The short answer
On a two-door compact the fresh-food section is cooled by spill-over from the freezer plate, so a warm fridge with a cold freezer is an air-path problem rather than a cooling one. Ranked first on this platform: A blocked transfer port between the compartments. The checks below follow that ranking, and the first of them need no tools and no panel removed.
What you observe
- The freezer section is cold and the fridge section below it is not — A split between two compartments served by one plate is an air-path fault, not a cooling one.
- A thick layer of frost on the plate and a cabinet that is not cold — Frost and warmth together on one cabinet is the whole mechanism in one observation.
- The cabinet is steadily too warm rather than varying through the day — A consistent wrong temperature is a control symptom; an inconsistent one usually is not.
- NEAR MISS — the freezer is fine and only the fresh-food side is warm — A split like that points at the air path between the two compartments, not at the cooling itself.
Causes, most likely first on this platform
- A blocked transfer port between the compartments — On a two-door compact the freezer plate cools both boxes, and the fresh-food section gets its cold through a small port between them. It ranks first on this platform because the port between the two compartments is small enough to be closed by one flat package or by a growth of frost, and when it closes the lower box warms while the plate above it carries on working perfectly.
- Frost on a manual-defrost plate insulating it — A compact cabinet has no defrost heater: the evaporator plate is cleared by the owner switching the cabinet off and letting it melt. It ranks second here because the freezer compartment has no heater and no timer: frost accumulates on the plate until somebody empties the box and lets it melt, and on a two-door compact that plate is also what cools the fresh-food section below.
- The temperature control set wrong or drifted — A mechanical control is a bulb, a bellows and a switch, and all three drift with age. Ranked third: worth checking once the causes above have come back clean.
Check in this order, and why
- Look for the opening between the two compartments and check nothing is against it — It explains the exact split the owner is describing. It leads because it tests the top-ranked cause.
- Look at the thickness of the frost on the plate — More than a light fur is enough to explain the complaint, and it needs no tools. Tests the second-ranked cause.
- Turn the control to its coldest setting and listen for the compressor to start — It separates a control fault from a refrigeration fault in one movement. Tests the third-ranked cause.
What an owner can safely check
- Clear the transfer port and keep packages a hand-width away from it — Also check it is not frosted closed, which looks like nothing at all from the front.
About 15 min
- Empty the cabinet, switch it off and let the plate melt completely — Never chip it: the plate is thin aluminium with refrigerant behind it and a puncture ends the cabinet.
Tools: towel, clothAbout 40 min
- STOP at the first panel that needs a tool, and write up what you found — A technician who arrives knowing which checks came back clean spends the visit fixing rather than repeating them.
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.
When to call a technician
A technician is the answer once the airflow, the door and the condenser are all clean and the cabinet still will not hold temperature, because everything left on the list is measured rather than looked at.

This page is written for the MircoChill refrigerator as a class, not for one family or one model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and the one to read first. Deliberately not here: part numbers, wiring colours and disassembly order, which differ by family.
