This equipment publishes almost no codes, so what it is doing matters more here than on anything else on this site. - **From $95** diagnostic, credited to the repair - **59** cities and neighborhoods covered - **OEM** parts available on order - **In writing** the price, before anything is opened ## Book a diagnostic visit Your model number and a line about what it is doing is enough to get started. Your details stay private. No spam, ever. Five ordinary causes ## What this usually turns out to be Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours. - 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.

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.

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.

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.

It is worth far more than the built-in display, which reports what it was asked for rather than what it achieved. ### Put a thermometer in each compartment Overnight, in a glass of water.

This is the cheapest outcome and in this city it is a common one. ### Pull the grille and look at the condenser Furred with dust or white with corrosion.

Silence in the freezer is a strong clue. ### 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. How it shows up ## What people describe when they call - “One compartment warm, the other fine” - “Compressor running almost constantly” - “Frost building at the back of the freezer” A shortcut ## Narrow it down before anybody arrives A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears. If there is no code at all The data plate is inside the cabinet, upper left wall or behind the grille. [ All models ](https://esbosch.djwp.xyz/models/) In more detail ## About 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. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about bosch refrigerator not cooling That split is genuinely useful and it usually means air is not moving from one to the other — an evaporator fan or a defrost circuit that has iced over. It is rarely the compressor, which is good news. If the compartment has been above temperature for hours, treat it as today’s problem for food safety. A slow drift with normal contents is worth booking rather than rushing. Very plausible. A refrigerator in a kitchen held at 82 degrees works considerably harder than the same unit at 72, and a marginal condenser will show it first.
