It turns off

is displayed temp less than 2 degrees than setpoint temperature ? its possible this situation will disallow the pump to go to high speed and the air infusers to work till spa heats back up , or can be a heater fault as well

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

A/c compressor works fine and the blower motor works and shutdown right? it is the problem with the blower resistor or with blower motor relay. try to direct the resistor irrespective of the speed. hope the problem may be solved.

You need to hard coat your Ip for the printer.

TRY THIS RESET FOR THE SECURITY SYSTEM.

PASS LOCK RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.

your dryer igniter, and or coils are shot.. change the drop in coils first...

Practice visual acuity technique! Look for bad solder connects==none found?? suspect flyback xformer.

tap it on its side then try to turn it on and see if it stays on if it does bad solder connections
