Solution: Here’s how you fix this issue:

  1. Look at the back panel of your smoker.
  2. There are 6 screws and a thin rubber gasket that can be peeled off. You’ll find two insulated wires. 
  3. If they look charred and some pieces crumble away when touched, this is the problem.
  4. Clean off the paddle to the heating element with a small wire brush.
  5. Crimple on new paddle connectors and slip on some shrink-wrap that will cover the wires and extend down past the end of the paddle to cover the heating element contacts. 
  6. Heat the shrink-wrap with a mini-torch. Insulate and weatherproof the connections that way.

As for the fan not working, you could get an aftermarket fan to replace it. The problem may also be in the switch. Check the switch for signs of melting. It could be your switch that needs a replacement. After you’ve fixed the issue, turn the grill back on. Your smoker is good to go again.
