On a machine with a single sealed system, cold is made at one evaporator behind the freezer wall and blown where it is wanted. When defrost stops working, frost builds on that evaporator until air can no longer pass through it — and the first thing you notice is the **refrigerator** going warm while the freezer still looks perfect. People replace thermostats and door seals over this, and the problem is a heater or a sensor in the other compartment. ### What the machine will tell you The refrigeration in this line that carries a display publishes a small set of sensor codes — **E1** and **E2** for the compartment sensors, **E5** for the freezing frost sensor, **E7** for ambient. They narrow the visit usefully. Machines without a display say nothing at all, which is the commoner case. ### What is included Diagnosis including the defrost cycle, the part, the labor, the condenser cleaned while the machine is out, the cabinet panel refitted and aligned, and temperatures checked in both compartments after a full recovery. **Exact cost is confirmed after an on-site diagnostic.** What moves this figure Defrost heater, sensor, thermostat or evaporator fan The freezer side is where a fridge-side problem usually lives Sensor problems report as E1, E2, E5 and E7 on machines that display them Which compartment is actually wrong A refrigerator that has gone warm while the freezer is still frozen solid is nearly always an airflow or defrost problem on the freezer side, not a cooling failure. The evaporator is there, the air is moved from there, and that is where the repair happens. Heater, sensor or fan Three ordinary parts at three ordinary prices, and they are told apart by measurement rather than by symptom — all three produce a machine that slowly stops cooling. A built-in column behind a cabinet panel comes out, and it goes back aligned. That is planned time and it is the part of this figure that is about the installation rather than the problem. Whether the condenser has ever been cleaned Here that matters more than it does anywhere colder. Salt and dust load a condenser fast a few blocks from the water, and a machine working against a blocked one looks exactly like one that is failing.

It is the classic signature of a defrost problem in the freezer, where the cold is actually made. It is one repair and it is on the side that looks healthy. ### Is it worth defrosting it manually first? It will make it cool again for a few days and it will come back, so as a test it is genuinely useful — if unplugging it for twenty-four hours fixes it temporarily, that confirms defrost rather than the sealed system, and that is the cheaper half of this appliance. ### How often should the condenser be cleaned here? Twice a year on this coast, and more if you are close to the water or have pets. It is the single cheapest thing you can do for a refrigerator and it prevents the expensive row on this page. --- **[Read full article: Refrigerator cooling & defrost repair cost](https://bertazzonimiami.support/repair-cost/refrigerator-cooling-and-defrost-repair/)**
