DE in capitals on the display is demonstration mode — lights and controls alive, cooling switched off deliberately, which is how a showroom floor model behaves and how one occasionally arrives in a house. Then look at the load: a cabinet packed to the back wall blocks the vents the cold arrives through, and misses temperature with nothing broken at all. ### What it usually means, by the kind of Monogram appliance Monogram sells one appliance in several forms, and the same behavior points at different things on each of them. A built-in side-by-side and an integrated column are not the same service situation, and a dual-fuel range and an induction range fail in different halves. - **Built-in side-by-side** — Serviced from the front through the grille above the door. The condenser and the air path to it are what to look at first, and they are reachable without moving anything. - **Integrated column** — Establish which cabinet. A refrigerator column and the freezer column beside it are two independent machines, and the healthy one tells you nothing about the other. - **Undercounter and drawer units** — These breathe through a grille a few inches tall at the bottom of the door, and they are often installed somewhere warmer than a kitchen. Ambient is part of the diagnosis rather than an excuse. ### Why the condenser comes first here and not somewhere else A built-in refrigerator does not vent out of the back of the room. It breathes through a grille into the kitchen it is standing in, which means the coil behind that grille takes everything a kitchen produces — and in a house within a few miles of the water, salt as well. It runs hotter, it runs longer, and the first thing most people notice is a power bill rather than a temperature. ### What changes when the cabinet is panel-ready The door is heavy and the hinge was shimmed for its weight on the day the kitchen was fitted. Doors settle. A gasket that no longer meets the cabinet along its whole length lets humid August air in continuously, and the defrost circuit — sized for ordinary use — never catches up. Frost that comes back within days of being cleared is very often this, and the repair is an adjustment rather than a part. Demonstration mode DE on the display. The appliance is doing exactly what it was told and nothing is wrong with it. Unplugging for a minute or two clears most of them. The condenser Salt air, dust and cooking grease on the coil behind the grille until it cannot shed heat. The most common finding in this city and the cheapest to correct. A door that has stopped sealing A heavy custom panel settles over years, the seal stops meeting the cabinet along its top edge, and humid air walks in all day. The defrost circuit Ice on the evaporator that never clears, so air stops moving through it. The cabinet warms up while the compressor runs continuously. A fan or a sensor Cold that is being made and not delivered looks identical from the front to cold that is not being made at all. The sealed system Real, expensive, and quoted far more often than it happens. Everything above is eliminated first and it is reached with gauges, not by elimination alone. Read the display FF means the freezer is warming and the food is what to check first. CC means the temperature is not what it was set to. DE and dE are different things and the case is what tells them apart. Measure both compartments With a thermometer on a middle shelf, not by hand and not off the display. The display and the shelf disagreeing is itself a diagnosis. Look at the grille Above the door on a built-in, at the bottom on an undercounter unit. If you cannot see through it, that is your afternoon. Close a strip of paper in the door At several points around the perimeter. Where it pulls out freely, the seal is not sealing there. Everything works except the cold What it usually means The condenser is the first suspect and it is free to check A dropped door panel produces this too The sealed system is last, not first The two checks that cost nothing Look for a mode before you look for a part.

That usually means cold is being made and not delivered, or the machine cannot shed the heat it is producing. Ice on the evaporator, a stopped fan or a blocked condenser all give exactly this. It is also a good sign for the repair — continuous running means the compressor is alive. ### Someone quoted me a compressor over the phone. Nobody can reach that conclusion without measuring at the appliance. It is the most over-diagnosed repair on a cold appliance in this city. --- **[Read full article: Refrigerator not cooling](https://monogrammiami.support/symptoms/refrigerator-not-cooling/)**
