SOURCE: WRAC has E4 on display
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.

5 flashing is ' compressor drive' and check the high pressure, condenser fan motor capacitor for proper running

Sound like a defective receiver board. Have this checked. Also check to see that your remote transmits. Hold the top part of the remote to your phone or digital camera lens. press a button and a light should appear on the screen of your phone or digital camera screen.

there are 3 drain holes in the primary pan right underneath the evaporator that need to be clean with a pipe cleaner or a wire of somekind and there is also a secondary drain behind it that will work only if the unit is 100% level. To access the primary drain pan you have to take all the screws of the back cover 5 on each side and 3 in the center above the electric cord and behind the air filter and only then will you be able to see these very small holes. Use a flashlight to make sure. Have fun!Reply
