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.
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, or
improper air shutter adjustment.
Thoroughly clean burner by removing. See general
maintenance instructions. Open air shutter
slightly according to combustion air adjustment
instructions. (This must be done by a qualified gas
installer.)
Flames lift away from
burner, accompanied
by the smell of gas, and
possibly difficulties in
lighting.
Improper air shutter adjustment. Close air shutter slightly according to combustion
air adjustment instructions. (This must be done by
a qualified gas installer.)
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.
Lifting flames on burner.
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.
Close air shutter slightly - see previous problem.
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.
