A-stage 90 L two-door refrigerator/freezer (black; registry-listed) RF02A-90BK Error Codes
No manufacturer-confirmed error symbols are currently recorded for this exact model. This does not prove that the appliance cannot display a code or warning.
No verified code list available. Use the matching model manual or manufacturer support for unexplained display messages.
The directory currently provides no verified error-code table for this model. Check the official model manual and symptom advice; do not apply generic codes from another appliance.
The model number RF02A-90BK appears in official Japanese government energy-efficiency product listings under A-stage, describing a 90 L two-door refrigerator/freezer (black (BK) suffix). That listing verifies the model identity and nominal capacity, not the appliance control system, electrical ratings, refrigerant, or error-code applicability. The A-stage web product and manual currently found for RF02A-90WT explicitly name the white WT variant; a manufacturer source explicitly covering this suffix has not been found in this research pass.
What is verified
The exact suffix RF02A-90BK is recorded as a 90 L A-stage refrigerator in the Japanese government product listings. No variant-specific operating instructions or digital error-symbol definitions have been verified.
Safe checks pending a matching manual
If the refrigerator has stopped cooling, keep perishable food at a safe temperature elsewhere, check only the accessible power connection and door closure, and note any abnormal sound, frost or smell. Read the actual rating label before connecting power or attempting an adjustment. Avoid resetting controls using instructions from the WT suffix until A-stage confirms they apply. Never open a powered cabinet, disturb refrigerant piping or chip frost with sharp objects.
Research gap and next step
Obtain a manufacturer-issued product sheet and owner manual explicitly naming RF02A-90BK. Confirm the control-panel type, supply rating, compartment capacities and supported procedures before making this page public. A government-listed model is not automatically a verified match to another color variant’s manual.
