Gree Air Conditioners Error Codes

The fault code is deduced from the number of times the green LED flashes, blocking unit operation.

C5:Malfunction of connector jumper: Check if the connector jumper contacts properly. If the PCB is to be replaced, please take off the old for the new PCB

F1:Malfunction of indoor ambient temperature sensor:Check if indoor room temperature sensor is connected properly.

F2:Malfunction of evaporator temperature sensor:Check if the evaporator temperature is connected properly.

H1:Defrosting:It is normal

H6:Indoor fan block:Check if terminal of the indoor motor is connected properly. Replace the fan motor or the indoor board if disabled.

    I have spilet 42000gree.when want comperssor start disply on lcd error e1 and no work spilet.howe I can fixed these error

  2. tariq javed says:

    What is the solution for e6 error in gree ac ?
    i am stuck …. plzzz reply me how to set up communication between indoor and outdoor again and overcome the error

    • Vincent says:

      communication error, exterior pcb failure, or it’s the voltage filter who died or wired burned, so the pcb doesnt receive 240volt, maybe just 120.

      • peter malouhos says:

        where is the voltage filter located on outside unit, on gree neo 36 I have an e6 error code, replaced both inside and outside boards, and i still get an immediate e6 code when turning on unit!!!

    • marjon says:

      e6-means error communication between indoor and outdoor.

  3. Joseph buttigieg says:

    ı have gree aırcondıtıon , model code (gwh12mb-k3dna3a/ı) showıng an error code of (h5), and from the lıst above says that the error code corespond to (ıpm current protectıon) what does ıt means ? and please some to tıp to repaır ıt .
    thanks ın advance

    • Roger Lee says:

      H5 is an over heat / over current protection. With the power off check all the connections down the the compressor, while there check the compressor winding (0.5 ohms ~ 2 ohms and to earth >500 M ohms)
      Check on the main outdoor PCB for a short between P and N and P or N to U V W, using a diode checker, check between P and U V W and then between U V W and N, these should be the same (0.3 V ~ 0.7 V) If any of these are shorted or are different to the rest then the outdoor PCB needs to be changed.
      This fault could also occur if the unit was placed under a larger load, but once turned off and allowed to cool down should restart.

  4. Jitendra gupta says:

    Error E6

    • Roger Lee says:

      E6 is an communication error, check that all of the wires are connected correctly and that none have come loose or broken.
      On the outdoor unit there are three LED’s, if any of these LED’s are on then the IC has failed so you need to change the main outdoor PCB.
      If the green LED blinks once every second then comms is ok.
      If the red LED is blinking check the voltage between terminal 2 and the neutral. The voltage should swing between zero and 20 VAC, if it does, the indoor has sent a signal and this has not been received by the outdoor, replace the outdoor PCB. If the voltage does not change, then no signal has been sent, check the interconnecting wiring and check for loose connections before replacing the indoor PCB

  7. Cathy Wadkins says:

    I have a split system and I have had it for 1 year right at it, but I have had 2 units leak water down my wall and floor in the house and I had the outside drains blowed out but now all my units are sitting on a Error code E3.
    Can you tell me what’s wrong with it, before I got to run
    This unit for the summer it had a code E3 and it cost me
    $500.00 for the Freeon not enough put in it.

    • Vincent says:

      You have a leak of gaz, units must have frozen

      • Vincent says:

        the technicien must check for leak of gaz, if units is new, i would check first flares nut, and behing the head wall units has well.

        The leak must be fixed. 500$ of R410 in a split type? he must have been there for hours i guess…..

  18. andrea says:

    Hi I have moved into a brand new apartment with a brand new GREE air conditioner in my bedroom, after a 2 hours or so it goes into E2 and stops. I understand the description of this error but how do I prevent it? The unit is brand new and I leave it on 22/23 degrees cool and low fan / economy. Why is the bulb getting so cold that it has to stop? I have to reset the aircon on my main switch box in order to get it going again. Please advise what can be done as it is brand new and should not require service, will it be a warranty thing? .. very frustrating. Your help will be appreciated.

    I have a neo high wall ductless ac and heating system. When i cut it on says E7 on the display on wall unit.i read whole manuel and it does not mention any E7. My remote says 78*f and a clock face says 18:51 which is time. What is E7 and how do i fix it.

    • Anthony Serrato says:

      I had the same problem, looked everywhere for the mythical E7 code (which by the way I have yet to find) and thought was lost until I read the manual again. But this time I didn’t just skim through it looking for a specific thing. Ive got 4 of the Gree Model #: NEO09HP230V1A’s. Whats happening is your trying to run the heat in one room and have the other room(s) cooling or something along the lines of that correct? Well the system isn’t designed to do that. its with one or the other. Either you have to have them all on heat mode, one off and other on heat mode, in my case if i wanted heat in just one room id had to switch 3 off and one on heat, 2 on heat and the other 2 off…..You following the pattern? its just like having an old 2 ton pac unit. Some concept applies. the system is only designed for one or the other.
