Use this Toshiba SHRM Advance R32 P25 error code guide to capture the fault correctly and see what should be checked before parts are quoted.
What does Toshiba P25 mean?
Toshiba SHRM Advance R32 P25 is listed as compressor inverter PCB fault in SHRM Advance MMY-SUG R32 source row. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
Indoor or outdoor PCB fault recorded by the source table.
Power supply, connector, fuse, EEPROM, or board-input problem.
Water ingress, surge damage, or wiring issue that must be ruled out before board replacement.
What to do now
Use these steps before customer action or a parts quote.
Stop using the unit if P25 returns
If P25 remains displayed or returns during operation, do not attempt an unsourced reset; get the matching source row diagnosed.
No manufacturer reset steps listed for P25
Capture the complete P25 display and model stickers first. The selected source row lists no customer reset procedure; do not treat a generic power-cycle as manufacturer guidance.

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.
| Source detail | What it says |
|---|---|
| Diagnostic note | Stop repeated reset attempts. A qualified technician should verify power, connectors, winding or insulation readings, and the indicated PCB or compressor circuit. |
| Singapore / model note | Official Toshiba SVM-22072-1 row for SHRM Advance MMY-SUG R32 heat-pump and heat-recovery systems. The checked manufacturer page is regional rather than a Singapore product listing, so confirm the full model suffix and locally supplied service manual before diagnosis or parts replacement. |
What to check before repair
Use this split to separate safe evidence capture from the tests a technician should prove before quoting parts.
| You can check | Technician should confirm |
|---|---|
| Before taking any system action on P25, take a clear display photo. | Confirm which PCB or board input P25 points to on the source row. |
| Capture the Toshiba SHRM Advance R32 indoor and outdoor model stickers so the correct family row is used. | Check power supply, fuses, connectors, wiring, and board indicators. |
| The selected source row lists no customer reset procedure. Note whether one room, several rooms, or the whole system is affected. | Rule out water ingress, surge damage, and connected component faults before replacing the board. |
What changes the next step
These clues decide whether the first check is room-side, shared outdoor-side, refrigerant-side, source-table, or model-family confirmation.
| What you see | What it points to |
|---|---|
| Only one indoor unit shows P25. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same P25 fault. | Prioritise the shared outdoor side, power path, and source-listed system branch. |
| The fault remains displayed or returns during operation. | Start with the source-row diagnostic branch before approving parts. |
| The model family is different from the row you found online. | Use the model or series filter first; same-looking codes can still belong to different diagnostic tables. |
| The model belongs to SHRM Advance MMY-SUG R32 source row. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
PCB repair or replacement decision
Toshiba SHRM Advance R32 P25 should not jump straight to board replacement. Confirm power, connectors, wiring, and connected parts before deciding whether PCB repair or replacement is justified.
Power, fuse, connector, and water-ingress checks should happen before board replacement.
Connected motors, sensors, or valves can damage or confuse a PCB diagnosis.
Board availability and system age decide whether replacement is sensible.
