Gas Manifold; Ignitor Switches; Maintop Burner Valves - LG LRG30855ST Technical Service Manual

Ignitor Switches

The ignitor switches are located inside the
manifold panel and are attached to each maintop
burner valve. The back of each switch is molded
to conform to the front of the burner valve and
is locked in place by 2 tabs. All switches are
wired to a single harness and can be replaced
separately.
Note: To replace the ignitor switch for the left or
right rear burner, it is necessary to remove the left
or right rear burner valve from the gas manifold.
To remove the ignitor switch:
Caution: The 2 lock tabs on each ignitor switch
are fragile. Tab breakage can occur if excessive
release pressure is applied.
1. Remove the manifold panel. (See
