RF27T5201SR/AA: Immediately after plug-in or an outage, all icons flashing is the normal self-diagnostic rather than a multi-code fault. Wait for the self-check to finish without pressing random keys; investigate only if a specific code remains afterward. First preserve the exact display, timing and operating state: a similar-looking code in another appliance category can mean something else. Protect perishable food and keep doors closed unless the official step specifically requires defrosting. Never open electrical, fan, compressor or sealed-system covers. After the documented check, use the result to separate a temporary condition from a fault that needs authorised service.
Models covered
Safety first
- Protect perishable food and keep doors closed unless the official step specifically requires defrosting. Never open electrical, fan, compressor or sealed-system covers.
What the symptom may indicate
Checks in the right order
- Record the evidence
Photograph or write down “all icons flash after power is restored” before resetting anything.
- Make the appliance safe
Protect perishable food and keep doors closed unless the official step specifically requires defrosting. Never open electrical, fan, compressor or sealed-system covers.
- Apply the official user check
Wait for the self-check to finish without pressing random keys; investigate only if a specific code remains afterward.
- Decide after one test
If the exact symptom clears, monitor one normal use. If it returns, preserve the code and contact the manufacturer instead of guessing a part.
Stop and get qualified help when
- Arrange service for a returning code, rising food temperature, a hot plug, burning smell, damaged cable, persistent fan impact or water near electrical parts.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
