Not cooling / temperature too high COMPRESSOR Unit runs but wine not reaching set temperature | $200–$420 + compressor or refrigerant | Compressor failure, refrigerant leak (requires EPA-certified technician), condenser coil blockage (often just cleaning), thermistor. Ambient temperature assessment included. |
Peltier element failure THERMOELECTRIC No cooling at all, unit warm despite running | $150–$300 + Peltier module | Peltier (TEC) module replacement. We assess repair vs. replace economics on smaller units before ordering. Ambient temperature check included — sometimes the unit just needs a cooler location. |
Fan not working Unit silent, no airflow, condensation issues | $150–$280 + fan motor | Evaporator fan or condenser fan motor replacement. Fan failure causes rapid temperature rise on both compressor and thermoelectric units. |
Temperature inaccurate / fluctuating Can’t hold set temperature, wide swings | $160–$320 + thermistor or thermostat | Temperature sensor (thermistor), thermostat replacement. Diagnosis confirms sensor vs. refrigeration issue. |
Excessive noise / vibration Loud compressor, rattling, vibration through floor | $160–$340 + compressor mounts or fan | Compressor mounting dampers, loose internal components, fan blade contact. Vibration is a premium concern for wine storage — we address carefully. |
Condensation / moisture inside Water pooling inside, fogging door, wet bottles | $150–$300 + gasket or drain if needed | Door gasket replacement (common in LA coastal areas where humidity varies), drain line clearing, thermostat recalibration. LA coastal fog conditions can affect gasket wear. |
Display / controls not working Display dead, buttons unresponsive, error codes | $160–$320 + control board | Control board, display panel, touchpad. Diagnosis confirms board vs. wiring before ordering. |
Door not sealing / hinge failure Door gaps, warm air entering, door misaligned | $120–$240 + gasket or hinge | Door gasket replacement, hinge adjustment or replacement. Gaskets in LA dry climate can harden and crack faster than manufacturer estimates. |
Compressor replacement COMPRESSOR Compressor confirmed failed | $280–$440 + compressor (expensive) | Full compressor replacement with refrigerant recharge. EPA-certified technician required for refrigerant handling. We assess repair vs. replace economics before proceeding. |
Sub-Zero / Liebherr / EuroCave LUXURY All failure types | $280–$560+ + OEM parts (premium pricing) | Proprietary compressor systems, dual-zone precision electronics, European-sourced OEM components. Sub-Zero wine units are common in Brentwood and Beverly Hills kitchens. |
Diagnostic fee Service call + full diagnosis incl. ambient temp assessment | $89 Applied to repair | Applied to labor total when you approve. Includes assessment of unit type, ambient conditions, and repair vs. replace economics for thermoelectric units. |
