Does this apply to every USBSR model?

It applies to the models listed in the table on this page. Where one differs, the difference is in access rather than in the ranking of causes.

Can I fix this myself?

Often. A shifted drip tray, loose panel screws, a cabinet out of level and debris in the condenser area between them account for most new noises, and all four are free.

Why is it louder at night?

Usually because the kitchen is quiet, not because the appliance has changed. If the noise is genuinely worse at night, the room temperature and a longer run cycle are the reason.

Does levelling really change the noise?

It does. A cabinet on three feet transmits compressor vibration straight into the floor, and a floor is a much better loudspeaker than a refrigerator.

Could the noise be the ice maker?

Yes, and it has a signature: a buzz on a schedule lasting well under a minute. That is the fill valve, and it is only a fault if no water arrives.

Bangson USBSR Refrigerator: Abnormal Noise or Vibration

Sarah Chen·Lead Appliance Repair Technician

2026-09-24·8 min read·EPA 608 Universal

Table of Contents

What this usually means

USBSR models take this one slightly differently. The useful first question is whether the noise is constant or intermittent. A constant noise is a fan or a compressor; an intermittent one is a cycle — defrost, ice maker, or a compressor trying to start and failing. The departure from the generic page is in where the first check goes.

What you observe on a USBSR unit

A noise that stops the moment the freezer door opens — That is the fan being cut by the door switch, which is the appliance behaving exactly as designed. On these USBSR models it is the observation that decides the order.
A click every few minutes followed by silence — A start relay trying and failing to bring the compressor up, which is the one noise on this list that needs attention soon.
Buzzing that arrives on a schedule and lasts under a minute — The ice-maker fill valve doing its job. It is only a fault if the water is not arriving.
A new noise that started the week the appliance was moved — A shifted drip tray, a bent fan guard or a cabinet now standing on three feet instead of four.
NEAR MISS: water is on the floor as well — A rattling drip tray and a leak are neighbours; if there is water, start on the leak page.

Causes in likelihood order on the USBSR line

A worn evaporator fan motor or a blade catching ice — Ranked first because it is both the most common and the easiest to localise: the noise changes when the freezer door opens, and nothing else on this list does that. On the USBSR models this stays at the top because nothing about the platform makes it less likely.
Loose rear panels or a fan guard touching a coil — Screws back out over years of vibration, and the panel then buzzes in sympathy with the compressor.
A failing compressor mount or an internal compressor fault — Last, and deliberately so: it is the least likely cause of a new noise and the only one that is not an owner check. A knocking that survives every other check is where it enters the conversation.

Where to start, and why

Open the freezer door and listen for the change — Louder means the evaporator fan; unchanged means the noise is not in that compartment. One action, and the list halves. The USBSR layout is the reason it comes first here.
Press gently on the rear panel while the noise is happening — A noise that stops under a hand is a loose panel and nothing more.
Check whether the noise started after a defrost — Cracks and pops that follow a defrost cycle are thermal and normal.
Note whether the noise runs on a schedule — Something that arrives for a few minutes every hour or two is almost certainly a normal cycle.

Isolate it first

Safety

Disconnect power before a screwdriver touches a panel. A refrigerator is heavy and awkward: empty it before moving it, walk it rather than drag it, and keep fingers out from under it when settling it back onto its feet.

When to call a technician

Stop at the point where a panel inside the freezer has to come off. Call then. Call urgently if you smell anything hot at the back of the appliance, or if the unit trips its breaker when the noise happens.

Frequently Asked Questions

Does this apply to every USBSR model?: It applies to the models listed in the table on this page. Where one differs, the difference is in access rather than in the ranking of causes.
Can I fix this myself?: Often. A shifted drip tray, loose panel screws, a cabinet out of level and debris in the condenser area between them account for most new noises, and all four are free.
Why is it louder at night?: Usually because the kitchen is quiet, not because the appliance has changed. If the noise is genuinely worse at night, the room temperature and a longer run cycle are the reason.
Does levelling really change the noise?: It does. A cabinet on three feet transmits compressor vibration straight into the floor, and a floor is a much better loudspeaker than a refrigerator.
