The unit flashes when plugged in and will not funtion or even flash unless it is plugged in. It was working fine until it quit without any notice. Any suggestions / tips? Thanks
E1 indicates Filter needs replacing/Cleaning , this code flashes after 720 hours of operation time.
Disconnect the power plug
Clean or replace filter
HOLD DOWN (dont let go) Of the ON/OFF button and plug the unit back up and continue to hold the ON/OFF button until you hear a beep
After the beep unplug your A/C
Then plug it back up to and turn it on for normal operation
IF THIS FAILS TO REMOVE THE CODE
UNPLUG A/C THEN HOLD DOWN THE MODE BUTTON AND PLUG IT UP STILL HOLDING THE MODE BUTTON UNTIL YOU HEAR A BEEP.
UNPLUG UNIT AND THEN PLUG IT BACK UP AND ONE OF THESE 2 STEPS WILL FIX YOUR PROBLEM UNLESS THERE IS A MAJOR PROBLEM IN THE CONTROL BOARDS
