How do I trun on my unit? I pushed the On/ Off so much that it no longer works. I pushed the buttoms on the plug and it won't work. This is the serial code number as close as am to get it due to location that it is in the window. #AD09POE600A55AM3088 The owners manual is lost too. Please contact me @301 855-1985 and e-mail me. Brookslaw50@hotmail.com or teacherhannon@hotmail.com Also please send me a number where I may contact you and how I may get a manual.
