Official Preway range parts

Most common Preway oven parts and range parts that need replacing

• Surface burner spark module. The surface burner spark module is in the ignition circuit for the gas surface burners. When a surface burner control knob is turned to the 'Lite' position, it provides voltage to the spark electrodes on the gas surface burners. If the surface spark module fails to provide the electrodes with voltage, then it should be replaced.
• Surface burner spark igniter switch. The igniter switch is an electrical switch on the stem of the gas surface burner control valve. This switch completes a circuit to the surface burner spark module, causing the burner igniters to spark when the burner switch is turned to the Lite position. Replace the burner igniter switch if the burners don't spark when you turn the burner control knob to the Lite position or if igniters spark constantly even when the burner knobs are in the Off position.
• Oven burner igniter. Most gas ovens have a glow-bar oven igniter and a safety gas valve. Those components are connected in a series-type electrical circuit. When the glow-bar oven igniter is hot enough to safely ignite the gas, the safety gas valve opens. Replace the oven igniter if doesn't glow, or if it glows but doesn't get hot enough to open the gas valve. Some ovens have a separate igniter for the bake burner and the broiler burner, which operate on the same principle.

What to do when a surface burner won't spark or ignite on your Preway range

A surface burner igniter switch and a spark module activate the spark electrode when you turn the knob on a gas range's cooktop to the "light" position. If you don't hear the ticking sound of a spark jumping from the igniter electrode to the burner head when you start a burner, check the igniter electrode first. Clean the electrode if it's covered with spilled food. Replace the electrode if the ceramic insulation is broken.

If the electrode is okay, you may need to replace the igniter switch or spark module.
