What does E1 mean in maintenance book/Sharp Air-Conditioner

Question

My air-conditioner (Sharp) keeps shutting off and E1 appears on the screen. I have re-set it several times but keeps going off. The air filter is clean. What to do?

Answer 1

This is a reminder to clean the air filter.  It happens every 720 hours of operation.  Here are the steps to get it back up and running:

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.
