The short answer
A cabinet that runs without getting cold: on an IceBox refrigerator that is usually heat with nowhere to go, not a dead compressor. The next thing to rule out is a stalled defrost cycle. The top of that list is owner work; only the last cause needs a technician.
What you are looking at
- The compressor never switches off — It runs without ever satisfying the control.
- 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.
- NEAR MISS -- the freezer is cold and only the fresh side is warm — That points at the damper or the air path between compartments, a narrower fault than this 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 IceBox cabinet squeezed into an under-counter space, it is the cause an owner most often creates by accident, and it needs no tools to rule out.
- 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 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. Placed here: warm air leaking in explains a running compressor and a warm box at once.
- 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.
- Look for a frost sheet where the cold is made — A solid sheet rather than a light dusting confirms it, and separates this cause from the fan.
- 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.
Tools: thermometerAbout 10 min
- 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
Call once the condenser, the seal, the set point and a full defrost are all ruled out.

What this page does not cover
This page covers the IceBox 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.
