A built-in refrigerator is the heart of a high-end kitchen, and when it drifts warm or ices over it puts thousands of dollars of food and a very expensive appliance at risk. Our technicians service Sub-Zero built-in, integrated, and PRO refrigeration along with other luxury brands, working through the sealed system, defrost circuit, and controls in a set order so the real fault is found the first time.
What We Fix
- Sealed-system diagnosis (compressor, evaporator, condenser, refrigerant charge)
- Dual-zone and dual-compressor temperature faults
- Defrost system repair (heater, thermostat, drain, control board)
- Door gaskets, hinges, and cabinet-flush alignment on built-in units
- Evaporator and condenser fan motor replacement
- Water and ice dispenser lines, valves, and filters
- Control board, thermistor, and user-interface faults
Common Problems We See
- Fresh-food section warm while the freezer stays cold
- Unit running constantly and never cycling off
- Frost or ice building up on the back wall or in the drawers
- Water pooling under the crispers or on the floor
- Loud vibration or clicking from the compressor area
- Digital display reading an alarm or flashing temperature
Typical Causes
Warm compartments usually trace back to a blocked defrost circuit, a failed evaporator fan, a refrigerant leak in the sealed system, or a control board that has stopped switching the compressor correctly. Rather than swapping parts on a guess, we confirm the airflow, defrost cycle, and system pressures before quoting the repair.
We confirm the actual fault with direct testing before quoting. That avoids the common trap of replacing an expensive board when the real problem is a fan, a sensor, or an airflow blockage.
Symptom and Fault Guide
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Warm fresh-food, cold freezer | Failed evaporator fan or blocked defrost | Test fan motor and defrost heater, clear airflow |
| Constant running | Dirty condenser or low refrigerant charge | Clean condenser, check sealed-system pressures |
| Ice on rear wall | Defrost heater or bimetal thermostat open | Replace defrost component, verify drain is clear |
| Water under drawers | Clogged or frozen defrost drain | Flush drain line, install drain heater if fitted |
