William D Cynthiana , KY September 04, 2015 I came home to annoying beeping coming from the a/c it was switching from temp to timer with no way to control anything nothing worked After a little research, I decided the PC board was the problem. I ordered a new one( arrived in 2 days,wow)installed it and now it works great. Instead of buying a new a/c I repaired it and saved $$$. 16 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
