The A-stage R-90WH is a Japan-market two-door refrigerator/freezer listed with 90 L of storage. A-stage identifies the R-90WH as the white member of its 90 L range, with 64 L in the refrigerator and 26 L in the freezer. The published specifications list direct cooling, R600a refrigerant, a 495 × 520 × 845 mm cabinet, 27 kg weight, AC 100 V at 50/60 Hz and a 30 kg top-panel load limit. Start with non-invasive observations: check that the power supply is safe, the doors close fully and stored food is not blocking usable space. If the cord is damaged, there is smoke, a burning smell, or water reaches electrical parts, stop using the appliance and seek qualified service. A cooling problem is not, by itself, an electronic error code.

Cooling problems and safe checks
Refrigerator takes too long to cool
The manufacturer asks owners of this exact model family to check the setting against the matching page-10 temperature-dial guidance, avoid overpacking, keep the rear compressor area unblocked, limit unnecessary door opening, and avoid direct sunlight or heat-producing equipment. A-stage also advises a room temperature no higher than 35 °C for this troubleshooting scenario. If newly installed or recently powered, allow the cooling process to stabilize in line with the manual.
Food is becoming too cold
Check the temperature dial against the Japanese manual instead of assuming that a compressor or sensor has failed. Observe whether the issue changes after an appropriate dial adjustment.
No power or interior light
Inspect the external wall connection if it is safe and dry. Do not dismantle the plug, cord, controls or rear compartment. If the refrigerator still fails to operate, record the symptom and contact the manufacturer or retailer.
Frost, noises and cabinet warmth
A-stage explains that frost in a direct-cooling refrigerator can result from humid air entering the cabinet. It also describes some flowing-liquid sounds as normal refrigerant movement and notes that exterior panels can feel warm during heat release. Persistent failure to cool, unusual electrical smells or visible damage must not be dismissed as normal.
For frost near the freezer, first consult the R-90WH owner manual and follow its approved defrost instructions. Do not use knives, screwdrivers, sharp scrapers, or heat appliances to force ice away from the cooling surfaces.

Error-code evidence and service
The accessible A-stage product page and model-family troubleshooting FAQ describe mechanical temperature adjustment and symptoms, but do not establish a model-specific alphanumeric refrigerator error-code mapping. Do not apply codes from other brands or from A-stage washing machines to this refrigerator. Stop repeated attempts and request professional help when normal cooling does not return after accessible checks.
