Reset air conditioner

This did it for me! Same procedure but its described a little more thoroughly here...

Unplug it. Wait a few minutes. Hold in the Power button while plugging it back in and keep the button held down until a beep is heard (~5 sec). Unplug the air conditioner, then plug it in again.
Note: some units require using the Mode switch, rather than Power.

Is it possible you still have the owner manual? It will have the reset codes for you listed. Also, check the filter, make sure it is clean and that the evap and condenser are clean as well.

Thanks

I read on another site that there is no solution. Word for word the person stated that the damn thing was "fried." and to take it back. Not sure what he meant by taking it back? Certainly he was prematurely assuming that the AC unit was new. Well, mine is not new. Actually, I bought it a year ago today, and it blew out today. Tomorrow it will be out of warranty. Imagine that ****!! I have owned 3 AC's in the last 5 years and each time they blew out, it was on July 15th, which is also my birthday. Three birthdays ruined by this ****, and then this is even speaking of the ODDS of this happening three times on the same day. Come on now, where are my lottery winnings???

Your power botton went bad. I took the circuit board out and chanded the timing switch with the power switch and the E1 went away and the AC unit works fine now.
