Haier Air Conditioner Error E1 Code eHow

highly annoying issue error code E1. After hours
of fan operation, the error code E1 will appear on the seven segment
LED temperature display. This error code is intended as a reminder for
the user to clean the air filter. However, because the procedure
outlined in the user manual does not clear this error code as
indicated, and the appliance has a nonvolatile memory that cannot be
reset by simply unplugging it, the user of the appliance will become
mightily frustrated, standing in potentially sweltering heat watching
the appliance repeatedly shut down in the midst of operation with the
"E1" display flashing.

Believe it or not, that is what it does: if you unplug it to remove the
"E1" code from the display, and plug it back in and re-start it, it
will simply run for anywhere from a few minutes to a few hours, and
then merrily shut down again with the same flashing "E1" code.

So you will come home to a hot bedroom, living room, etc. unexpectedly,
and you will NOT be amused, as I was not.

Many people at this point, having put the manual under the canary or
some such, will simply return the unit and never buy another Sharp air
conditioner. But for the tech-savvy and search-adept, I offer the
following procedure to clear the nefarious E1 indication, and obtain

1. Power down the air conditioner using the "power" button on the front
panel.
2. Unplug the air conditioner from the wall socket.
3. Hold the front panel "power" button down and plug the air
conditioner in. Continue to hold the power button down as the machine
goes through a brief test sequence (fan & compressor each come on
briefly, etc). There is a "beep" sound at the end of the test sequence,
and the machine will be off. At this point, you can release the power
button.
4. Unplug the air conditioner.
5. Plug the air conditioner back in.
6. Congratulations! You should now be able to operate the air
conditioner normally for another 720 hours, but only if you followed
the instructions above EXACTLY.

Thanks for using fixya support..You have a wonderful day

Push buttons about five times each beforjust to make sure they are not stuck....then......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 and care manual. After cleaning, replace the filter and plug the air conditioner back in.

Other forums say the E1 code is because the AC thinks a button is stuck or because it's dirty, but almost all of them say to use the remote and it'll work ok.

Unfortunately, there's not much you can do. The E1 error code indicates a sensor shutdown. However, you can try turning the unit OFF & unplug it for 15 minute. Then plug it back in and turn it ON. If the electronics reset and reverted back to the original factory setting, you can set the controls as you like.

If you continue to get the E1 error code,, contact Haier Customer Support 1-877-337-3639.

Hope this helped you and thanks for choosing FixYa.

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.

Unfortunately, Haier for whatever reason does not list any error codes or what they indicate in their Owner's Manuals. You will need to contact Haier's Customer Support Dept 1-877-337-3639 to get an indication of what that error code means and how to solve the issue.

I hope this helps you and thanks for choosing FixYa.

These units have a capacitor that cannot be replaced. You'll need to buy the whole circuit board. I didn't bother with mine, I just went and bought another unit. 108 bucks.

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.

E1 means one of the buttons on the touchpad is pressed in. The remote will still operate the unit. You might have to pull the panel of, and check all the buttons. If all seems fine replace the control board. might not be worth it thou..
