If it is short, the refrigerant went somewhere — and adding more sends the same amount out of the same hole, usually within weeks. ::: ## The signs, and why most of them are indirect There is rarely a puddle and rarely a smell. What you get instead is a machine behaving as though it is trying very hard and achieving very little. - **The compressor runs continuously and the cabinet never reaches temperature.** The single commonest report.- **The freezer manages something and the fresh-food side does not.** With little refrigerant in circulation, what cooling there is stays where it is made.- **Frost in a strange, localized patch** on the evaporator rather than evenly across it — one corner iced and the rest clear.- **The machine has become quieter.** People almost never mention this and it is a genuine sign: a compressor with less to compress does not sound the same.- Occasionally **a faint sweet or chemical smell** near the back of the machine. Most owners never notice one. Notice that every item on that list is also produced by something cheaper — a dirty condenser, a stopped evaporator fan, a defrost circuit that has given up, a door that no longer seals. That overlap is exactly why refrigerant is diagnosed **last**. ## Is it dangerous? Proportionately, no, and it is worth being accurate rather than alarming. A domestic refrigerator holds a very small charge — in most modern machines a hydrocarbon refrigerant in quantities measured in grams. It is flammable, which is why the appliance is built and labeled the way it is, and why you do not want a naked flame behind a machine you suspect. It is not a toxic-cloud event, and it does not make a kitchen unsafe to stand in. What to do is ordinary: ventilate the room, stop using the appliance, and have it looked at before somebody works behind it. ## Why the repair is expensive, and why the shortcuts fail The honest sequence is: recover the remaining refrigerant, pressure-test to find the leak, repair it, **evacuate** the system to pull out moisture and air, and recharge by weight rather than by pressure. The evacuation step is the one that gets skipped, and it is the reason a sealed-system repair sometimes fails within a year. Moisture left in a system freezes at the metering device and blocks it; air left in it will not condense and the machine never performs. That, plus the fact that on this maker a great many of these cabinets are **integrated** and have to come out of an opening cut for them, is why sealed-system work sits in a researched market range of roughly **$600 to $1,500** parts and labor. ## The conversation you should be having Not "is it the sealed system" but three questions: - **What was measured to rule out the cheaper causes?** Compartment temperatures, airflow, defrost, condenser, fans, controls. Ask, and expect an answer.- **What is this cabinet worth to replace, including the kitchen around it?** An integrated column is an appliance job and a cabinetry job. A small freestanding machine is a delivery.- **What else on this machine is the same age?** A sealed-system repair on a cabinet whose fans, seals and boards are all a decade old is a different proposition from one on a five-year-old machine. ::: ## The rule we hold ourselves to We quote this repair last, we show you what was measured to get here, and where a repair approaches the value of the appliance you get told that instead of a quote — including when saying so costs us the work. Refrigerant handling is also regulated. Certification is not a nicety on this job; it is the law, and a shop that is casual about it is being casual about other things too. --- **[Read full article: Refrigerant Leak in a Refrigerator: the Signs, the Real Risk, and the Right Response](https://fisherpaykelmiami.support/blog/refrigerant-leak-symptoms/)**
