The AQUA AQR-TZ42N(S) is the satin silver version of the Japanese-market AQR-TZ42N refrigerator. AQUA lists 420 L total storage, including 274 L refrigeration and a 146 L freezer, in a 700 mm-wide cabinet. Check satin-silver finish, no-cooling symptoms, door closure and the correct temperature settings. The matching AQUA manual covers AQR-TZ42N and identifies the interior control panel, door alarm, automatic ice maker and safe household checks. Start by confirming the full model suffix and the symptom rather than assuming a blinking light is an error code. Stop using the appliance for an electrical hazard or suspected refrigerant leak, and seek professional service.
AQUA Satin Silver 420 L TZ Series Refrigerator AQR-TZ42N(S) 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.
What the lights and door alarm mean
The satin-silver N-series version uses the TZ basic Function button. Its manual distinguishes function-indicator blinking from a true malfunction.
The refrigerator can beep when a door is left open. The documented function-indicator light patterns describe operating selections; they are not a verified fault-code glossary. Close all doors fully and consult the control-panel section if a lamp is flashing.
Cooling and ice-maker checks
- No cooling: check the power connection and household outage status. The manual also describes an uncooled showroom/demo mode.
- Weak cooling: review the interior temperature setting, door closure, overloaded storage and air passageways; keep the appliance clear of nearby heat sources.
- Ice not forming: inspect the water tank and follow only the manufacturer-approved cleaning and water-filling guidance.
- Unusual noise or odor: distinguish routine ice drops and fan operation from a persistent symptom using the manual troubleshooting section.
Model-specific demo-mode exit
Only if showroom/demo mode is suspected (panel lights change without input and compartment does not cool): on the internal rear refrigerator panel hold Quick Freeze (クイック冷凍) + Function (機能) for about 6 seconds. Recheck temperature settings. Unplugging will not end demo mode. AQUA manual p. 18. Not a general fault reset.

When to request service
If cooling remains abnormal after manufacturer-approved exterior and control checks, or if the alarm continues with doors correctly closed, contact AQUA service or the selling dealer. Do not disassemble the compressor, electrical assemblies or sealed refrigerant system.
About error-code claims
The controls have indicator lights; the reviewed owner manual does not establish a public, model-specific alphanumeric error-code list. Do not assign generic AQUA or other-brand codes to this model.
