Troubleshooting
Problem Possible Causes Solution
Low heat / Low flame when
valve turned to high. Improper lighting procedure.
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.
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.
Ensure sear plates are installed with the holes towards
the front and the slots on the bottom. See assembly
instructions.
Preheat grill with both 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. Thoroughly clean burner by removing. See general
maintenance instructions.
Burner will not light with the
igniter, but will light with a
match. Dead battery / or installed
incorrectly.
Loose electrode wire or
switch terminal wires.
Wrong replacement igniter.
Improper gap at electrode tip.
Replace with heavy duty 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.
One spark systems must use a one spark igniter.
Ensure that the collector box is tight and the gap
between the electrode end and the collector box is
between 1/8” - 3/16” (3mm-5mm).
The gap can be
adjusted by bending the box in or out.
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. Plugged ports along back of
burner. Clean burner ports. See burner maintenance
instructions.
“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.
