What We Fix
A refrigerator has one job, and when it stops doing it cleanly your food and your patience pay for it. We handle the full range of faults on built-in, integrated and column refrigeration:
- Fresh-food or freezer compartments running warm while the other stays cold.
- Iced-over evaporators and defrost systems that no longer clear frost.
- Compressors that will not start, cycle constantly, or run hot.
- Evaporator and condenser fan motors that seize, whine or stop.
- Control boards, thermistors and dampers that read or regulate temperature wrong.
- Water in the crispers, pooling under the unit, or freezing at the bottom of the fresh-food side.
- Door gaskets that no longer seal, letting warm, humid air in.
Common Problems and Typical Causes
Most refrigerator complaints trace back to a short list of components. The table below pairs the symptom with what usually causes it, so you have a sense of the diagnosis before we arrive.
| Symptom | Typical Cause | What We Do |
|---|---|---|
| Fresh food warm, freezer cold | Evaporator fan, defrost fault, or one failed sealed system | Test airflow and the fresh-food evaporator; repair the affected system |
| Both compartments warm | Compressor, start components, or a refrigerant charge issue | Verify compressor operation and sealed-system pressures |
| Frost sheeting on the back wall | Defrost heater, thermostat or control | Test the defrost circuit and replace the failed part |
| Constant running, never satisfied | Dirty condenser, door seal, or thermistor | Clean the condenser, check seals and sensor readings |
| Water under the unit | Clogged defrost drain or cracked drain pan | Clear the drain line and replace damaged parts |
Two Independent Sealed Systems
Many Sub-Zero built-ins use two independent sealed systems, one for the fridge and one for the freezer, kept apart so humidity does not migrate between them. It also means a fault in one compartment does not doom the other. Diagnosing these correctly is exactly the kind of work this brand was built around. Our guide on dual refrigeration systems explains it in depth.
Brands We Service
We repair refrigeration across the luxury roster: Sub-Zero, Thermador, Viking, Miele, Liebherr, True Residential, Monogram, Jenn-Air and KitchenAid. Whatever the badge, we source genuine OEM parts by model and serial.

Frequently Asked Questions
Why Is My Sub-Zero Fresh-Food Side Warm but the Freezer Is Cold?
On a dual-refrigeration built-in, the fresh-food and freezer compartments run separate sealed systems. A warm fridge with a cold freezer usually points to the fresh-food evaporator fan, a blocked defrost, or a fault in that one sealed system, not the whole unit.
Can a Built-In Refrigerator Be Repaired in Place?
Most repairs are done in place. We remove the grille and access panels, and only pull the unit from its cabinet opening when a repair needs rear access, protecting the floor and cabinetry as we go.
Is a Warm Refrigerator Worth Repairing?
Usually yes. A failed evaporator fan or defrost part is a modest repair against the cost of replacing a built-in that can run well into five figures. We give you a written estimate so you can compare with real numbers.
