Midea air conditioner error codes. Indoor unit error code explanation: R series: ... E1, Indoor / outdoor units communication protection. E2, Zero-crossing signal error ... E4, Outdoor unit temp. sensor or connector of temp. sensor is defective.
the unit is not draining properly. unplug it from the current outlet, check behind there should be two places to drain the machine. unplug the two drain plugs in the back and let the water empty out. the e4 error message comes up when the unit is filling up with water.
WATER BUCKET IS THE FAULT the switch is more likely the cause try removing bucket and pressing lever manualy by hand then start it up again if it works you know the prob as this was mine the plastic connection aint the best
E4 means return air sensor error, if the error cannot reset may be the return air sensor is out of range or defective. But if the sensor is ok you need to replace the control board itself. The reading of return air sensor is 8k to 10k ohms @ 25deg. C temperature.
Using remote control "on" the unit, then push the C button of remote control, if the C display at the unit "off" the unit using also the remote control. Unplug the power supply then plug again and start the unit using the remote control. It the instruction above don't solve the problem, the return air sensor is out of range or the main board of the unit itself is defective. You need a qualified tech with this problem.
Start the unit and press the remote control at C if the display in the unit displays C, then turn off the unit using the remote control and plug out the ac supply. Plug the unit again and using the remote control turn on the unit. If the E4 still display there is something wrong with your air in sensor or the main board itself. Replacement of this parts needs a qualified technician.
