What We Fix
We repair the full range of refrigeration failures on premium built-in, integrated and column units. Because a Sub-Zero refrigerator is engineered differently from a mass-market fridge, we approach it as a system: compressor, condenser, evaporator, defrost circuit, controls and door seals all working together to hold a precise temperature.
- Fresh-food or freezer side not cooling, or cooling too much
- Sealed-system faults, including refrigerant loss requiring appropriately qualified handling
- Failed evaporator or condenser fan motors
- Defrost heater, thermostat or control faults causing frost or drain leaks
- Compressor and start-component failures
- Magnetic door gaskets, hinges and dual-drawer alignment
- Water dispensers, filters and internal ice systems
- Control-board and user-interface faults
Common Problems in South Forsyth Kitchens
The call we hear most often across the valley is a built-in where the freezer is still cold but the refrigerator has crept up into the 50s. On a unit with two independent sealed systems that points squarely at the fresh-food side rather than the whole appliance, and the fix is usually far smaller than homeowners fear. We also see condensers packed with dust in homes with pets, defrost drains that freeze and drip onto hardwood floors, and door gaskets that have lost their seal after years of daily use.
Typical Causes
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Fridge warm, freezer cold | Fresh-food sealed system, evaporator fan or defrost fault | Isolate the affected system and test airflow before quoting |
| Whole unit warm | Condenser blocked, compressor or start component | Clean and test the sealed system, verify compressor draw |
| Water under the unit | Frozen or clogged defrost drain | Clear the drain and confirm the defrost cycle |
| Frost inside the freezer | Defrost heater or thermostat | Test the defrost circuit and replace the failed part |
| Running constantly | Door seal, dirty condenser or control | Check seals and airflow, verify the control logic |
Two Independent Sealed Systems
Many built-in Sub-Zero refrigerators run separate sealed systems for the fresh-food and freezer compartments. That is why one side can fail while the other stays perfect, and why an accurate diagnosis matters before any refrigerant work.
