Panasonic aircon F93 error code
Use this Panasonic F93 error code guide to capture the fault correctly and see what should be checked before parts are quoted.
What does Panasonic F93 mean?
Panasonic F93 is listed as compressor abnormal revolution in Residential Panasonic H/F self-diagnosis 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.
Compressor start, lock, overcurrent, overload, or inverter-drive protection.
Power-module, IPM, voltage, or wiring fault affecting compressor drive.
Compressor mechanical or winding issue after electrical checks are confirmed.
What to do now
Use these steps before customer action or a parts quote.
Stop using the unit if F93 returns
Stop repeated restarts if F93 returns; compressor and inverter faults can become more expensive when forced to run.
No manufacturer reset steps listed for F93
Capture the complete F93 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 | Record the exact H/F code from the remote control, indoor display, or Panasonic Comfort Cloud app, then arrange diagnosis by a qualified Panasonic technician. |
| Singapore / model note | SG model applicability is from Panasonic Singapore X-Premium XU product pages; H/F rows are from Panasonic's official self-diagnosis table. Panasonic notes that some codes may not apply to every model. |
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 F93, take a clear display photo. | Confirm whether F93 is compressor start, overload, lock, or drive protection. |
| Capture the Panasonic indoor and outdoor model stickers so the correct family row is used. | Check supply voltage, inverter output, IPM status, compressor current, and winding readings. |
| The selected source row lists no customer reset procedure. Note whether one room, several rooms, or the whole system is affected. | Review trip history and compressor mechanical signs before quoting replacement. |
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 F93. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same F93 fault. | Prioritise the shared outdoor side, power path, and source-listed system branch. |
| The outdoor unit hums, starts briefly, or trips soon after startup. | Power, inverter, IPM, compressor current, and winding checks decide the repair path. |
| 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 Residential Panasonic H/F self-diagnosis source row. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
Compressor drive or replacement decision
Panasonic F93 can still be a repair if power, inverter, or module checks find the cause. Compressor replacement should be weighed against age, warranty, and the rest of the system condition.
Inverter or IPM faults are not the same as confirmed compressor mechanical failure.
Compressor winding and current readings should be measured before replacement is discussed.
Older systems need a repair-versus-replace check if compressor-side parts are expensive.
