Midea Aircon PC 01 Error Code
Capture the Midea PC 01 fault correctly, then see what should be checked before parts are quoted.
What does Midea PC 01 mean?
Midea PC 01 is listed as outdoor unit voltage protection, low or high voltage in Inverter Split rows such as Midea wall-mounted inverter error-code quick troubleshooting table. This meaning comes from the manufacturer's own diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
Voltage, current, fuse, module, or power-supply protection has been triggered.
Loose connector, damaged harness, or outdoor electrical component fault.
PCB or inverter-module issue after power and load checks are confirmed.
What to do now
Use these steps before customer action or a parts quote.
Stop using the unit if PC 01 returns
Stop repeated restarts if PC 01 returns, trips power, smells burnt, or the outdoor unit runs unusually hot.
No manufacturer reset steps listed for PC 01
Capture the complete PC 01 display and model stickers first. The manufacturer lists no customer reset procedure; do not treat a generic power-cycle as manufacturer guidance.

Guidance for your model
Notes that match the code to your exact model. Electrical, refrigerant, wiring, resistance and component checks are for a technician.
| Detail | What it says |
|---|---|
| Diagnostic note | Use the source quick-check path: Check the power supply, inverter module, outdoor main PCB, and reactor. |
| Singapore / model note | For Singapore homes, start by checking the isolator and recent breaker trips. Leave PCB and live-voltage checks to a licensed technician. |

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 PC 01, take a clear display photo. | Confirm whether PC 01 is voltage, current, module, fuse, or protection related. |
| Capture the Midea indoor and outdoor model stickers so the correct family row is used. | Check incoming voltage, connectors, inverter module, and current draw under load. |
| The manufacturer lists no customer reset procedure for this code. Note whether one room, several rooms, or the whole system is affected. | Confirm downstream loads before replacing electrical boards or modules. |

What changes the next step
These clues decide whether the first check is room-side, shared outdoor-side, refrigerant-side, listed-meaning, or model-family confirmation.
| What you see | What it points to |
|---|---|
| Only one indoor unit shows PC 01. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same PC 01 fault. | Prioritise the shared outdoor side, power path, and source-listed system branch. |
| The fault remains displayed or returns during operation. | Start with the checks the manufacturer lists for this code 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 Inverter Split rows such as Midea wall-mounted inverter error-code quick troubleshooting table. | This meaning comes from the manufacturer's own diagnostic material. Match the code to your model's listing before parts are quoted. |

Electrical module or wiring decision
Midea PC 01 needs voltage, current, module, and load checks before parts are quoted. The repair path depends on whether the fault is supply-side, wiring-side, or board-side.
Supply voltage and load checks separate building-side issues from unit-side faults.
Module or inverter faults need measured current and voltage evidence.
Repeated electrical trips should not be cleared repeatedly without diagnosis.
