    Tim check the cable from the topside control down to the PWA connection for breaks. If you don’t see any breaks in the cable and the led status doesn’t change when you press the up or down for temperature you could have a bad topside control panel. Send us the serial number for your spa if you would like a purchase link for a new topside control panel.
    The serial number can be found on the id sticker near the Sentry Control Box.

        Tim when you press the warmer button does the temperature number Led on the control panel go up and when you press the cooler button does the temperature number Led go down? Or does the Led number on the control panel stay constant/locked at 79 at all times no mattter what button you press?
