How long will food stay safe while I wait?

A closed refrigerator holds a usable temperature for a few hours and no longer once it has stopped cooling. Move perishables to a cooler with ice and keep the door shut.

The freezer is fine but the fridge is warm. Is that one fault?

Usually yes, and it is an air-transfer fault rather than a cooling fault. The damper or the fan that moves air between the compartments is the first suspect.

Should I defrost it manually?

It is a reasonable test. Empty the cabinet, switch it off, leave the doors open for a day, and restart it. If it cools well and then fails again within a week, defrost is the fault.

Can a dirty condenser coil really stop it cooling?

Yes. The coil is how the heat leaves; blanket it in dust and the system runs continuously without ever reaching temperature. It is the cheapest fix on the list.

Is it worth repairing or should I replace it?

It depends entirely on which cause it turns out to be. Defrost parts, fans and gaskets are modest repairs; a sealed-system fault rarely is. Get the cause named before deciding.

Bangson USBSR Refrigerator: Not Cooling or Not Freezing

Sarah Chen·Lead Appliance Repair Technician

2026-09-23·8 min read·EPA 608 Universal

Table of Contents

The short answer

When the USBSR line stops cooling, the useful split is whether the freezer side is still cold. Freezer cold and fresh food warm is an air-transfer fault and is often cheap; both compartments warm with the compressor running points at defrost or at the sealed system. Move anything perishable to a cooler first — a refrigerator holds food safely at 40 °F (4 °C) or below. The name covers a long run of model numbers, so treat the ranking below as the pattern for the platform and the table as the authority on which machine you actually have.

What you observe on these models

The back of the cabinet is hot and the cabinet is warm — Heat is being rejected badly — a choked condenser or a stopped condenser fan will produce exactly this.
It cooled again after being switched off overnight, then failed within a day — The classic defrost signature: melting the ice restores airflow temporarily and the fault returns as the ice rebuilds.
The cabinet is warm but the unit is clearly running — A steady compressor note with no cold air at the vents — the cold is being produced somewhere and not arriving.
The freezer is still cold, the fresh-food side is not — A transfer fault between the two compartments rather than a refrigeration fault; the damper or the fan that moves air between them is the suspect.
NEAR MISS — the unit is silent and nothing is cold — That is a no-power or start-relay fault, not this one, and it belongs on a different page.

Causes, most likely first on the USBSR line

Choked condenser coil or a stopped condenser fan — Most likely here. This is the cause that punishes a machine in a warm room or a tight cabinet, and it is entirely preventable with a vacuum.
Stalled defrost leaving the evaporator iced — Second on this family. It ranks first because an iced evaporator blocks every cubic foot of air the cabinet depends on, and the parts that cause it are among the cheapest in the machine.
Evaporator fan stopped or obstructed — Third, and less common. The fan behind the freezer rear panel is the part that moves every bit of cold air the fresh-food side receives, and it is the one motor that runs in frost.

Check in this order, and why

Pull the cabinet out and look at the condenser coil — Dust, hair and lint blanket it from underneath. Vacuum it, confirm the condenser fan spins, and give the machine a day before judging the result.
Look at the freezer rear panel for a frost sheet — A solid layer rather than a dusting means defrost has stalled. Emptying the cabinet and leaving it off with the doors open for a day will restore cooling temporarily and confirm it.
Listen at the open freezer for the evaporator fan — Hold the door switch in and listen. Silence where a fan should run separates the two likeliest causes before a single tool comes out.

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. Leave the sealed refrigerant circuit alone: it is licensed work, and a line opened by accident turns a small repair into a replacement.

When to call a technician

The line on the USBSR line is the evaporator panel. In front of it — gasket, vents, coil, load — is yours. Behind it, replacing a defrost heater, a bimetal or a fan motor is a service call, and anything on the refrigerant circuit is licensed work that cannot be done any other way. If the cabinet is above 40 °F (4 °C) and has been for a day, treat the food as the urgent problem and the appliance as the second one.

Frequently Asked Questions

How long will food stay safe while I wait?: A closed refrigerator holds a usable temperature for a few hours and no longer once it has stopped cooling. Move perishables to a cooler with ice and keep the door shut.
The freezer is fine but the fridge is warm. Is that one fault?: Usually yes, and it is an air-transfer fault rather than a cooling fault. The damper or the fan that moves air between the compartments is the first suspect.
