My air conditioner worked fine last night, but when I tried to turn it on today in the 101 heat, it displayed E1 (blinking). I've unplugged it because it would not let me turn it off either.

Can only but try this.Generic Procedures for Clearing an E1 Error

E1-Automatic filter clean reminder.

Turn the air conditioner OFF and unplug it. NOTE: The air conditioner must be unplugged for the automatic filter clean timer to reset.

Clean the filter. See the Care and Cleaning section in your use&care manual. After cleaning, replace the filter and plug the air conditioner back in.

It's time to call a professional. Call the manufacturer and ask them who they recommend in your area. Note :Some questions can be answered if you put enough information such as brand and model number.

Obviously it is problematic machine from the factory so it will suggest a replacement.

Yes, Heather, it's working correctly. It lives up to it's name "storage heater". When you turned it on last night, it heated and at the same time it was storing heat to be used later, during peak electrical use hours, without having to use any electricity. It's working as it should.

Hope this helped you and thanks for choosing FixYa.

try unplugging the unit and depressing the power switch for 10 seconds and then reconnect to power good luck

try turning it off holding buttons each individually in for 3 secs then in an hour plug back in ... the rep from Haier gave me this advice ... just waiting my hour now ... i also hear that the remote works for sure ...

I called haier about this error code. E1 indicates that a button on the control panel or the reomote is stuck. I was instructed to unplug the unit and push each button at least 5 times, one at a time. Plug the unit back in, and this fixed my problem with error E1 and the unit works fine.

This is not the most technical of solutions, but I had this exact same problem last night and I unplugged the air conditioner and left it that way overnight and this morning it had reset and was working again. I had tried everything I could think of to get it to work prior to just letting it be overnight. Hope this works for you, as well.
