    I've heard of the shield for the coax for the cable ending up carrying the neutral current too.

    Folks - it has been two weeks since the foil discovery and my AC has worked flawlessly since then. Can't thank you enough for hanging in there with me to diagnose the issue! You guys rock!

    It is time to reinstall the Limit Switch. You should take the front panel off of the furnace (at least partially) and secure the insulation with some sort of foil tape or perhaps replace that insulation with something new. If you are not up for the DIY task, then you should look into having a pro put it on his schedule as a "fill in job" over the next few months.

    After you make that expensive repair and you still have the same problem, What will you check next?

    I know this is an old thread but I stumbled upon it in a Google search.

    My sole reason for registering and posting is to thank everyone in this thread for their efforts. From the original poster stubbornly keeping at it to the experienced posters who kept being willing to help, it was a fascinating read.

    No parts changers to be seen here. Only diagnostics experts and one very persistent home owner!

    Thanks everyone.
