The short answer
A compact Kerong cabinet that runs without cooling is most often placed or loaded in a way that defeats it: too little clearance behind, a warm corner, a door not quite closing. The checks below take minutes and cost nothing. Only when they are clean is a fault inside the cabinet the likely answer. Where these usually stand, the room is the variable that moves most, so start there rather than inside the unit.
What you observe
- The cabinet is warm but you can hear it running — The unit is working and achieving nothing.
- It never switches off — The same fault from the other side, and harder on the compressor than normal cycling.
- NEAR MISS — silent, and nothing is cold — That is a supply or start fault and belongs on the page for a unit that will not start.
Causes, most likely first on a Kerong refrigerator
- Ambient heat and load beyond its capacity — Id: ambient — Room heat and a load put in warm are not a fault, they are a limit: the unit can only move so much heat, and a hot corner or a full shelf of warm bottles uses all of it. First because there is no reserve: a cool room and a warm one are the difference between holding temperature and not. It moves up a place here because of where these units actually live: a warm room is a permanent load rather than an occasional one.
- Condenser coil cannot shed its heat — Id: condenser — Second: the coil is where the heat pulled out of the box is meant to go. Choked with dust, or pressed against a wall with no air moving past it, that heat stays in the room and comes straight back in. Compact cabinets get pushed against a wall or into a cubby, and the specified clearance is exactly what goes missing.
- Sealed system or compressor fault — Id: sealed — Last, and the reason the order matters: when the refrigerant circuit leaks or the compressor stops pumping, everything looks normal and nothing gets cold. It is rare, it is the one fault an owner cannot touch, and it is why the cheap checks come first. Worth knowing early: a sealed-system repair on a compact cabinet usually costs more than replacing it.
Check in this order, and why
- Look at the room, the sun and what went in warm — Placement and load show up here before anything internal does. It comes first because the cause it tests is the one ranked first above.
- Find the condenser and feel whether it is hot and clean — Warm and clean is right; furred is the finding. It follows because the cause it tests is the one ranked second above.
- Feel the cabinet sides and look for oil at the compressor — Only worth doing once everything above is clean. It follows because the cause it tests is the one ranked third above.
What an owner can safely check
- Shut the door on a banknote and try to pull it out, all the way round — Anywhere it comes away freely is a place warm air is getting in.
About 10 min
- Move it somewhere cooler for a day and compare — A few degrees of room temperature change what a small unit can hold.
About 30 min
- Do a full manual defrost with everything out and the doors open — Cooling that returns and then fails again in days names the defrost system.
About 45 min
- STOP HERE if the next step needs a meter on live terminals or the sealed system — That is where owner checks end: refrigerant work is licensed work.
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. Attempt nothing on the sealed system: it is under pressure and the work is licensed. Leave the door switch wired as it is; it cuts the fan for a reason. A tall cabinet is heavy and top-loaded, so get help before pulling one out.
When to call a technician
Call once the room, the clearance, the door and the setting are ruled out, and have the fault named before authorising work: on a compact cabinet repair and replacement sit close enough together that the named fault decides the outcome. Parts come from the seller listing, and the door gasket and the thermostat are the items normally offered.

What this page does not cover
This page covers Kerong refrigerators as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer. Not here: wiring colours, board part numbers and charge figures. It is small cabinets sold online for a room, a bar or an office rather than for a kitchen.
