Grill Electrode Removal and Replacement

On the grill, the electrode functions as a flame sensor – that is, if the
electrode does not heat up enough in a short time frame, the
electrode will close the solenoid valve to avoid gas build-up in the grill
burner. See Figure 63.

10. Make sure the electrode spade connector has been detached
from the electrode terminal (from under the burner box).
11. Remove and retain the screw that secures the electrode onto the
electrode bracket (see Figure 62 and Figure 63), and then remove
the electrode.
