The short answer
Start here -- on an iio refrigerator, a cabinet that runs without getting cold points first at heat with nowhere to go, not at a dead compressor. Second, and worth checking in the same hour, is a door that is not sealing. Work the order below -- cheap causes first, the one that is not an owner fix last.
What you are looking at
- Food spoils earlier than it should — Milk and leftovers turn early with the dial untouched.
- A thermometer inside disagrees with the panel — A refrigerator holds food safely at forty degrees Fahrenheit or below.
- The cabinet is warm but the unit is clearly running — You can hear the compressor; the air inside is not cold.
- NEAR MISS -- the unit is silent and nothing is cold — That is a no-power or start-relay fault, and it belongs on the will-not-start page.
Causes, most likely first on this kind of unit
- The condenser cannot reject its heat — Heat taken out of the cabinet has to leave through the condenser. Ranked first on an iio compact cabinet on a simple dial control: it is the cause an owner most often creates by accident, and it needs no tools to rule out.
- The door is not sealing — A gasket that has taken a set, a dropped hinge, or a shelf holding the door off its face lets warm humid air in continuously. This rank, because warm air leaking in explains a running compressor and a warm box at once.
- The evaporator is frosted over — Cold reaches the cabinet as air moving across the evaporator. This rank, because frost that has closed the air path gives exactly this symptom with everything else healthy.
- The sealed system or the compressor — A refrigerant leak, a blocked capillary or a compressor that will not pump leaves a cabinet that hums and stays warm. It comes last because it is the least common cause and the most expensive, which is why it is checked last.
Check in this order, and why
- Feel the condenser and the air around it — A coil that is hot with no breathing room answers the question before you touch anything else.
- Paper-test the gasket all the way round — Shut the door on a sheet of paper and pull; anywhere it slides out freely is not sealing.
- Only after the checks above are clean — Oil at the compressor, or a coil that never warms at all, moves this to the front -- and it is a service call.
What an owner can safely check
- Clear the condenser and give the unit room — Vacuum the coil and grille, then pull the cabinet out far enough for hot air to escape.
Tools: vacuum, soft brushAbout 20 min
- Paper-test the door seal all the way round — Check top, both sides and bottom, and clear any shelf holding the door off its face.
About 10 min
- Stand a thermometer in a glass of water inside — Read it hours later rather than trusting the panel; it separates a cooling fault from a control fault.

- STOP HERE -- the next step needs a meter on live terminals — Windings, start devices and sealed-system pressures are technician work.
Before you open anything
Safety
Power off at the plug or the breaker before any panel comes off.
When to call a technician
The line is simple: anything you can reach without a panel is yours, anything behind a panel or on the sealed system is a technician's.

What this page does not cover
This page covers the iio refrigerator as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer -- go there first if your model is named. Deliberately not here: wiring colours, defrost-board part numbers, compressor start devices and the panel-removal sequence, all of which differ by family.
