order
- Listen for a click, a buzz and then silence, repeating every few minutes — That pattern is the start relay and the compressor failing to start, and it is the most common noise complaint on a compact.
- Pull the cabinet and press on the drip tray and the back panel — A tray off its lug buzzes in time with the compressor and goes silent under a finger.
- Take out the ice trays and loose shelving from the freezer side — Thin liners and wire shelves rattle convincingly.
- Pull the cabinet and check the condenser fan and the tubing — Both are in the same compartment at the back and both are easy to see.
- Decide whether the noise follows the compressor cycle — If it does not, it is not the compressor, however much it sounds like it.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Treat that as the first step of every check below that involves a panel, a grille or a cover.

When to call a technician
Anything you can silence from outside the cabinet on a compact manual-defrost refrigerator, unloading a shelf, clearing a fan, lifting a tube, levelling a foot, is yours. On these models the line falls at the rear panel and the sealed refrigerant circuit. Call without working through anything at all for a compressor that knocks hard enough to move the cabinet, or any smell of burning.
