Hi,

Hope someone can help me. As stated in the title, when ever I turn the a/c on it blows the 3 amp fuse on the board. The system works fine with heat on. It's only when I activate the a/c does it burn. I have no idea what is causing the fuse to blow. Does anyone have any ideas of where I can look? Also, I tried to disable the electronic air cleaner but it still blows. I don't know where else to look.

Thanks and much appreciated.

Pete

Check for a short in the wires going to oue outside A/C unit. Also check the 24 volt components in the A/C unit.
