I have had my Guru for about 3 years. Has anyone experienced failure with the probes. The last couple of cooks my pit probe will suddenly start beeping low then it will register at 400+ degrees. I will wiggle and straighten the wires some and it will correct itself. Also, from time to time the food probe will register just dashes. I'm thinking my pit and food wires may be shot from all the winding up and some kinks that I see. I check the wires to make sure they are clicked in the unit. Has anyone ever sent a unit in to get it checked out and refurbished? May just order some probes and see how it goes. Right now, I'm having to wake up and make sure everything is alright or the neighbor will call and say my smokers beeping..lol.
