  1. I have a GREE mini-split, purchased through Home Depot 6/10/20, installed Aug. 2020, failed 6/4/21, contacted support about 6/12/21 – only warranty after one year is parts. One repair person looked at it and said that the indoor unit not communicating with the oudtoor unit is a common issue. First error code was E4, then E6. After about 2 months, I received parts, sent to the repair person. Once those were installed, it ran for somewhere between an hour and a few hours, then produced E4. Turned power off and on, and it ran again for a short time, then displayed E6. E4 seems to be due to a faulty thermistor. Cost has doubled since purchase, and I would rather do this repair myself, but I don’t think I can buy parts. If, as the repair person said, this issue is likely to recur, it is not worth the cost of repair. (which defeats the purpose of reducing energy consumption due to mfg. waste) Do you have any options or suggestions? With some experience in computer hardware, can I remove and replace the board with the thermistor, and is there a source to purchase one? Or should I take this to a landfill??

  2. It has started getting cold here and I tried to turn the heat on on my Gree HVAC Unit but it just reads an error that looks like EE on the mini split, it will not blow any air out. What do I need to do?

The green light flashes 1 off 1, flashes 2 of 1, flashes 3 off 1 and then repeats. Can anybody shed some light on what is wrong and how I need to go about addressing the issue.

  9. Hello sir,
    I have gree inverter Ac last year I used this and in this year I start again maybe after 5 month and and now my ac is show U5 error ,
    Can you help me and tell me what is the problem?

  10. DEBORAH MORRICK

    It says F0 on the inside readout for my Gree A/C and Heat Unit. However , there is nothing showing red or yellow blinking outside. The unit has not been installed very long. IT has been approximately 11-12 months old .

  11. Mine shows F0 error message, but I’ve been running it on Heat. I don’t use it for A/C. It’s in a finished basement. Why would refrigerant be running low?

  13. E7 fixed when all zones are set for Heat – came on when I started turning on the heat for winter. I assume this will happen again when it’s time for AC to work again

  14. i have a gree mini split model viro9hp230v1b the unit in the bedroom reads E 7 what does that mean?

  15. I just had a Gree mini split system installed with 3 indoor units. The heat in one room will only come on if the living room unit is on, and the other unit doesn’t get warm at all. When I shut off the living room unit the other two will show E1 error codes. I’m so frustrated. The guy who installed can’t figure out the problem and it’s been several months since he put in the system

  16. My Gree has b7 on the display panel. Did not see this error in the list. What could cause this error?

    Thanks

    Paul

    Kashif Minhas,
    Gree AC Error Code H3 = Compressor Overload Protection.
    Check compressor and relay.
    Check for damaged or loose wiring inside AC unit.

    Do you know how to use a multimeter?
