  1. I’ve put two ignitors in and both failed to get hot. There are no codes showing up. I examined the connections all way to controller. No loose connections. I’m guessing it needs a new controller??

    • Hi Kelly

      Look out for rust in the ignition chamber and clean it. Also, take a look at the temperature control and check for uneven heat. Reset your Grill and update it.

      Hope you will get the solution.
