So with operation and defrost blinking continuously on indoor unit, it would be error e6 right? Its midea msg09hrn1.
Thanks
Hello ,my midea has an error code P0 what is the cause and how can i fix it....please!Thanks.
Error code E24?
my midea mga-f30w/s show "EC" in lcd (interior unit) and "E2" in display of motherboard (exterior unit). help please!
E3 how
If indoor unit showing E3 it means fan speed beyond the control . Most probably electronic control board will be a faulty
