Why is the display showing E"#"-F"#," for example, E1-F2?
Answer Is "PF" displayed on the control?
A temporary power failure has been detected. Press the Stop/Clear keypad to reset your control. You may need to reset your clock.
Is the display showing E0-F5?
The Self-Cleaning latch may be interfering with the oven door causing the Self-Cleaning cycle not to work. If the oven door is open and will not lock, press Stop/Clear to clear the display, press and hold the door switch plunger (located in the upper-right corner of the oven front), and the door latch will unlock. If the oven door is closed and locked, press Stop/Clear to clear the display; apply pressure to the upper-right corner of the oven door, and the door will unlock.
Is the display showing E"#"-F"#," for example, E1-F2?
You will need to schedule service.

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.

These are settings for the Timex SPORTS 1440 Magnetism (5b841 -W163US)
These are for the 4 button SPORTS 1440 (not 6 button) - they will also work for the 1440 SPORTS "Informer" model wrist watch - you will NOT find these instructions on the Timex website - only the 6 button which will not work on these watches is on that site!
