Troubleshooting
Problem Possible Causes Solution
Low heat / Low flame when
valve turned to high.
For propane - improper lighting
procedure.
For natural gas - undersized supply
line.
For both gases - improper
preheating.
Ensure lighting procedure is followed
carefully. All gas grill valves must be in the
off position when the tank valve is turned
on. Turn tank on slowly to allow pressure to
equalize. See lighting instructions.
Pipe must be sized according to installation
code.
Preheat grill with both main burners on high
for 10 to 15 minutes.
Excessive flare-ups/uneven
heat.
Sear plates installed incorrectly.
Improper preheating.
Excessive grease and ash build on
sear plates and in drip pan.
See assembly instructions.
Preheat grill with main burners on high for
10 to 15 minutes.
Clean sear plates and drip pan regularly. Do
not line pan with aluminum foil. Refer to
cleaning instructions.
Burners burn with yellow
flame, accompanied by the
smell of gas.
Possible spider web or other debris
in burner.
Thoroughly clean burner by removing. See
general maintenance instructions.
Rear and Side burners will
not light with the igniter, but
will light with a match.
Dead battery / or installed
incorrectly.
Loose electrode wire or switch
terminal wires.
Replace with heavy duty premium battery.
Check that electrode wire is firmly pushed
onto the terminal on the back of the
igniter. Check that the lead wires from the
module to the ignition switch (if equipped)
are firmly pushed onto their respective
terminals.
Main burner will not light
with the igniter, but will light
with a match.
Jet-fire outlet is dirty or clogged. Clean jet-fire outlet with a soft bristle brush.
Humming regulator. Normal occurrence on hot days. This is not a defect. It is caused by internal
vibrations in the regulator and does not
affect the performance or safety of the
gas grill. Humming regulators will not be
replaced.
Burners will not cross light
each other.
Dirty or corroded cross light
brackets.
Clean or replace as required.
“Paint” appears to be peeling
inside lid or hood.
Grease build-up on inside surfaces. This is not a defect. The finish on the lid
and hood is porcelain, and will not peel.
The peeling is caused by hardened grease,
which dries into paint-like shards, that flake
off. Regular cleaning will prevent this. See
cleaning instructions.
Burner output on “high”
setting is too low. (Rumbling
noise and fluttering blue
flame at burner surface.)
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Spider webs or other matter in

Check gas level in propane cylinder.
Reposition supply hose as necessary.
