--- title: "Refrigerator not cooling" description: "Bosch refrigerator not cooling — a refrigerator running warm, cooling unevenly, or holding overnight and drifting by day." url: "https://boschmiami.support/symptoms/refrigerator-not-cooling/" date_modified: "2026-08-18" Appliance type: "Refrigerators, Wine & beverage storage" --- # Bosch refrigerator not cooling ### The fastest diagnosis is the code There is unlikely to be a code, and that is normal — this manufacturer publishes three of them for its entire refrigeration line. What replaces the code is measurement: which compartment, by how much, and since when. ### Without codes, behavior is the diagnosis Which compartment drifted, by how much, over how long, and what changed around it. A refrigerator that failed the week the air conditioning was set back for the season is telling a different story from one that has been drifting since February. Both are worth saying when you book. ### What this climate does A condenser here works against a warm kitchen for most of the year, and near the water salt shortens the coil and the fan motor on top of that. Seasonal cleaning is the single cheapest thing anybody can do to stay off the sealed system page. A condenser that cannot shed heat Dust inland, salt corrosion within a few blocks of the water. In this climate it is the first suspect and often the whole answer. A door seal letting humid air in The paper test settles it in a minute. Humid air condenses inside, frosts the evaporator and shows up as a compartment that will not hold — a cheap cause imitating an expensive one. The evaporator fan If air is not moving over the coil, the freezer stays cold and the refrigerator does not. That split is the clearest single clue on this page. A defrost circuit that never completes Frost builds on the evaporator until air cannot pass. Slow onset over weeks, with the freezer usually still fine. The sealed system The expensive answer and the last one to reach for. A compressor running continuously without the cabinet coming down points here. Put a thermometer in each compartment Overnight, in a glass of water. It is worth far more than the built-in display, which reports what it was asked for rather than what it achieved. Pull the grille and look at the condenser Furred with dust or white with corrosion. This is the cheapest outcome and in this city it is a common one. The paper test on the seals A sheet closed in the door should drag when pulled. Do it every foot around the frame, corners included. Listen for the fan With the door open, press the door switch. You should hear air moving inside. Silence in the freezer is a strong clue. Diagnosed by behavior What it usually means One compartment warm, the other fine Compressor running almost constantly Frost building at the back of the freezer The fastest diagnosis is the code There is unlikely to be a code, and that is normal — this manufacturer publishes three of them for its entire refrigeration line.
