The short answer
A Coca-Cola CKRF refrigerator that keeps running without getting cold inside is hardly ever a dead compressor. Heat that has nowhere to go comes right back inside. This platform keeps coil, fan and compressor behind one back panel, and that packaging is what moves the diagnostic order around.
The observable signs on this platform
- Continuous running with no drop in temperature — The hum is steady and the unit never cycles off, yet nothing inside comes down to a safe holding temperature.
- The cabinet gets cool, not cold — This version takes the compressor off the table almost on its own.
- It tries to start and gives up — Clicking on a short interval is the protector cutting out, which is a starting-circuit or compressor question.
- NEAR MISS — no hum at all, no cooling — That is a power, control or start-relay fault rather than the cooling loss this page covers, and it is diagnosed the other way round.
Ranked causes for these models
- Condenser coil buried in lint — Top of the list here: the hot side is the bottleneck of a cabinet this small, and it is the part owners never clean.
- No air circulating inside — It ranks here only on the fan-cooled models of this family — where a fan exists it is the part that wears, sitting in cold, damp air for years.
- Door seal no longer sealing — It earns this position by frequency, not by drama: the fault is slow and constant and it never gets better on its own.
The order to work in
- Start at the back, with the coil and its clearance — It needs no tools.
- Check whether air is actually being circulated — On a fan-cooled model this splits the field in half in seconds, which is why it comes before any panel is removed.
- Test the door seal corner to corner — Do it early, because a bad seal looks like everything else on this list.
Safety first, and it is not optional
Safety
Leave the sealed system alone entirely; it needs recovery equipment and a licence, and opening it releases refrigerant that has to be recovered. Coil fins cut and the tubing behind them is hot — gloves and a cooled-down machine keep this simple. Pull the plug before any panel comes off — a capacitor can hold energy after the power is off, and the starting components sit right where your hands go.

When to call a technician
Do not wait if you smell burning or find the breaker tripping: oil outside the tubing means the system is open. Once the diagnosis points at a heater, a terminator or a control board, the testing needs a meter under power.
