--- title: "Freezer not freezing" description: "Bertazzoni freezer not freezing — ice cream that has gone soft, frost building on the back wall, or a column that runs constantly and still will not hold." url: "https://bertazzonimiami.support/symptoms/freezer-not-freezing/" date_modified: "2026-08-27" Appliance type: "Freezer columns, Refrigerators" --- # Bertazzoni freezer not freezing ### The fastest diagnosis is what you can see Leave a thermometer inside overnight rather than trusting the display, and look at where the frost is. Frost on food is normal; frost on the back wall, round the fan, or as a sheet at the base means the defrost cycle is not finishing — and where the ice is tells us which part of that circuit gave up. ### Frost is a diagnosis, not a nuisance Frost on packages is condensation from opening the door and is normal. Frost on the back wall, around the fan, or as a growing sheet at the base is the defrost cycle failing to complete, and it is the most useful thing you can look at before calling. Where the ice is concentrated says which part of the circuit stopped. ### Columns, and what that means for the visit Every freezer here is built into cabinetry behind a custom front. The diagnosis is the same as any freezer; the access is not. Panels come off before anything is measured and go back on aligned afterwards, which is real time on the appointment and worth knowing about in advance rather than at the door. Defrost that is not completing Heater, thermostat or control. Ice builds until air cannot get past the evaporator, and then nothing holds temperature however hard the compressor works. A door not sealing On a column, a heavy panel on tired hinges. Humid Miami air coming in continuously is both a frost cause and a temperature cause. Condenser dust Routine here rather than exceptional, and it makes a machine run constantly while losing ground. The evaporator fan Cold made and not moved. Often audible as a change before it is visible as a temperature. The sealed system Real and last, after everything above has been measured out. On a built-in column it is usually worth repairing; that conversation happens before the work. Thermometer overnight The display is a set point and an estimate, not a measurement. Where is the frost Food, back wall, fan, or base. Each points somewhere different. The paper test on the seal All the way round, including the top edge, which is where a dropped door fails first. Listen for the fan With the door switch held in. Air moving, or not. Frost tells you where to look What it usually means Soft ice cream with the display reading correctly Frost on the back wall or round the fan Running constantly without holding The fastest diagnosis is what you can see Leave a thermometer inside overnight rather than trusting the display, and look at where the frost is.

The defrost cycle is not finishing — heater, thermostat or control. Worth catching early, because ice eventually reaches the fan and then you have a noise problem and a damaged fan on top of the original one. The other cause is simpler and free: a door not quite closing. ### It runs all the time. A column freezer in a Miami kitchen works hard, and running a lot is not the same as running badly. What matters is whether it holds. Constant running at the right temperature is fine; constant running at the wrong one is a condenser, a seal, or a defrost cycle that is not completing. ### Why is there no chest freezer on this site? Because this maker does not build one for this market — every freezer in the line is a built-in column in one of three widths. If you have a chest or a freestanding upright with this badge it is either much older or another maker's, and it is worth saying when you book. --- **[Read full article: Freezer not freezing](https://bertazzonimiami.support/symptoms/freezer-not-freezing/)**
