The short answer
A Cafe L refrigerator that runs steadily while the food warms is making cold and not delivering it. On this platform the air path — coil, fan, damper — gives out long before the sealed system does, so the order below starts at the air. The matrix below names one tag carrying wildcard positions, so it stands for a set of trim and finish variants built on one platform; the mechanism is shared across all of them.
What you can observe on these models
- The freezer is still hard-frozen while the fresh-food side is warm — Cold is being made and is not arriving upstairs. On a two-compartment cabinet that points at the damper and the air path, not at the compressor.
- A solid sheet of frost across the freezer rear panel — Normal frost is a light dusting that comes and goes with the defrost cycle. A continuous sheet means the cycle has stopped clearing it.
- The air at the fresh-food vents is barely moving — Put the back of your hand at the vent. No movement at all reads as a stopped fan or a shut damper; weak and cool reads as a coil packed with ice.
- NEAR MISS — the unit is completely silent and nothing is cold — No hum at all is a power, start-relay or control fault, not a cooling fault. That belongs on the no-power page and nothing below will help it.
Causes, most likely first on this family
- A stalled defrost cycle leaving the evaporator iced over — Ranked first on this platform because adaptive defrost degrades rather than fails: the heater, the bimetal or the control stops clearing the coil, ice accumulates over weeks, and the owner notices the warm food long before the frost. It is also the cause the brand-generic page ranks second, and the reason it moves up here is access — on these models the coil is behind one panel and can be confirmed in one step.
- A damper or air-diffuser stuck shut between the compartments — Second. It presents as a warm fresh-food compartment over a perfectly cold freezer, which is the one symptom pattern that rules the compressor out entirely.
- A door seal, alignment or a compartment left ajar — Third. Cheap, common after a move, and worth a minute before any panel comes off.
- A sealed-system or compressor fault — Last. A leak or a failed compressor does produce this symptom, but it produces it after everything above has been ruled out, and it is licensed work when it does.
Check in this order, and why
- Decide which compartment failed first — Freezer cold with a warm fresh-food side points at the damper and the air path; both warm together points at defrost, the condenser or the sealed system. Every later step follows from this one answer, so it is not worth touching anything until you have it.
- Feel for air at the fresh-food vents — This separates a stopped fan from an iced coil without a tool: nothing moving at all is a fan or a closed damper, while weak and barely-cool air is a coil the fan is trying to blow through.
- Listen at the freezer with the door switch held in — The fan stops when the door opens, so the only way to hear whether it runs is to press the switch and listen. It is the cheapest decisive test on the whole page.
Before you open anything
Safety
Disconnect power at the plug or the breaker before any panel comes off; a capacitor can hold a charge after the power is off. Thaw ice, never chip it — the evaporator tubing is soft aluminium and a puncture takes the repair out of owner territory for good. If you pull the cabinet out to reach the condenser, walk it rather than dragging it by a door, and keep the doors shut while it is on the move.

When to call a technician
Everything above that needs no screwdriver is an owner job on these models. The line is crossed the moment the answer depends on measuring something: a defrost heater under load, a thermistor against its curve, or a refrigerant charge. Refrigerant work is licensed work in any case. Stop and call the same day if oil appears anywhere outside the tubing, because oil outside means the system is open and every further hour of running costs more to put right.
