Range Top Components; Maintop Burner Alignment; Low Flame Simmer Adjustments; Surface Burner Adjustments - GE Profile J2S968 SERIES Technical Service Manual

The range top components consist of the following: Maintop burner assembly (glass cooktop, burners,
burner caps and heads, igniter and switches, spark module), cooling fan, thermal switches, door lock
motor assembly, heat shields, and seals.

Surface Burner Adjustments

Standard adjustments to the air shutter and gas
metering orifices are not possible on sealed
burners.
If burner flames appear to be abnormal, check the
following:
• Check gas pressure available to the burners.
The required operating pressure is 4 in.
W.C.P. Natural Gas or 10 in. W.C.P. LP
(Propane) Gas. The pressure reading can be
taken at the broil, bake or top burner orifices.
• Check for drafts entering the burner box from
behind the range. Strong drafts beneath the
maintop can extinguish the burner and/or
cause erratic burner flames.
• Check for blockage or partial blockage of the
orifice. Inspect the orifice to be sure it has
been drilled on center and is free of debris or
burrs.
• Check the burner alignment (see Maintop
Burner Alignment)
• If the flames blow and lift off the burner and
the cause of the problem cannot be found,
installing an orifice with smaller diameter
openings may solve the problem. In high
altitude installations, above 6000 ft. (1829 m),
the orifices will usually have to be down-sized.

Maintop Burner Alignment

For proper operation of the burner, alignment of
the orifice holder, orifice, and air/gas mixer tube
must be correct. The alignment can be checked
by placing 7-mm or
orifice to exaggerate the angle. The nut-driver
should stand straight, indicating the alignment and
gas injection angle is correct. A slight downward
pressure may be necessary to seat the nut-driver
over the orifice-retainer ring.
If an angle adjustment is necessary remove the
burner cap, head, and bowl to inspect the orifice
holder and the brackets that hold them in place.
Adjust as necessary. A misaligned burner may
result in uneven flames around the burner head.

Low Flame Simmer Adjustments

Remove the surface control knob and locate the
adjustment screw on the valve body at about the
6-o'clock position.
Note: Low setting adjustments must be made
with 2 other burners in operation on a medium
setting. This procedure prevents the low flame
from being set too low, resulting in the flame being
extinguished when other burners are turned on.
