The short answer
On a Genuine Comfort refrigerator, a cabinet that runs and stays warm is usually an airflow fault rather than a dead compressor: the evaporator ices over, air stops moving, and the unit runs continuously without ever reaching temperature. Most of the checks below need no tools and no panel removed. A genuine sealed-system failure is the least likely cause on this cabinet and the only one that is not an owner job.
What you actually observe
- Frost has built into a sheet on the freezer rear wall — A sheet rather than the usual light dusting is the classic airflow signature.
- The cabinet is warm but the unit is plainly running — You can hear the compressor; the air inside is not cold.
- NEAR MISS: the unit is silent and nothing is cold at all — That is a no-power or start-relay fault and belongs on the page for a unit that will not start.
The causes, most likely first on this brand
- A failed or iced evaporator fan — Without that fan nothing pushes cold air out of the freezer into the fresh-food side, so one compartment freezes while the other warms. Ranked first on a Genuine Comfort refrigerator: the motors and bearings are specified to a shorter service life, which is what puts this above the rest.
- A door that is not sealing — A gasket that has lost its set, or a door held open by a shelf or a rocking cabinet, lets warm room air in faster than the unit can remove it. Ranked second on a Genuine Comfort refrigerator: the gasket and door hardware are exactly where a value build saves money, so they are the first thing to check.
- A stalled defrost cycle icing the evaporator — Frost builds into a solid sheet across the evaporator until air can no longer pass through it, so the cabinet warms while the compressor runs on. Ranked third on a Genuine Comfort refrigerator: this is a cabinet built to a price, so the parts where the tolerance went are the parts that fail, and they are cheap parts.
Check in this order, and why this order
- Open the freezer and listen for the fan, then press the door switch — The switch cuts the fan, so a noise that starts and stops with the door tells you it is running at all.
- Close the door on a note or a strip of paper and pull it out — If it slides out freely anywhere round the door, the seal is not making contact there.
- Look at the freezer rear panel for a sheet of frost — A solid white sheet rather than a light dusting confirms this cause before any tool comes out.
What an owner can safely check
- Hold the freezer door switch in and listen for the fan to spin up — Silence with the switch held is a fan fault; a rattle or a scrape is a blade catching ice.
About 5 min
- Wipe the gasket clean, then test the seal at several points round each door — Warm water softens a gasket that has taken a set and often restores contact on its own.
Tools: clothAbout 15 min
- STOP HERE if the checks above are clean — the next step needs gauges on a sealed system — Refrigerant work is licensed work and the tools for it are not owner tools.
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, and both fans start without warning. Leave the door switch wired as it is: it cuts power to the evaporator fan for a reason. A refrigerator holds food safely at forty degrees Fahrenheit or below, so move anything perishable to a cooler with ice while you work rather than trusting a cabinet you already know is warm.
When to call a technician
Call once the ice is gone, the coil is clean, the seals make contact and the cabinet still will not hold temperature — at that point what remains is a fan behind a sealed panel, a control board or the sealed system itself. Call immediately if you see oil at the compressor or smell anything burning: oil outside the tubing means the system is open, and every hour it runs after that costs more to put right.

What this page does not cover
This page covers the Genuine Comfort refrigerator as a class, not one family or model line. Part numbers, wiring colours, torque figures and panel fixings differ from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, that page is the more specific answer and should be read first.
