Why won't the burner(s) light on my Thermos 4656110 Grill?

If the burner(s) on your Thermos Grill won't light, it could be due to no gas flow, an obstruction of gas flow, the regulator/valve cap not staying down, or disengagement of the burner to valve. Check to see if the LP tank is empty and clear the burner tubes. If needed, replace with Thermos parts and check the steps in the assembly instructions.
