Then listen: a fan you can hear when the door is closed and not when it is open is the evaporator fan doing its job, and silence where that sound used to be is one of the most useful things you can tell us. ### One evaporator, two compartments These cabinets make cold in one place and share it. That single design fact explains the most common complaint on this page: when the sharing stops — a fan, a damper, a coil buried in ice — the freezer keeps its own cold and the refrigerator loses everything. It looks alarming and it is usually one of the cheaper repairs in the catalog. ### What our climate adds Condenser coils here load with dust that is damp, so it mats instead of blowing off. Every door opening in August pushes humid air into the cabinet, which becomes frost, which the defrost cycle then has to remove. Neither is exotic, and both are reasons a cabinet that would coast elsewhere asks for attention here. The evaporator fan Cold is made in the freezer and blown into the fresh food side. No fan, no delivery — and the freezer stays perfect while the refrigerator goes warm. Defrost, and a coil iced solid Heater, thermostat or sensor. The coil ices over, airflow stops, and you get exactly the same warm-fridge-cold-freezer picture as a dead fan. A damper stuck shut The flap that meters cold air into the fresh food side. Cheap, mechanical, and capable of producing a very expensive-looking symptom. A condenser that cannot shed heat Behind the grille, matted with dust that is damp here rather than dry. When both compartments are drifting, this is the first thing worth looking at. The sealed system or the compressor The expensive answer and the least likely one. A compressor clicking and humming every few minutes with nothing getting cold is what points here. Establish which compartment is wrong Thermometer in a glass of water, four hours, both sides. It sounds fussy and it is the difference between an airflow diagnosis and a sealed-system one. Pull the grille and look at the condenser No tools needed on most of these. Matted grey dust across the coil is a real cause here, and cleaning it is the cheapest outcome on the page. Listen for the fan, and check the vents Air has to get from the freezer to the fresh food side. A compartment packed solid against the back wall blocks that, and it costs nothing to move things and wait a day. Then book the visit Tell us which side is warm, whether the freezer is still holding, and whether there was a power outage in the last week. Those three answers do most of the narrowing. And the freezer is still cold What it usually means Fresh food side warm, freezer normal Both sides warm and the compressor running It got worse over a week rather than overnight The fastest diagnosis is the code Note which compartment is wrong, and put a thermometer in a glass of water in the fresh food section rather than judging by hand.

Neither is exotic, and both are reasons a cabinet that would coast elsewhere asks for attention here. ### The freezer is fine. Is that good news? Usually yes, and it is why we ask first. A cold freezer proves the sealed system is making cold, so what is left is getting that cold into the fresh food side: a fan, a damper, or a defrost problem that has iced the coil. Those are all far less expensive than the answer people fear. ### How cold should it actually be? Around 37°F in the fresh food section and 0°F in the freezer, measured in a glass of water rather than by air. Air temperature swings every time the door opens and tells you almost nothing. ### It stopped cooling after the power came back on. That timing is worth telling us. It may be nothing more than the cabinet needing hours to pull everything back down, or it may be a control that came up confused. A full breaker cycle of five minutes clears the second one often enough to be worth trying. --- **[Read full article: Refrigerator not cooling](https://kitchenaidmiami.support/symptoms/refrigerator-not-cooling/)**
