    Contactor Fried On Heat Pump

    I have a Ruud heat pump about a year and a half old that just stopped working. The metal contact points on the contactor have obviously been getting very hot, melted some of the insulation on the line wire. What would be the cause of this?

    Bad or loose connection. Nothing to get alarmed about

    Improperly sized feed conductor, over amping compressor, poor connections, low line voltage. Have it checked by a licensed contractor before real (read EXPENSIVE) damage is done.
    A good HVAC tech knows how, an educated HVAC tech knows why!

    To add a few more, unit in confined causing pressure switch to cycle, dirty coil etc.

    Thanks everyone. I'll get it checked out. I think the biggest problem is the contactor says "Made in China" on it.
