Hi all, my several year old RT680 will no longer start. It flashes through the model and firmware rev but when I press the ON button it doesn't start up. The power is there because the interior light turns on and off but no luck getting the grill to turn on. Last time I used it I had a heck of a time getting it to start, like I had to press the button repeatedly and it finally turned on. This time no go. I suspect too many years out in the Florida elements did a number on the circuit board. Any idea how much a replacement costs? Also, can I upgrade to a wifi controller while I'm at it?
