Panasonic Commercial Aircon F31 Error Code & Blinking Light
Use this Panasonic commercial F31 guide to confirm the source table meaning, capture the reporting equipment and model, and match the service manual before diagnosis.
What does Panasonic F31 mean?
Panasonic commercial F31 is listed as outdoor-unit EEPROM fault in Commercial / building multi - Japan 2012+ and PACi NX PE4R R32 high-static ducted source rows. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
This page imports only the loaded source meaning; use the matching manual for its diagnostic contents and checks.
The reporting equipment and exact installed model determine which service procedure applies.
A cause should be recorded only after the matching service-manual checks are completed.
What to do now
Use these steps to record evidence and match the installed model to its service manual before diagnosis or a repair quote.
Record F31 and match the service manual
Record F31 and stop there; the source table gives no customer reset procedure. Arrange diagnosis with the matching service manual.
No manufacturer reset steps listed for F31
Capture the complete F31 error code and blinking light and model stickers first. The source table lists the meaning but no customer reset procedure; do not treat a generic power-cycle as manufacturer guidance.

F31 error code and blinking light, a clear display photo and blinking-light video if the unit shows one, Panasonic commercial indoor and outdoor model stickers, the controller, gateway, or unit that reported the code, operating mode and affected area, and any power or setting changes made after the code appeared
Source-specific guidance
These diagnostic-reference notes help match the code to the exact model. Electrical, refrigerant, wiring, resistance, and component checks are technician work, not DIY steps.

| Singapore / model note | Official Panasonic Japan database for office/shop and building-multi air conditioners released from 2012 onward. Panasonic Singapore sells commercial FSV-EX ME2 VRF equipment, but this row is not claimed as an exact Singapore, ME2, or ME2R8 model table. Confirm the installed model and its own manual before diagnosis or parts replacement. |
| Singapore / model note | Official current PE4R R32 high-static ducted row. Apply only to a listed S-60PE4R through S-160PE4RA indoor unit with a matching Panasonic PACi NX outdoor unit; do not treat this as a universal Panasonic interpretation. |

What to check before repair
The source table establishes the code meaning, not a repair procedure. Capture evidence first; model-specific tests belong to the matching service manual.
| You can check | Technician should confirm |
|---|---|
| Photograph the complete F31 error code and blinking light before taking any action. | Confirm F31 exactly and record which controller, gateway, or unit reported it. |
| Capture the Panasonic commercial indoor and outdoor model stickers and identify which controller or unit reported it. | Match the indoor and outdoor model stickers, installed family, and reporting equipment to the source scope. |
| The source table provides no customer reset procedure. Preserve the evidence and use the matching service manual for any system action. | Follow the matching service-manual procedure and keep measured test evidence before naming a failed part. |

What changes the next step
These checks confirm source applicability and evidence without treating the code table as a repair flow.
| What you see | What it points to |
|---|---|
| The complete F31 code and reporting equipment are recorded. | Use the source-table meaning as the starting point; the code alone does not identify a failed part. |
| The installed model and source family are confirmed. | Use only the matching service-manual procedure for diagnosis and any permitted system action. |
| A quote names a part, setting change, or refrigerant work from the code alone. | Ask for the model-specific test result that supports it before approving the work. |
