May 27, 2014Gree code E7 mode conflict when I just want it to run the fan?
I do not know gree products specifically, but most many split systems. You cannot play with fan modes in heating, especially because refrigerant will usually always travel through the piping. Even only when one head is calling because it needs to move a minimal round of refrigerant to make the system work properly. And you run the risk of overheating, the zone that you don't want to heat at all, which is why you're turning the indoor unit off and only trying to run the fan. More on reddit.com

November 17, 2025Washed my Haier Mini Split outdoor coils and now have an E7 Code
Im not familiar with Haier in particular but ive looked up E7 and it seems to be a communication error. This means the outdoor board cannot communicate well with the indoor units. This may happen is water damaged the board but you did your best to not make that happen so I dont know. You can try to turn the breakers off again for a day and put it back on again. Check the wires if they got loose (on the terminal on the right side of the unit (while breaker is off of course). If nothing works, the outside boards might need replacing. More on reddit.com

Do I need to shut power off at the breaker to clear E7?
Usually no. Turning all indoor heads off, waiting about a minute, then restarting them in the same mode is typically enough. A breaker reset is only recommended if the system is completely unresponsive.
