The short answer
Noises on the Costway BD refrigerator family are best diagnosed by location and timing rather than by description. A noise from the back that comes and goes with the compressor is one family of causes; a noise from inside the freezer that changes when you open the door is another; a rattle that stops when you press on the cabinet is neither.
What you see on the BD family
- A rhythmic ticking or scraping from inside the freezer — That is the evaporator fan blade touching frost, and the sound usually changes or stops when the door is opened.
- A click every few minutes from the lower back, then silence — The start relay trying and failing to start the compressor. This is the one noise on the list that needs attention quickly.
- A buzz or hum that has become noticeably louder — Often the condenser fan running against dust, or the whole cabinet resonating because it has shifted on its feet.
- A rattle that changes when you lean on the cabinet — Vibration transmitted into a cupboard, a wall or a drip tray. It is noise rather than fault.
Causes, most likely first on the BD family
- Cabinet resonance, levelling and the drip tray — Ranked first on the BD family — where the noise started after the unit was moved or cleaned behind, this is the change and nothing inside the machine has altered at all. A cabinet that has shifted on its feet rests against a cupboard or a wall and transmits ordinary compressor vibration into the joinery. A drip tray that has slipped its seat buzzes in sympathy.
- Condenser fan and a dust-loaded coil — Second — and it pairs with the cooling page: the same dust that makes this noise also makes the cabinet warm. The fan at the lower back runs whenever the compressor does, and dust on the blade or debris in its path makes it whine, buzz or tick.
- Evaporator fan blade catching frost — Third — the door test identifies it immediately and it points straight at a defrost problem underneath. Ice builds where it should not and the fan blade clips it once per revolution. The noise is rhythmic, it comes from inside the freezer, and it usually changes the moment the door is opened because the fan stops.
- Start relay or compressor — Fourth — a clicking relay with a warming cabinet should not be left running for days. A relay that cannot start the compressor clicks every few minutes as the overload cycles. A compressor with worn mounts or internal wear knocks or drones instead.
- Body: The order below is this family's rather than the brand's: with one build in the BD family the ranking is not an average diluted by chassis that fail differently, so the cause at the top is the cause that actually leads on BD-60-E.
Check in this order, and why
- 1. Stand still and locate the noise before anything else — Front, inside the freezer, or lower back. Location alone removes most of the list and it costs nothing.
- 2. Open the freezer door while the noise is happening — The evaporator fan stops with the door open on most cabinets, so a noise that vanishes is that fan and a noise that continues is not.
- 3. Lean gently on the cabinet and on the adjacent joinery — If the noise changes or stops, it is resonance rather than a failing part, and levelling the feet is the repair.
- Body: Because the BD family is one model, the access route below is the access route — there is no second layout to hedge against, which is exactly what the page above this one has to do.
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. A refrigerator is heavy and top-loaded when full, so empty the doors before pulling it out and keep it upright. Never put a hand near a fan blade to stop it or to feel for ice while the unit is plugged in.

When to call a technician
On the Costway BD refrigerator family the owner line is levelling, the drip tray, the coil and the frost check. Anything behind the freezer rear panel or at the compressor is not owner work, and a knocking compressor with a warming cabinet should be attended to rather than monitored.
