You can just take the panel off to the control and look for dirt and grime. then take a can of compressed air that you can by at a local hardwar store or office supply and blow around the buttons. also you can unplug the unit and let it reset itself sometimes this will break the circuit to the button and then it should work normally. you can also tap on the button(just enough that it will click like tapping on a window) these should help you...please rate thanks

Hey, do you have the remote? try using the remote. to unstuck a button.. well check the buttons, the ac may only think a button is stuck when its actually not. have you tried unplugging for a while?

(E1, failed keystroke circuit / stuck button)

Hi-

You will have to open up the unit and check on the filters for dust and on the control panel area, check the membranes on the airconditon panel or the button, clean the dirt surrounding it as well.

keep us posted

The e-1 error means servicing is required as something is blocking the ventillations.


pls do rate the solution

thanks.
