Midea aircon EH 00 / EH 0A error code & blinking light
Use this Midea EH 00 / EH 0A guide to capture the fault correctly and see what should be checked 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.
Choose the matching source row
The same visible code has more than one source-backed meaning. Match the model family, system type, or reporting unit before approving parts.
| Code | What it means | What to check first |
|---|---|---|
| Midea wall-mounted inverter error-code quick troubleshooting table | Indoor EEPROM malfunction | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
| Midea Serie Forest ONOFF MSAF / MOBA / MOCA / MOD wall-mounted split systems | Indoor EEPROM parameter error | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
| Midea Xtreme ONOFF R32 MSAGB wall-mounted fixed-speed systems | Indoor unit EEPROM parameter error | Match this row to the installed model or reporting unit, then use the source-specific checks below. |
What to do now
Use these steps before customer action or a parts quote.
Treat it as a fault signal
If EH 00 / EH 0A remains displayed or cooling is still abnormal, preserve the code and arrange diagnosis.
No manufacturer reset steps listed for EH 00 / EH 0A
Capture the complete EH 00 / EH 0A pattern 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 | Use the source quick-check path: Check incoming power and the indoor PCB. |
| Singapore / model note | Source is an official Midea regional wall-mounted inverter fault table; confirm the exact unit manual if the display differs on a Singapore model. |
| Singapore / model note | Official Midea Forest ONOFF wall-mounted service-manual row. Keep separate from the newer inverter EH / EL / EC / PC rows because fixed-speed models can show compact E/F/P codes. |
| Singapore / model note | Official Midea Xtreme ONOFF wall-mounted service-manual row. Keep separate from the newer inverter and compact Forest ONOFF rows because the source lists this fixed-speed family by EH / EL / EC / PC / PH display codes. |
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 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. |
| 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. |
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.
