A refrigerator that has stopped cooling is the most urgent appliance failure in any kitchen, because the food inside is on a clock. The cause is almost always one of a handful of components: a failed evaporator or condenser fan, a defrost fault icing the evaporator, a refrigerant leak, or a starved condenser coil.
On premium built-ins the picture is a little different from a standard refrigerator, and the brand matters. Below are notes on how the most common brands in Wayne-Radnor kitchens present a no-cooling failure, along with a quick guide to what we check first.
Notes by Brand
The same symptom can point to different components depending on the brand. Here is how it tends to present across the appliances we service.
| Brand | How It Presents |
|---|---|
| Sub-Zero | Because Sub-Zero runs two independent sealed systems, a warm fresh-food side with a cold freezer isolates the fault to the fresh-food circuit, usually an evaporator fan or a leak. |
| Bosch / Thermador | Counter-depth Bosch and Thermador units most often lose cooling to a failed evaporator fan or a defrost fault, sometimes flagged by a sensor code. |
| Miele / Liebherr | MasterCool and Monolith columns typically show a temperature alarm or sensor code (such as Liebherr E1 or E2) when cooling drops. |
| Viking / True | These forced-air units usually lose cooling to a condenser or evaporator fan or a dirty condenser rather than electronics. |
Quick Diagnostic Guide
| Code / Symptom | What It Means | What We Do |
|---|---|---|
Warm fridge, cold freezer | Fresh-food evaporator fan or refrigerant leak | Isolate and repair the fresh-food circuit |
Both compartments warm | Starved condenser or compressor start fault | Service the condenser, test the start components |
Icing on the back wall | Defrost heater or control failed | Replace the defrost part, clear the drain |
Runs but stays warm | Low refrigerant charge or sealed-system leak | Locate and seal the leak, recharge to spec |
Move Perishables Early
If the interior is above 40 degrees, move perishable food to a cooler or another refrigerator. Food held above that temperature for more than two hours should not be kept, and prompt action protects your family while we restore cooling.
