    It must be a NEST! private joke

    My guess is the control board is defective and the thig-a-ma-gig (that is a technical term) that is supposed to shut it off when the room reaches the thermostat setting ain't working right. or would it be it ain't working wrongly?

    There would be a model number on that GE unit. with that number, I could look up the I/O manual and the trouble shooting manual to help answer your query.

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

    How high do you want it to go? Did you stock up on deodorant?
    I'm assuming it's a HP so that's about max.
