Midea systems show their fault code directly in the indoor unit's display window — no button sequence needed. Midea has used two code generations: the older E/P/F codes and the newer EH/EL/EC/PC system, and both are covered below, along with the status codes (defrost, self-clean, Wi-Fi pairing) that look alarming but aren't faults at all.
Before you scroll: exact meanings can vary between model series — treat this as a well-informed starting point, not a service manual for your specific unit. And if a code appears alongside burning smells, breaker trips or water pouring from the unit, skip the table: switch off and call 0434 951 341.
How to find your Midea fault code
1
Wall splits — the code shows on the unit itself
- 1 No button sequence needed: the code appears in the indoor unit's display window (where the set temperature normally shows), either steadily or alternating with the temperature.
- 2 Codes start with E, P, F, or in the newer system EH / EL / EC / PC.
- 3 Midea's own advice: wait about 10 minutes (many protection codes self-clear), then switch off at the breaker, restore power and restart.
- 4 If the code comes back, note it down and book a technician rather than repeatedly resetting.
2
Units without a display — count the lamps
- 1 Count the Operation/Running lamp flashes in one burst, then look at what the Timer lamp is doing — it selects the code family.
- 2 Timer lamp OFF = an E/EH/EL/EC-type error (2 flashes = communication error, 6 = indoor sensors, 8 = refrigerant leak detection, 12 = outdoor fan).
- 3 Timer lamp ON = an older-style F-code (1 flash = overcurrent, 6 = outdoor fan).
- 4 Timer lamp FLASHING = a P/PC protection code (1 = overcurrent, 2 = voltage, 3 = overheat/pressure, 7 = IPM).
3
Ducted systems & outdoor units
- 1 Ducted and any unit on a KJR-series wired controller show the code directly on the controller screen, using the same table as wall splits.
- 2 Multi-split outdoor units have their own display showing codes plus status readouts (dF = defrosting, PH = pre-heat, LP = low ambient) — those status codes are not faults.
- 3 Single-split outdoor units signal via LED combinations on the board behind the service cover — technician territory.
Worth knowing: Midea changed code systems between generations — old E0/E1/F4 map to new EH 00/EL 01/EC 51, and in the new system H means indoor-side, C outdoor-side, E error and P protection. The same code can also mean different things on the indoor display versus the outdoor display (P1, P3 and P5 in particular). Always confirm against the manual for your exact model before ordering parts.

E-codes — indoor unit faults (older display style: most wall splits, multi-split indoor units, ducted/cassette)
| Code | What it means | Likely cause | What to do |
|---|---|---|---|
| AP | Wi-Fi/WLAN pairing (access-point) mode is active. Not a fault. | Smart-kit pairing triggered, often by pressing the LED/DO NOT DISTURB button 7 times; exits by itself or after pairing completes. | Try this first |
| CL | Filter-clean reminder on most models (Active Clean / self-clean running on some newer ranges). Not a fault. | Accumulated run-hours trigger the reminder; or the self-clean cycle is running (20–30 min). | Try this first |
| CP | Unit switched off by the (wired) remote controller. Not a fault. | Remote-off state; turn the unit back on from the controlling remote. | Try this first |
| E0 (also EA) | Indoor unit EEPROM (memory chip) parameter error — the indoor control board has lost or corrupted its settings | Control board memory glitch after a power spike or brown-out; failed indoor main PCB | Try this first Switch off at the isolator/breaker for 2 minutes and restart; if E0 returns, book a technician — the indoor board usually needs replacing |
| E1 | Indoor and outdoor units have stopped talking to each other (communication error) | Loose or damaged interconnect wiring between the units, wiring not to the diagram, electrical interference, or a failed indoor/outdoor board | Try this first Power cycle at the breaker for 2 minutes; if E1 comes straight back, book a service call — the interconnect wiring must be checked by a licensed tech |
| E2 | Zero-crossing signal detection error — the indoor board can't read the mains AC waveform properly | Unstable power supply or a faulty indoor control board | Book a service |
| E3 | Indoor fan speed is out of control (running outside its normal range) | Fan obstructed or airflow choked by dirty filters, failed indoor fan motor, or fan-drive fault on the PCB | Try this first Turn the unit off, clean the return-air filters and check nothing is fouling the fan barrel, then restart; if the code persists the fan motor needs a technician |
| E4 | Indoor room temperature sensor (T1) is open-circuit or short-circuited | Unplugged, damaged or failed room air sensor, or corroded connector | Book a service |
| E5 | Indoor evaporator coil temperature sensor (T2) is open-circuit or short-circuited | Failed or dislodged coil sensor, or damaged sensor lead | Book a service |
| E7 | Outdoor fan speed out of control on most models; on some models a communication error between the outdoor main chip and compressor-drive chip, or display-board fault (model-dependent). | Seized/obstructed outdoor fan, failed outdoor fan motor or its driver, or outdoor PCB fault. | Book a service |
| EC | Refrigerant leak detected — the system senses it is losing gas | Refrigerant leak at a flare joint, coil or pipework; system undercharged | Switch off & call |
| EE | Water level alarm — condensate is not draining (ducted and cassette units with a drain pump) | Blocked condensate drain, failed drain pump, or stuck float switch | Try this first Switch the unit off and check the condensate drain outlet isn't kinked or blocked; if water has built up or the code returns, book a technician before water damage occurs |
| Eb (new system: EH 0b) | Communication error between the indoor main board and the display board. | Loose or damaged display-board ribbon/connector, or a faulty indoor main board. (E6 is a different fault: on outdoor displays it's PFC module protection; on older R/9V/9A-series units it's a room or coil sensor fault.) | Book a service |
| dF | Defrost in progress — the outdoor unit is melting ice off its coil in heating mode. Indoor fan pauses and steam may rise from the outdoor unit. Not a fault; the single most common 'code' customers report in winter. | Normal defrost cycle in cold/humid weather. Only a concern if it repeats constantly or heating never resumes (then possible refrigerant or sensor issue). | Try this first |
F-codes — outdoor-side faults shown on the indoor display (older style)
| Code | What it means | Likely cause | What to do |
|---|---|---|---|
| F0 | Overload/over-current protection — the system is drawing too much current | Overcharged or restricted refrigerant circuit, failing compressor, low voltage, or blocked condenser | Switch off & call |

