To avoid personal injury and/or property damage, it is important that Safe Servicing Practices be observed. The following are some limited examples

of safe practices:

1. DO NOT attempt a product repair if you have any doubts as to your ability to complete it in a safe and satisfactory manner.

2. Before servicing or moving an appliance:

• Remove the power cord from the electrical outlet, trip the circuit breaker to the OFF position, or remove the fuse.

• Turn off the gas supply.

• Turn off the water supply.

3. Never interfere with the proper operation of any safety device.

4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE. SUBSTITUTIONS MAY DEFEAT COMPLIANCE WITH

SAFETY STANDARDS SET FOR HOME APPLIANCES.

5. GROUNDING: The standard color coding for safety ground wires is GREEN, or GREEN with YELLOW STRIPES. Ground leads are

not to be used as current carrying conductors. It is EXTREMELY important that the service technician reestablish all safety grounds

prior to completion of service. Failure to do so will create a hazard.

6. Prior to returning the product to service, ensure that:

• All electrical connections are correct and secure

• All electrical leads are properly dressed and secured away from sharp edges, high-temperature components, and moving parts

• All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal parts and panels

• All safety grounds (both internal and external) are correctly and securely connected

• All panels are properly and securely reassembled

• All gas connections are secure and have been leak tested

Gas Cooktop Operation

Surface Burner Ignition Process

The ignition process of the surface burners on the 300 series and

500 series ranges is identical. Each surface burner is independntly

operated and controlled by a gas valve attached to a common manifold

pipe. The shaft of the valve extends through the front of the manifold

panel located just above the oven doorand a knob is installed on the

shaft.

To operate any surface burnerthe knob must ﬁrst be pushed inward

before it can be rotated. When the knob is rotated counterclockwisethe

valve opens to allow gas to ﬂow to the burner and activatethe electronic

spark modulewhich generates the spark to light the gas.

In order for the burner to light properlythe knob must be stopped at the

LITE position indicated on the knob by the lightning bolt graphic shown in

the illustration at right. If the knob is rotated beyond the LITE positionno

spark is generatedand the burner will not ignitehowevergas will continue

to ﬂow to thesurface burner.



Whenever any surface burner control knob is rotated to the LITE

positionthe spark module will generate a spark at all surface burners

simultaneouslyeven if other burners have already been lighted.

Activation of the spark module is accomplished by means of a switch

that ﬁts onto each surface burner control valve as seen in photo A below.

As the valve is rotatedthe switch cam is rotated.

The surface igniter switches are assembled in a continuous harness

and wired in a parallel circuitallowing any one of them to activate the

spark module. If one switch is defectivethey must all be replaced as an

assembly.

In the illustration abovethe eft Rear surface igniter switch is rotated

to the LITE positionclosing the contact in the switchand supplying L1

voltage to the spark module. The module ﬁres all surface burner igniters

at the same time.

Surface Burner Flame Characteristics

A properly operating burner will have clean blue ﬂames with no yellow

tipping, excessive noiseor lifting away from the burner head. Photo B

atright illustrates a typical ﬂame at high setting.

Yellow ﬂames indicate improper fueltoair ratio and can be caused by

improper gas pressure, improper conversion for use with LP gasor

contaminated fuel supply. 6XUIDFH%XUQHU)ODPH$GMXVWPHQW

The oven can be programmed to bake at any temperature from 170°F to

550°F (77°C to 287°C).

When broiling, the oven control has two selectable preset ranges, HI and

LO. When broiling on the HI setting, the maximum oven temperature is

550°F. When broiling on the LO setting, the maximum oven temperature

is 350°F.

In self-clean mode, the oven target temperature average is 825°F. The

actual oven temperatures will fluctuate between 810°F and 840°F during

the self-clean cycle to achieve this average temperature.

fter self-clean is completed, the oven door will remain locked until the

internal oven temperature is below 500°F.
