STEP ONE: I S O L AT I N G T H E P RO B L E M
NOTE: Before addressing any specific prob-
lem the unit may have, it is advisable to help isolate
the nature of the problem by running a general check
of the 1) Gas Supply and 2) Electrical Supply. The
following procedure will narrow the possibilities and
help direct you to the source of the problem. A
detailed Troubleshooting section with specific symp-
toms and likely corrective courses of action follows
each sub-assembly Partlist section. Wiring diagrams
and schematics are also included to assist in trou-
bleshooting.
CHECK GAS SUPPLY
First, check to see if the gas has been turned on.
Next, gain access to the regulator by removing
the grates over the cooktop burners on the far left
hand side of the cooktop. Beneath the grates, towards
the rear of the burner box, the regulator is located
between the manifold and rear incoming gas line.
Check the top of the regulator to see that it is set up
for the type of gas supplied to the unit. The cap on
top of the regulator indicates whether the unit is set
up for NATURAL or L.P. gas.
When the gas supply is on, check the gas
pressure with a manometer. The front main open top
burner orifice is the most convenient place to check
gas pressure. To access the main burner orifice,
remove the four (4) screws that hold the burner hang-
er down and A) move aside the burner assembly or B)
disconnect the igniter wires and remove the entire
burner / hanger assembly. Hook up a flexible line to
the main burner orifice, turn that burner on... the
pressure should read 5.0" W.C. for Natural Gas, and
10.0" W.C. for L.P. Gas. Turn on other burners and
check for an excessive drop in pressure. A large drop

in pressure indicates a gas supply problem related to
installation, not covered by service warranty.
CHECK ELECTRICAL SUPPLY
First, check to see if the electricity has been
turned on.
Next, check power to the cord in the back of
the range and at the wall receptacle. If power is OK
there, the next area to check will be at the service dis-
connect located behind the valve panel. The Valve
Panel can be removed by removing the five (5) screws
that hold it in place. Two (2) screws are located at
each end of the panel, while one (1) screw (painted
Red) behind a Burner Control knob must also be
removed before the valve panel can be removed.
Once the Valve Panel has been removed, unplug and
check for power to the female side of the plug. 220-
240V 120 between red /white 120 between black /
white 240 between red & black
Check for power at the Terminal Blocks,
(Black & Red = Live, White = Neutral)