| FA | Communication fault between the two chips on the indoor board (A6 ducted units) | Indoor control board fault | Book a service |
| FC / SC | FC = forced-cooling (commissioning/test) mode; SC = self-clean cycle running. Neither is a fault. | FC is entered via the unit's manual button during service/commissioning — power-cycle to exit. SC runs 20–30 min after the clean function is selected. | Try this first |
| FL 09 | Indoor and outdoor units are mismatched (incompatible model pairing detected). | Wrong indoor/outdoor combination installed, or capacity/dip-switch configuration error at installation. | Book a service |

| P2 | High-temperature protection of compressor top or IPM module (high pressure on some models) | Blocked condenser airflow, refrigerant issue, or failing compressor | Switch off & call |
| P3 | On the indoor display of a multi-split: low outdoor ambient temperature protection. Shown on the outdoor unit's own display, P3 instead means compressor over-current protection. | Outdoor temperature below the unit's operating limit; not a component failure | Try this first No action needed — the unit resumes when the outdoor temperature rises; only book service if it shows in mild weather |
| P4 | Inverter compressor drive error — the outdoor board can't drive the compressor properly | Compressor winding fault, failed inverter drive board, or wiring fault | Switch off & call |
| P5 | On a multi-split outdoor display: condenser high-temperature protection. On some older residential series, P5 instead means inverter module protection. | Condenser coil clogged with dirt/debris, airflow blocked, or very hot install location | Try this first Switch off and clear debris, plants and rubbish from around the outdoor unit so air can flow; if it trips again, book a technician |

Frequently Asked Questions
Where does my Midea show its fault code?
In the display window on the indoor unit — the same window that shows the set temperature. The code either sits there steadily or alternates with the temperature. Units without a display signal via the Operation and Timer lamps instead; the flash-counting method is above the tables.
My Midea shows dF / CL / FP — is something wrong?
No. Those are status readouts, not faults: dF means the outdoor unit is defrosting (normal in cold-weather heating), CL is a filter-clean reminder, and FP means frost-protection heating is holding the room at about 8°C. They're listed in the status section on this page so you can stop worrying about them.
Why do the same codes mean different things on my outdoor unit?
Because Midea's indoor and outdoor displays use overlapping code letters for different faults — P1, P3 and P5 in particular mean one thing on the indoor display and something else on the outdoor one. Our tables note which display each meaning belongs to.
What are the EH, EL and EC codes?
They're Midea's newer code system, used on current ranges like Xtreme Save. The letter after E tells you where: H = indoor side, L = other/system, C = outdoor side. Old codes map across (E0 → EH 00, E1 → EL 01, F4 → EC 51), and both generations are in the tables here.
