    My midea 1.5 hp will be running and all of a sudden it goes off itself show EC on the display light. Then it’s not cold even after filling gas. It’s just two years and we hadly used it.

  5. Hi, I recently purchased a home with koolking split indoor model ms11m-09hrfn1-mx5w (4 zones). All was working well but then the heat started to not blow very hard Even at high fan speed, and the air became much less warm about a week ago. I live in Canada. Today two of the units showed the P2 error code. Would there be a leak anywhere in the line that could cause this error? Can you provide some help and guidance on what I should do to ensure diagnosis correctly and next steps? Thank you for your help.

    I installed a 4 multi zone midea mini split 9000btus. And after charging the system the unit ran good cool down. And then moments later on the indoor unit front display it reads to lines. What does that mean??

  18. Mohamed Jaffer L K

    Sir i need the solution forMidea cassette E3 error . . What is the problem sir? Please suggest. . .

  19. E9 error code on our Midea AC unit – rang the warranty and they let slip that this is the error code for a communication failure between the indoor and outdoor units.

    Its usually due to an outdoor unit not being secured properly and a connection coming loose. Check all wiring and connections. We also gave out outdoor unit a fonsi style nudge and it starting working again although we now have to do this every time the error code comes up but it seems to work in the short term – next step is to go after the guy who installed ours as he clearly did a bad job – this is the third time we’ve had to call Midea about this unit.

    roger,
    There is no Midea AC split system E9 error code in the database at this time.

    However we found this by digging further…..
    Midea AC Display = Error Code E9
    Malfunction or Protection = Voltage error

    richard sulatra,
    Midea AC Error Codes F1 and F3…
    F1 = Indoor unit coil outlet temperature sensor or connector of sensor is defective.
    F3 = Indoor unit coil outlet temperature sensor or connector of sensor is defective.

    -RR

  29. richard sulatra

    AC is Midea Air Conditioner.
    Every 5 minutes the evaporator and the AC are shutting down and it was indicated by the error F1 and F3.
    How can I fix this error?

  30. I have had the same problem with my split AC.
    Error code EC.
    Does exactly the same as described above.
    My model is not even listed on LG support site which doesn’t make things any easier, but they don’t seem to reference an error code “EC” for any of their units.
    Only info I have found elsewhere for other mfg units says this code means a faulty eeprom.

  31. Installed 2 x Midea inverter units yesterday – 2 different clients.
    Client 1 – 12000 BTU has a F3 error code on display (after 1 day)
    Client 2 – 18000 BTU has a EC erro code on display (after 1 day)

    What could be the problem?

  32. I have a Media AC, the indoor unit is working ok, but the lights on the display do not show up.
    I have tried the display button it makes no difference.

  33. I have indoor media …it always appear EC on its screen and stop working..I should switched off from the electricity and back again to work again…whats the problem please

  34. Media Split type MS12F1-09CR Keeps shutting off after a few minutes.
    LED display shows EC
    Installation technician has come twice, says no leak detected.
    When the unit is on, it cools.
    Please advise

  35. Media Split type MS12F1-09CR Keeps shutting off after a few minutes.
    LED display shows EC.
    I’ve had the installation company come check for leaks twice. No refrigerant leaks detected
    Unit cools when on but shuts off after 10-20 minutes. It won’t come on again unless turned on with remote.

  36. I have a Midea AC MS11D3.
    It started showing E3 error, maintenance came, they changed a piece from the outside unit.
    As soon as they left, E3 came back.
    Company came back, took all out of my ac, and told me it was my motor mistake, just had it replaced.
    They left E3 again. Some cracking sound come smoke come like from cold and the fan came so strong.

  37. My Mideast air con unit has started beeping every couple of seconds even when I switch it off at the wall. Does anyone know why ?

  38. DIY Project Help Tips

    Bryan,
    The error code E1 on a Midea split type AC will depend on the model number you have, check the model number you have and the see below…
    R and 9A series MIDEA AC = E1 error code = Indoor outdoor units communication protection error.
    Other MIDEA Air Conditioners including M5OA-36HRDN1-Q = E1 error code = No A Indoor unit coil outlet temperature sensor or connector of sensor is defective.
    -RR

  39. My Midea split type air conditioner started showing E1 error code on the indoor LED display is there a easy way to fix this?

  40. DIY Project Help Tips

    KAMRAN,
    If your MIDEA AC is cooling properly, what is wrong?
    Is the unit shutting off too early or not functioning 100%?
    -RR

  41. I have same problem with my Midea mini split 1 ton AC. I have checked any possible leakage but could not find any leakage as i have been told leakage leaves a black spot on the location of leakage. Also when my ac is running it cools properly. Which means freon is full. What else could it possibly be?

  42. DIY Project Help Tips

    bhushan sonawane,
    Do you have the model number so we may research your MIDEA air conditioner error code issue further?
    -RR

  43. bhushan sonawane

    The AC is on 10 minutes then the mcb trips but also error EC appears on the Midea AC.

  44. DIY Project Help Tips

    Benjamin,
    Midea AC error code EC = there is a possible refrigerant leak.
    Your Midea Air Conditioner has refrigerant leakage detection.
    Because of the installation layout of Midea Split air conditioners, it is possible that the AC unit can develop a refrigerant leak.
    The main effect will reduce the performance of your unit meaning it will not cool as well or not at all.
    Leaking too much refrigerant can damage the compressor.
    Midea split air conditioner systems will display an “EC” indicator on the indoor unit display screen.
    The EC error lets you know that there is a leak in the system.
    When you see the EC code on your Midea AC, you need to get the unit inspected before any damage can occur.
    -RR

  45. My Midea air conditioner keeps displays EC after about 10 mins into powering it on. I believe EC means error code but that doesn’t explain the main problem. How can I read this error code to understand the exact problem. Plus it does not chill and is always on 24.
