In practice, the overwhelming majority of cooling complaints on these machines are airflow and defrost: an evaporator fan that has stopped, a damper that has stuck, or a defrost cycle that no longer completes and has iced the evaporator over. Those are ordinary parts and ordinary visits. The sealed system is a separate page for a reason — it is a different job at a different price, and it is not where a diagnosis starts. ### What we check, in the order we check it - Actual temperatures in both compartments, measured rather than read off a display - Condenser coils and grille — dust is a genuine cause here, not a lecture - Door seals and door closing, which decide how hard the machine has to work - The evaporator fan and the damper: is cold being made, or is it not being moved? - The defrost heater, thermostat and control as three separate things ### Freestanding, built-in and column Seventeen of these thirty are freestanding and come out into the room, which makes for the shortest visits. Eleven are built-in with the machinery behind a grille at the top. Five are columns wearing your own cabinet fronts, where panels come off before anything is measured. It is worth telling us which you have when you book, because it decides the length of the appointment more than the part does. ### What the repair costs Cooling and defrost work starts at $185. If the answer is a condenser clean and a door adjustment, that is what you are charged for and we will say so. What this involves Airflow separated from cooling before any sealed-system talk The defrost circuit tested as heater, thermostat and control Condenser and seals checked first, because both are free Measure both compartments properly What the display claims and what a thermometer says overnight are different things, and the gap between them is the diagnosis. A freezer at zero with a fridge at fifty is a completely different problem from both compartments drifting together. The free causes Condenser coils and the grille in front of them thick with dust — routine in this city rather than exceptional. A door seal that has stopped sealing. A door that does not close on its own. All three produce a machine that runs and runs. Separate cold from airflow On most of these one evaporator serves both compartments, with a fan and a damper moving the air. A stopped fan, a stuck damper or an evaporator quietly building ice all give you a cold freezer and a warm fridge — and none of them is the compressor. Test the defrost circuit Heater, thermostat and control, as three parts. A defrost that never completes builds ice on the evaporator until the air cannot get through, and the symptom arrives weeks later as a temperature complaint with no obvious cause.

That usually means the cold is being made and is not getting where it should — which is a much better position than it sounds. The fan that moves air between compartments, the damper that meters it, or an evaporator icing up are the three candidates, and all three are ordinary repairs. It very rarely means the sealed system. ### It runs constantly. Is that bad? Not by itself. A refrigerator in a Miami August works hard, and a built-in one in a warm kitchen works harder. What is worth a call is a machine that runs constantly and is not holding temperature, or one that has started running constantly after years of cycling normally. Dust on the condenser is the first suspect and it costs nothing to rule out. ### There is frost on the back wall of the freezer. The defrost cycle is not finishing. That is a heater, a thermostat or a control, and it is worth catching early because the ice eventually reaches the fan — at which point you have a noise complaint on top of a temperature one, and a fan that has been chewing ice for a month. ### How long should a fridge take to recover after being opened a lot? On a busy day a healthy machine will sit a few degrees above its set point and pull back within an hour or two of being left alone. What is not normal is a machine that never gets back, or one that recovers only overnight. If you are unsure, a cheap thermometer left inside for twenty-four hours tells us more than any description can. --- **[Read full article: Refrigerator cooling & defrost repair](https://bertazzonimiami.support/services/refrigerator-cooling-and-defrost-repair/)**
