This is the appliance call we take most, and it worries people more than it should. A freezer holding temperature is proof the sealed system is working. Cold is being made. It is simply not arriving where you need it.
Where the cold comes from
On almost every domestic refrigerator there is one evaporator coil and it lives in the freezer. A fan blows air across it and pushes some of that air up a duct into the fresh food compartment. Two things interrupt that without touching the freezer at all: the fan stops, or the duct ices over.
The check that costs nothing
Open the freezer and listen. A fan running is audible. Then open the fridge, hold the door switch in, and feel at the vents at the top of the compartment. Air moving means the fan is fine and you are looking at the damper or the control. No air means the fan or the ice.
What it usually turns out to be
- Evaporator fan motor. The cheapest outcome and a common one.
- An iced-over evaporator. Which means the defrost circuit: heater, thermostat, or the board driving them. Ice builds over a week or two, which is why these arrive gradually rather than overnight.
- The damper between compartments. A flap that has stuck shut. Inexpensive.
- A door seal on the fridge side letting warm air in faster than the duct can deal with.
What to do while you wait
Move anything genuinely perishable to the freezer or to a cooler. Do not turn the refrigerator colder; on most designs that brands the icing worse rather than better. And do not empty it entirely, because a full compartment holds temperature far longer than an empty one.
Is it worth repairing?
Almost always. Every item on that list is a small fraction of a replacement, and none of them involves the sealed system, which is the part that decides whether a refrigerator is finished.
