Crossover Ignition System Operations
If the Crossover Ignition System fails to ignite the Left
burner, light the Left burner with a match. If the Left
burner lights with a match, then check the Crossover
Ignition System.
■ Check that both the white and black ignition wires are
attached properly. Figure 18.
■ Check that the Crossover Ignition button pushes the
igniter (button) down, and returns to the up position.
■ Check to see if the igniter is loose in the frame.
Tighten if necessary; See Step “Install igniter” for
correct procedure.
If the Crossover Ignition System still fails to light, contact
Weber-Stephen Customer Service.
