Our window unit stops working and flashes E1 on the display - when we press reset it starts again - for a while
I wrote the solution #1 and have an additional comment. This really does work!! I fixed my neighbor's AC unit by following the instructions for clearing the E1 code. The unit will not operate until the code is cleared. The page is titled: Customer assistance for air filters cleaning (E1 code) on Sharp Air Conditioners
Go to this address...it is on the first page. http://www.sharpusa.com/files/air_man_AFS60FX_S80FX_S85FX_R80FX.pdf You can also get to this address by clicking on the PDF symbol next to the link for the users guide. Clicking on the guide will not take you there.
