Midea Aircon PC 01 Error Code
Use this Midea PC 01 error code guide to decide when to stop resetting, what to capture, and what to check 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. The loaded row is source-backed by official 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 another reset or 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.
Reset PC 01 once
Capture the PC 01 display, then reset once only if there is no burning smell, repeated trip, or hot outdoor unit.

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 resetting 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. |
| Note whether one room, several rooms, or the whole system is affected, plus whether it returns after one reset. | 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, source-table, 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. | The shared outdoor side, power path, communication trunk, or refrigerant circuit needs priority checking. |
| The fault returns immediately after one reset. | 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 Inverter Split rows such as Midea wall-mounted inverter error-code quick troubleshooting table. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
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.
