Midea aircon EH 00 / EH 0A error code & blinking light
Use this Midea EH 00 / EH 0A guide to decide when to stop resetting, what to capture, and what to check before parts are quoted. Match the model first; same-looking signals can point to different rows.
What does Midea EH 00 / EH 0A mean?
Midea EH 00 / EH 0A is listed as indoor EEPROM malfunction, indoor EEPROM parameter error, and indoor unit EEPROM parameter error in Inverter Split, Wall-Mounted Split, Standard Non-Inverter rows such as Midea wall-mounted inverter error-code quick troubleshooting table, Midea Serie Forest ONOFF MSAF / MOBA / MOCA / MOD wall-mounted split systems. The loaded row is source-backed by official diagnostic material. Do not collapse this code across model families; use the model, series, or system type to choose the right row. 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 another reset or parts quote.
Treat it as a fault signal
If EH 00 / EH 0A returns or cooling is still abnormal, stop treating it as a simple reset issue.
Reset EH 00 / EH 0A once
Capture the EH 00 / EH 0A pattern first, then power-cycle once only and note whether the same fault returns.

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 EH 00 / EH 0A, take a clear display photo and blinking-light video if the unit shows one. | Confirm which PCB or board input EH 00 / EH 0A points to on the source row. |
| Capture the Midea indoor and outdoor model stickers so the correct family row is used. | Check power supply, fuses, connectors, wiring, and board indicators. |
| Note whether one room, several rooms, or the whole system is affected, plus whether it returns after one reset. | 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 EH 00 / EH 0A. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same EH 00 / EH 0A 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 same code appears with different meanings in the source rows. | Model family, source table, and system type decide which meaning applies before parts are quoted. |
| The model belongs to Inverter Split, Wall-Mounted Split, Standard Non-Inverter rows such as Midea wall-mounted inverter error-code quick troubleshooting table, Midea Serie Forest ONOFF MSAF / MOBA / MOCA / MOD wall-mounted split systems. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
PCB repair or replacement decision
Midea EH 00 / EH 0A 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.
