Common Sub-Zero Problems We Fix
Cooling & Humidity
Temperature drift in open-plan kitchens, moisture on shelves, or frost on the back wall — we restore stable cold-hold and proper humidity.
- Symptoms: warm fridge, wet shelves, frost/ice on evaporator cover.
- Likely causes: door seals/hinges, damper or fan faults, clogged condenser, sensor drift.
- What we do: FF/FZ airflow tests, gasket mapping, condenser clean & amp-draw, calibration to spec.
Sealed-System Wear
Frosting, partial cooling, or noisy starts often indicate sealed-system issues. We isolate the root cause and verify performance after repair.
- Symptoms: ice on evap corner, constant running, hot compressor.
- Likely causes: evap leak, weak compressor, restricted drier/cap tube.
- What we do: leak trace, drier/valves, evacuate & charge-by-weight, cold-hold validation.
Electronics & UI
Random beeps, error codes, dim lighting, or resets after cleaning — we diagnose boards, sensors, and wiring to restore reliable control.
- Symptoms: flashing display, can’t hold set-point, intermittent restarts.
- Likely causes: relay board, PSU, thermistors, harness fatigue.
- What we do: board tests, sensor curves vs spec, continuity checks, firmware reset where supported.
Ice Maker & Water System
Low production, hollow cubes, or leaks near the kick panel. We correct water supply, valves, heaters, and harvest cycles.
- Symptoms: no ice, tiny/hollow cubes, puddles under unit.
- Likely causes: inlet valve, fill-tube freeze, filter restriction, supply pressure.
- What we do: pressure/flow test, valve & inlet checks, heater/harvest test, leak trace.
