    AF-S60FX, AF-S80FX, AF-S85FX, and AF-R80FX

    may experience the following (highly annoying) issue. After 720 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
    another 720 hours of cooling bliss:

    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.

    If you doubt the veracity of this information, or it does not work as
    expected, you can get it directly from the source at:

    1-800-237-4277

    which is the Sharp customer service line. But, you'll need to call
    between 7 AM and 7 PM US Central time, and have your model number and
    serial number ready.

    Beware, there a a few versions of this sequence floating around on the
    net, and some of them DO NOT work.

    What do you think the odds are that new production of these models has
    removed this "feature"?

    Re: How To Clear Sharp Air Conditioner E1

    Thank you! Thank you! Thank you! I came home from work tonight in mid-90
    degree temps & a sweltering house. The AC unit was flashing E1 & of
    course, the manual wasn't in the drawer it was supposed to be in. I
    unplugged it & it reset. When I walked out 30" later, it was off again.
    Thank God for the Internet!! I searched Sharp AC plus E1 and found your
    post. I followed your directions & so far, so good. Thanks!!!

    Thanks for posting! I tired that and it kept erroring - so I called the company - and they gave me the same instructions - then it errored again
    So I called again and they gave me this alternative:

    Sharp Air Conditioner error E1
    Disconnect Power
    Hold down MODE and plug in at same time until you hear a beep – unit will start by self
    Turn power off – DO NOT UNPLUG
    Turn back on

    Best of luck - I know I will not be buying a Sharp when it comes time to purchase a new air conditioner.
